How the universe began is a complex question involving study by vastly different branches of physics including particle physics,
nuclear physics and cosmology. A team in the US has brought together all of these disciplines to create a computer model simulating
the first few minutes after the Big Bang
A few seconds after the Big Bang, the universe was made of a thick, 10-billion degree 'cosmic soup' of subatomic particles.

What Is The Evidence For The Big Bang?

Almost all astronomers agree on the theory of the Big Bang, that the entire Universe is spreading apart, 
with distant galaxies speeding away from us in all directions.
Run the clock backwards to 13.8 billion years ago, and everything in the Cosmos started out as a single point in space. 
In an instant, everything expanded outward from that location, forming the energy, 
atoms and eventually the stars and galaxies we see today.
But to call this concept merely a theory is to misjudge the overwhelming amount of evidence.
There are separate lines of evidence, each of which independently points towards this as the origin story for our Universe.
The first came with the amazing discovery that almost all galaxies are moving away from us. 
In 1912, Vesto Slipher calculated the speed and direction of "spiral nebulae" by measuring 
the change in the wavelengths of light coming from them. He realized that most of them were moving away from us.
We now know these objects are galaxies, but a century ago astronomers thought these vast collections 
of stars might actually be within the Milky Way.
In 1924, Edwin Hubble figured out that these galaxies are actually outside the Milky Way. 
He observed a special type of variable star that has a direct relationship between its energy output and the time it takes to pulse in brightness. 
By finding these variable stars in other galaxies, he was able to calculate how far away they were.
Hubble discovered that all these galaxies are outside our own Milky Way, millions of light-years away.
So, if these galaxies are far, far away, and moving quickly away from us,
 this suggests that the entire Universe must have been located in a single point billions of years ago.
The second line of evidence came from the abundance of elements we see around us. 
In the earliest moments after the Big Bang, there was nothing more than hydrogen compressed into a tiny volume, 
with crazy high heat and pressure.
The entire Universe was acting like the core of a star, fusing hydrogen into helium and other elements.
This is known as Big Bang Nucleosynthesis. As astronomers look out into the Universe 
and measure the ratios of hydrogen, helium and other trace elements,
 they exactly match what you would expect to find if the entire Universe was once a really big star.
Line of evidence number 3: cosmic microwave background radiation.
In the 1960s, Arno Penzias and Robert Wilson were experimenting with a 6-meter radio telescope, 
and discovered a background radio emission that was coming from every direction in the sky - day or night.
 From what they could tell, the entire sky measured a few degrees above absolute zero.
Theories predicted that after a Big Bang, there would have been a tremendous release of radiation. 
And now, billions of years later, this radiation would be moving so fast away from us that the wavelength 
of this radiation would have been shifted from visible light to the microwave background radiation we see today.
The final line of evidence is the formation of galaxies and the large scale structure of the cosmos. 
About 10,000 years after the Big Bang, the Universe cooled to the point that the gravitational attraction 
of matter was the dominant form of energy density in the Universe. 
This mass was able to collect together into the first stars, galaxies and eventually
 the large scale structures we see across the Universe today.
These are known as the 4 pillars of the Big Bang Theory. 
Four independent lines of evidence that build up one of the most influential
 and well-supported theories in all of cosmology.
But there are more lines of evidence. 
There are fluctuations in the cosmic microwave background radiation, we don't see any stars older than 13.8 billion years, 
the discoveries of dark matter and dark energy, along with how the light curves from distant supernovae.
So, even though it's a theory, we should regard it the same way that we regard gravity, evolution and general relativity. 
We have a pretty good idea of what's going on, and we've come up with a good way to understand and explain it. 
As time progresses we'll come up with more inventive experiments to throw at. We'll refine our understanding 
and the theory that goes along with it.
Most importantly, we can have confidence when talking about what we know about the 
early stages of our magnificent Universe and why we understand it to be true.

This is the latest incarnation of the HDF video. The narration has been edited to include research from a paper
in Physical Review Letters (2004) which puts the size of the universe at 46.5 billion light years, not 78 billion as I originally stated.
In the video narration, I round that value up to 47 billion light years. I also took out Numa Numa guy.

Even though it�s said that the average human eye can discern from seven to ten million different values
and hues of colors, in reality our eyes are sensitive to only a very small section of the entire electromagnetic spectrum, diverse segments of the EM spectrum, from minuscule yet powerful gamma rays to incredibly long, low-frequency radio waves.

The Hubble Deep Field Abell 2744 Cluster

Galaxy cluster Abell 2744, with multiple images of individual galaxies marked.
These multiple images are produced by the cluster�s gravitational lens.

The Hubble Deep Field Abel 2744 Cluster(un marked also known as Pandoras Box)

Peering deep into the early universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope
reveals thousands of colorful galaxies swimming in the inky blackness of space. A few foreground stars from our own galaxy,
the Milky Way, are also visible. In October 2013 Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) began observing this portion of sky
as part of the Frontier Fields program. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744,
otherwise known as Pandora’s Box. While one of Hubble’s cameras concentrated on Abell 2744, the other camera viewed this
adjacent patch of sky near to the cluster. Containing countless galaxies of various ages, shapes and sizes, this parallel field observation is nearly as deep
as the Hubble Ultra-Deep Field. In addition to showcasing the stunning beauty of the deep universe in incredible detail,
this parallel field — when compared to other deep fields — will help astronomers understand how similar the universe looks in different directions.

Dark matter in the massive galaxy cluster Abell 1689, located 2.2 billion light-years away. The cluster contains about 1,000 galaxies
and trillions of stars. Hubble cannot see the dark matter directly. Astronomers inferred its location by analyzing the effect of gravitational lensing,
where light from galaxies behind Abell 1689 is distorted by intervening matter within the cluster. Credit: NASA, ESA, and Z. Levay (STScI)

Dark Matter in the Hubble Deep Field Abel 1689 Cluster

This Hubble image shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689,
containing about 1,000 galaxies and trillions of stars. Researchers used the observed positions of
135 lensed images of 42 background galaxies to calculate the location and amount of dark matter in the cluster.
They superimposed a map of these inferred dark matter concentrations, tinted blue, on an image of the cluster.
The greastest concentration of dark matter is in the cluster’s center.

NASA’s Spitzer Space Telescope captured this stunning infrared image of the center of the Milky Way Galaxy, where the black hole Sagitarrius A resides. Image: NASA/JPL-Caltech “We have used light of about 1 mm wavelength, which can be observed by mm telescopes like SPT, APEX or ALMA. At this wavelength the photons are produced by the thermal radiation of dust. The beauty of using this long wavelength is, that for a large redshift range (look back time), the dimming of galaxies [caused] by increasing distance is compensated by the redshift – so the observed intensity is independent of the redshift. This is because, for higher redshift galaxies, one is looking at intrinsically shorter wavelengths (by (1+z)) where the radiation is stronger for a thermal spectrum like the dust spectrum.”

An explosive quartet
Hubble sees multiple images of a supernova for the very first time 5 March 2015

Hubble sees multiple images of a supernova for the very first time! Galaxy cluster MACS j1149.5+223 and a supernova four times over An explosive quartet!: This image shows the huge galaxy cluster MACS J1149+2223,
whose light took over 5 billion years to reach us. The huge mass of the cluster and one of the galaxies within
it is bending the light from a supernova behind them and creating four separate images of it.
The light has been magnified and distorted due to gravitational lensing and as a result the images are arranged around
the elliptical galaxy in a formation known as an Einstein cross. A close-up of the Einstein cross is shown in the inset.

Cluster MACJ0416

Hubble Looks Into a Cosmic Kaleidoscope

At first glance, this cosmic kaleidoscope of purple, blue and pink offers a strikingly beautiful —
and serene — snapshot of the cosmos. However, this multi-colored haze actually marks the site of two colliding galaxy clusters,
forming a single object known as MACS J0416.1-2403 (or MACS J0416 for short).
MACS J0416 is located about 4.3 billion light-years from Earth, in the constellation of Eridanus.
This image of the cluster combines data from three different telescopes: the NASA/ESA Hubble Space Telescope
(showing the galaxies and stars), the NASA Chandra X-ray Observatory (diffuse emission in blue),
and the NRAO Jansky Very Large Array (diffuse emission in pink). Each telescope shows a different element of the cluster,
allowing astronomers to study MACS J0416 in detail.

Caption: Multiply lensed galaxies are marked in this image of MACS J0416.1-2403.
The brown lines create a contour map of mass concentrations according to the best-fit strong lensing model.
Multiple images of the same galaxy are indicated by the same number to the left of the decimal point.
The digit to the right of the decimal counts off the number of multiples. The most secure candidates are shown in blue;
the less secure are portrayed in magenta.

The ABELL 370 Cluster

The massive galaxy cluster Abell 370 as seen by Hubble Space Telescope in the final Frontier Fields observations.

The locations of Hubble’s observations of the Abell 370 galaxy cluster (right) and the adjacent parallel field (left) are plotted over a Digitized Sky Survey (DSS) image. The blue boxes outline the regions of Hubble’s visible-light observations, and the red boxes indicate areas of Hubble’s infrared-light observations. A scale bar in the lower left corner of the image indicates the size of the image on the sky. The scale bar corresponds to about 1/30th the apparent width of the full moon as seen from Earth. Astronomers refer to this unit of measurement as one arcminute, denoted as 1′.

The “parallel field” shows a wide assortment of galaxies stretching back through time and space.

GRAVITATIONAL WAVES WILL LET US SEE INSIDE STARS AS SUPERNOVAE HAPPEN

Hundreds of New Gravitational Lenses Discovered to Help Study the Distant Universe

General relativity tells us that everything, even light, is affected by the mass of an object. When a beam of light passes near a large mass, its path is deflected. This shift in the direction of light is known as gravitational lensing, and it was one of the first confirmed effects of Einstein’s theory.

Published on Feb 24, 2017 This time-lapse video sequence of Hubble Space Telescope images reveals dramatic changes in a ring of material around the exploded star Supernova 1987A. The images, taken from 1994 to 2016, show the effects of a shock wave from the supernova blast smashing into the ring. The ring begins to brighten as the shock wave hits it. The ring is about one light-year across. Discovered in 1987, Supernova 1987A is the closest observed supernova to Earth since 1604. The exploded star resides 163,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of our Milky Way. Credit: NASA, ESA, and R.

A Quick Look at Supernova 1987A

Published on Feb 24, 2017 On February 24, 1987, astronomers in the southern hemisphere saw a supernova in the Large Magellanic Cloud. This new object was dubbed “Supernova 1987A” and was the brightest stellar explosion seen in over four centuries. Chandra has observed Supernova 1987A many times and the X-ray data reveal important information about this object. X-rays from Chandra have shown the expanding blast wave from the original explosion slamming into a ring of material expelled by the star before it exploded. The latest Chandra data reveal the blast wave has moved beyond the ring into a region that astronomers do not know much about. These observations can help astronomers learn how supernovas impact their environments and affect future generations of stars and planets.

Black Holes!


No Escape from the Inside of a Black Hole


No Escape: Dive Into a Black Hole (Infographic) by Karl Tate - When matter is compressed beyond a certain density,
a black hole is created. It is called black because no light can escape from it. Some black holes are the tombstones
of what were once massive stars. An enormous black hole is thought to lurk at the center of the Milky Way galaxy.

Artist’s view of a black hole-powered blazar (a type of quasar) lighting up the center of a remote galaxy.
As matter falls toward the supermassive black hole at the galaxy’s center, some of it is accelerated outward at nearly
the speed of light along jets pointed in opposite directions. When one of the jets happens to be aimed in the direction
of Earth, as illustrated here, the galaxy appears especially bright and is classified as a blazar.

A Quick Look at XJ1500+0154


Published on Feb 6, 2017 Black holes are extremely compact and dense, generating incredibly powerful gravitational forces. When an object, like a star, wanders too close, these forces can rip that object to pieces. Some of the material from the doomed object is hurtled out into space. The black hole devours the rest. Astronomers just found a black hole gnawing on the remains of a star for over ten years. This is the largest meal, or the first clean-your-plate job, for a black hole ever seen.

CLOSEST STAR AROUND A BLACK HOLE DISCOVERED


This artist's impression depicts a white dwarf star found in the closest known orbit around a black hole. As the circle around each other, the black hole's gravitational pull drags material from the white dwarf's outer layers toward it. Astronomers found that the white dwarf in X9 completes one orbit around the black hole in less than a half an hour. They estimate the white dwarf and black hole are separated by about 2.5 times the distance between the Earth and Moon — an extraordinarily small span in cosmic terms. (Credit: NASA/CXC/M.Weiss)

On September 14, 2013, astronomers caught the largest X-ray flare ever detected from Sgr A*, the supermassive black hole at the center of the Milky Way, using NASA’s Chandra X-ray Observatory. This event was 400 times brighter than the usual X-ray output from the source and was possibly caused when Sgr A*’s strong gravity tore apart an asteroid in its neighborhood, heating the debris to X-ray-emitting temperatures before slurping down the remains.The inset shows the giant flare.

Published on Oct 20, 2012 An international team of astronomers, lead by researchers at the Max-Planck Institute for Extraterrestrial Physics (MPE), has directly observed an otherwise normal star orbiting the supermassive black hole at the center of the Milky Way Galaxy. Ten years of painstaking measurements have been crowned by a series of unique images obtained by the Adaptive Optics (AO) NAOS-CONICA (NACO) instrument on the 8.2-m VLT YEPUN telescope at the ESO Paranal Observatory. It turns out that earlier this year the star approached the central Black Hole to within 17 light-hours - only three times the distance between the Sun and planet Pluto - while travelling at no less than 5000 km/sec . In a break-through paper appearing in the research journal Nature on October 17th, 2002, the present team reports their exciting results, including high-resolution images that allow tracing two-thirds of the orbit of a star designated "S2" . It is currently the closest observable star to the compact radio source and massive black hole candidate "SgrA*" ("Sagittarius A") at the very center of the Milky Way. The orbital period is just over 15 years. The new measurements exclude with high confidence that the central dark mass consists of a cluster of unusual stars or elementary particles, and leave little doubt of the presence of a supermassive black hole at the centre of the galaxy in which we live . ESO Press Video eso0226 was produced by the Max-Planck-Society and shows the observed motions of S2 and other stars in this area.

Two Black Holes Merge into One


Published on Feb 11, 2016 A computer simulation shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged. This simulation shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look. It was created by solving equations from Albert Einstein's general theory of relativity using the LIGO data. The two merging black holes are each roughly 30 times the mass of the sun, with one slightly larger than the other. Time has been slowed down by a factor of about 100. The event took place 1.3 billion years ago. The stars appear warped due to the incredibly strong gravity of the black holes. The black holes warp space and time, and this causes light from the stars to curve around the black holes in a process called gravitational lensing. The ring around the black holes, known as an Einstein ring, arises from the light of all the stars in a small region behind the holes, where gravitational lensing has smeared their images into a ring. The gravitational waves themselves would not be seen by a human near the black holes and so do not show in this video, with one important exception. The gravitational waves that are traveling outward toward the small region behind the black holes disturb that region’s stellar images in the Einstein ring, causing them to slosh around, even long after the collision. The gravitational waves traveling in other directions cause weaker, and shorter-lived sloshing, everywhere outside the ring. This simulation was created by the multi-university SXS (Simulating eXtreme Spacetimes) project.

AFTER TWO BLACK HOLES COLLIDE, A PUZZLING FLASH

ON SEPT. 14, 2015, at almost the exact same time that a pair of sprawling gravitational-wave detectors heard the last gasp of a collision between two black holes, another, more perplexing observation took place. Over 500 kilometers above the surface of the Earth, the orbiting Fermi Gamma-Ray Space Telescope logged a passing burst of gamma rays, a high-energy form of light. The signal was so slight that the NASA scientists who run the satellite didn’t notice it at first.

This animation shows how the ASASSN-15lh most likely happened. A Sun-like star gets into the area of influence of a rapidly spinning supermassive black hole in the centre of a distant galaxy. While its orbit gets constantly closer to the black hole the star gets “spaghettified”, creating an accretion disc around the supermassive black hole. When it finally gets ripped apart close to the event horizon it creates a bright flash, that could resemble a superluminous supernova.

NEW METHOD FOR RESEARCHING ACTIVITY AROUND QUASARS AND BLACK HOLES


Artist’s impression of ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun. Credit: ESO/M. Kornmesser Ever since the discovery of Sagittarius A* at the center of our galaxy, astronomers have come to understand that most massive galaxies have a Supermassive Black Hole (SMBH) at their core. These are evidenced by the powerful electromagnetic emissions produced at the nuclei of these galaxies – which are known as “Active Galatic Nuclei” (AGN) – that are believed to be caused by gas and dust accreting onto the SMBH. For decades, astronomers have been studying the light coming from AGNs to determine how large and massive their black holes are. This has been difficult, since this light is subject to the Doppler effect, which causes its spectral lines to broaden. But thanks to a new model developed by researchers from China and the US, astronomers may be able to study these Broad Line Regions (BLRs) and make more accurate estimates about the mass of black holes.

ASTRONOMERS FIGURE OUT HOW BLACK HOLES CAN BLAST OUT RELATIVISTIC JETS OF MATERIAL ACROSS LIGHT YEARS OF SPACE

See model W-HR in Movie shows the data of 7,400 - 31,000 t_g. Unfortunately, the data of the first 0-7,400 t_g was corrupted due to output error. The accretion disc is initially turned slightly to the left and towards the viewer (black hole spin is pointing vertical in the movie). We see how the relativistic jets are launched (greatly disturbing the accretion disc) and how they point along the rotation axis of the disc (slightly to the left and towards the viewer), and not along the black hole spin. Over time, we see how the jets and disc change direction together, moving slightly to the right and aligning slightly with the black hole. Together, the disc and jets precess around the black hole spin about 40 degrees over the entire simulation. Precession of the accretion disc was predicted by Lense and Thirring in 1918 (and confirmed in previous work). Here, we present the first simulation ever to demonstrate that jets follow along with the precession of the accretion disc.

Astronomers using ESO’s MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely. It appears to be orbiting an invisible black hole with about four times the mass of the Sun — the first such inactive stellar-mass black hole found in a globular cluster. This important discovery impacts on our understanding of the formation of these star clusters, black holes, and the origins of gravitational wave events. This artist’s impression shows how the star and its massive but invisible black hole companion may look, as they orbit each other in the rich heart of the globular star cluster.

Anderson, and R. van der Marel (STScI)/NASA/ESA On April Fools' Day in 1988, a modern science classic by world-renowned theoretical physicist and cosmologist Stephen Hawking was published. Called "A Brief History of Time," it set off a wave of public curiosity about humanity's place in the universe.

NASA Captured A Super-Massive Black Hole! *2018*

In 2005 scientists discovered a huge energy burst which occurred 150 million light-years away from Earth inside a galaxy named 'Arp-299'. They thought it's a supernova explosion but it was't. In 2011, scientists discovered that the energy burst is elongating which makes it a jet of energy coming from unknown source. 2 months ago in 2018, research showed it was actually a Black Hole 20 million times more massive than sun eating a star. For the very first time, NASA recently captured the first ever image of a Black Hole. Watch Black Hole Image:
Black Holes are known to swallow everything coming in their path but that's not the end. With time they they emit enormous amounts of energy. In 2015 Hubble Telescope captured something that shocked the entire world. It was a burst of plasma jet 260 million light years away in space coming from an unknown source. Calculations showed that the jet was travelling at 98% the speed of light. Scientists finally concluded that they have captured a plasma burst coming from a super-massive Black Hole. Which is located inside a galaxy 260 million light-years away. Join me on instagram Source NASA Darkest Child A by Kevin MacLeod, License Artist:

What Are The Different Kinds of Supernovae?


Published on Mar 14, 2016 Supernovae are some of the most powerful explosions in the Universe, releasing more energy in a moment than most stars will release in their entire lifetimes. Support us at: More stories at: Twitter: @universetoday Facebook: Google+ - Instagram - Team: Fraser Cain - @fcain Chad Weber - weber.chad@gmail.com Created by: Fraser Cain and Jason Harmer Edited by: Chad Weber Music: Left Spine Down - “X-Ray” There are a few places in the Universe that defy comprehension. And supernovae have got to be the most extreme places you can imagine. We’re talking about a star with potentially dozens of times the size and mass of our own Sun that violently dies in a faction of a second. Faster than it take me to say the word supernova, a complete star collapses in on itself, creating a black hole, forming the denser elements in the Universe, and then exploding outward with the energy of millions or even billions of stars.

Hubble Movie Shows Movement of Light Echo Around Exploded Star
Release date: Nov 9, 2017 1:00 PM (EST)


Light from Supernova Bouncing Off Giant Dust Cloud Voices reverberating off mountains and the sound of footsteps bouncing off walls are examples of an echo. Echoes happen when sound waves ricochet off surfaces and return to the listener. Space has its own version of an echo. It’s not made with sound but with light, and occurs when light bounces off dust clouds. The Hubble telescope has just captured one of these cosmic echoes, called a “light echo,” in the nearby starburst galaxy M82, located 11.4 million light-years away. A movie assembled from more than two years’ worth of Hubble images reveals an expanding shell of light from a supernova explosion sweeping through interstellar space three years after the stellar blast was discovered. The “echoing” light looks like a ripple expanding on a pond. The supernova, called SN 2014J, was discovered on Jan. 21, 2014. A light echo occurs because light from the stellar blast travels different distances to arrive at Earth. Some light comes to Earth directly from the supernova blast. Other light is delayed because it travels indirectly. In this case, the light is bouncing off a huge dust cloud that extends 300 to 1,600 light-years around the supernova and is being reflected toward Earth. So far, astronomers have spotted only 15 light echoes around supernovae outside our Milky Way galaxy. Light echo detections from supernovae are rarely seen because they must be nearby for a telescope to resolve them.

Theories of Cosmology


BIG BANG THEORY: EVOLUTION OF OUR UNIVERSE 17 Dec , 2015 by Matt Williams


How was our Universe created? How did it come to be the seemingly infinite place we know of today?
And what will become of it, ages from now? These are the questions that have been puzzling philosophers
and scholars since the beginning the time, and led to some pretty wild and interesting theories.
Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created
in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos.
This is known as The Big Bang Theory.

Inflation Epoch With the creation of the first fundamental forces of the universe, the Inflation Epoch began,
lasting from 10-32 seconds in Planck time to an unknown point. Most cosmological models suggest that the Universe
at this point was filled homogeneously with a high-energy density, and that the incredibly high temperatures and pressure
gave rise to rapid expansion and cooling.

Is everything we know about the universe's expansion WRONG?
Measurements suggest it's growing faster than any theory can explain:
  • Researchers looked at 'standard candles' in nearby galaxies
  • These are stars of known brightness, used to measure their distances
  • Number doesn't fit with measurements of radiation left from Big Bang
  • If both are correct, it means something is missing in model of cosmology

The universe has been expanding since the Big Bang kickstarted the growth about 13.8 billion years ago.
And it is said to be getting faster in its acceleration as it gets bigger (illustrated).
Dark matter's gravity slows cosmic expansion, while dark energy pushes in the opposite direction and causes it to accelerate Read more: Follow us: @MailOnline on Twitter | DailyMail on Facebook

Data from stars in nearby galaxies such as M101 (pictured) has allowed researchers to complete the most precise measurement
ever made of how quickly the universe is expanding. They found it is expanding 8 per cent faster than predicted, which puts into
question our accepted model of the evolution of the universe

A team of astronomers using the Hubble Space Telescope have found that the current rate of expansion of the Universe
could be almost 10 percent faster than previously thought.

The researchers looked at a larger sample of stars than before in the Large Magellanic Cloud (LMC) pictured, the third closest galaxy to the Milky Way, to determine how fast the universe is expanding. They measured the value with an uncertainty of 2.4 per cent, down from the previous best result of 3.3 per cent COSMIC MICROWAVE BACKGROUND read more Follow us: @MailOnline on Twitter | DailyMail on Facebook

Much of what scientists know about dark matter and dark energy comes from radiation left behind from the Big Bang,
called cosmic microwave background (CMB) (pictured). The most exhaustive study of CMB - a portrait of the universe at 400,000 years of age
- was done in recent years by Esa's Planck observatory Read more: Follow us: @MailOnline on Twitter | DailyMail on Facebook

Time had a beginning but whether it will have an end depends on the nature of the dark energy that is causing it to expand at an accelerating rate.
The rate of this expansion may eventually tear the universe apart, forcing it to end in a Big Rip

The Largest Black Holes in the Universe


Published on Sep 26, 2012 Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy,
there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power.
Just how large, and violent, and strange can they get?
A new era in astronomy has revealed a universe long hidden to us. High-tech instruments sent into space have been tuned to sense
high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes and do not penetrate our atmosphere.
On the ground, precision telescopes are equipped with technologies that allow them to cancel out the blurring effects of the atmosphere.
They are peering into the far reaches of the universe, and into distant caldrons of light and energy. In some distant galaxies,
astronomers are now finding evidence that space and time are being shattered by eruptions so vast they boggle the mind.
We are just beginning to understand the impact these outbursts have had on the universe: On the shapes of galaxies,
the spread of elements that make up stars and planets, and ultimately the very existence of Earth. The discovery of what causes
these eruptions has led to a new understanding of cosmic history. Back in 1995, the Hubble space telescope was enlisted to begin
filling in the details of that history. Astronomers selected tiny regions in the sky, between the stars. For days at a time,
they focused Hubble's gaze on remote regions of the universe.
These hubble Deep Field images offered incredibly clear views of the cosmos in its infancy. What drew astronomers'
attention were the tiniest galaxies, covering only a few pixels on Hubble's detector. Most of them do not have the grand spiral
or elliptical shapes of large galaxies we see close to us today.
Instead, they are irregular, scrappy collections of stars. The Hubble Deep Field confirmed a long-standing idea that the
universe must have evolved in a series of building blocks, with small galaxies gradually merging and assembling into larger ones.

First Version of a 3D Map of Universe from the FastSound Project


Published on Aug 8, 2013 This is the first version of a 3D map of the Universe from the FastSound Project,
which is surveying galaxies in the Universe over nine billion light years away.
Using Subaru Telescope's new Fiber Multi-Object Spectrograph (FMOS), the map includes 1,100 galaxies
and shows the large-scale structure of the Universe about 4.7 billion years after the Big Bang. M
The area covers 2.5 times 3 degrees of the sky. The colors of the galaxies indicate their star formation rate,
i.e., the total mass of stars produced in a galaxy every year. The gradation in background color represents the number density
of galaxies; the underlying mass distribution (which is dominated by dark matter) would look like this if we could see it.
The project is ongoing and will eventually include 5,000 galaxies over ten billion light years away.
