Published on Nov 13, 2015 LISA Pathfinder will pave the way for future missions by testing in flight the very concept of gravitational wave detection:
it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy.
LISA Pathfinder will use the latest technology to minimise the extra forces on the test masses, and to take measurements.
The inertial sensors, the laser metrology system, the drag-free control system and an ultra-precise micro-propulsion system
make this a highly unusual mission.

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. For more information, visit

StarryNights - some of the largest observatories in time-lapse from Jan Hattenbach on Vimeo.
StarryNights is a collection of astronomical time-lapse videos recorded of the last three years.
From 2011 to 2014 we have been visiting astronomical observatories in Chile and La Palma - with our telescope and some cameras. This video features a compilation of our time-lapse videos we recorded.
The following observatories/telescopes appear in this video:
La Silla Observatory, ESO, Chile (3,6m ESO telescope, NTT telescope, MPG/ESO 2,2m telescope, Danish 1,54m telescope, among others)
Observatorio Roque de los Muchachos (ORM), La Palma, Spain (10,4m Gran Telescopo Canarias, NOT telescope, William Herschel 4,2m telescope, Liverpool telescope, Swedish 1m solar telescope, 17m MAGIC telescopes, among others)
Las Campanas Observatory, Chile (Magellan 6,5m twin telescopes, among others)
Paranal Observatory, ESO, Chile (Very Large Telescope, VST)
The time-lapses were a byproduct of our visual observing - because obviously, these sites are also the best in the world for visual observing and astrophotography. If you ever have the chance to spend a night at one of these observatories, consider yourself very lucky!
Thanks are due to following institutions for making this video possible:
European Southern Observatory (ESO)

We often speak of the discoveries and data flowing from astronomical observatories, which makes it easy to forget the cool factor.
Think of it � huge telescopes are probing the universe under crystal-clear skies, because astronomers need the dark skies to get their work done.
That�s what makes this astronomical video by Jan Hattenbach such a treat. He�s spent the past three years catching stunning video shots at observatories

from Alex Cherney Plus 1 week ago Not Yet Rated
in June 2011 I was very lucky to attend the inaugural STARMUS festival on Tenerife
and observe with the largest single-mirror optical telescope on the planet - 10-metre GranTeCan.
After spending five days at STARMUS listening to and chatting with the great astrophysicists and space legends
I decided to dedicate more time to astronomy science and film the observatories around the world.
This video, which was selected as the winner of the 2014 STARMUS astrophotography competition
(press announcement: tiny.cc/838tkx), is the result of over three years of work and includes the images of the following observatories:
* Roque De Los Muchachos Observatory, La Palma; * Australian Square Kilometre Array Pathfinder, Murchison, Australia; * Australia Telescope Compact Array, Narrarbri, Australia; * Parkes Radio Observatory, Australia; * Siding Spring Observatory, Australia; * Mount John Observatory, New Zealand Many thanks to Dermot Tutty for composing the original score for this video!

The Giant Magellan Telescope Organization Breaks Ground in Chile
Published on Nov 11, 2015 Concept video of the Giant Magellan Telescope MORE INFORMATION: Category News & Politics License Standard YouTube License
The Giant Magellan Telescope (GMT) will be one of the next generation of giant ground-based telescopes that promises to revolutionize our view and understanding of the universe, even out-performing the Hubble and James Webb space telescopes at certain wavelengths. It is currently under construction at the Las Campañas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2029. Dr. James Fanson is the project manager for GMT, responsible for leading the team of engineers, managers and scientists in turning this ambitious goal into reality. He grew up with a lifelong interest in astronomy and space exploration. After earning a Bachelor of Science degree at the University of Wisconsin and a doctorate at the California Institute of Technology in Pasadena, he joined NASA’s Jet Propulsion Laboratory, specializing in space telescopes, and continued to serve there for 28 years. During this time, Fanson was a member of the team that fixed the Hubble Space Telescope’s blurred vision in 1993. He later served as lead engineer for the design of the Spitzer Space Telescope and project manager for the Galaxy Evolution Explorer, two telescopes launched into space in 2003. After an extensive career with NASA, Jim now serves as Project Manager for the Giant Magellan Telescope since 2015. 🔔 Subscribe for more: 🖖 Share this video with a fellow space traveler: : 🔴 Watch my most recent upload 🚀 Help me improve the channel by joining the community on Patreon 🚀 Check out Launch Pad merchandise!

This video is a simulation of the GMT enclosure and the air flow through it. These lines are not precisely the airflow however: technically they are the "magnitude of the spatial gradient of the refractive index of air on a plane parallel to the wind and aligned with the enclosure symmetry axis". What this means in practice is this simulation shows the regions of optical turbulence – or random variations in air speed and temperature – that can affect the image quality of the telescope. We run simulations like this with various orientations of the telescope relative to the wind and for different environmental conditions such as temperature and wind speed. We analyze all this information to understand which aspects of the design of the enclosure negatively affect image quality, and what can be done about it. As the design of the enclosure moves into its final stages these kinds of simulations are important to ensure our design guarantees the best possible image quality from the telescope.

In the vein of “go big or go home,” the European Southern Observatory (ESO) has launched a stunning new website to showcase information about — and match the scale of — its Extremely Large Telescope (ELT), the highly anticipated observatory scheduled to have first light in 2025.
The ELT should see first light in 2024. This illustration shows the scale of the telescope, and also shows its segmented primary mirror, which is 39.3-metres in diameter (130-foot). Image Credit: ESO
The Extremely Large Telescope (ELT) will be the biggest ‘eye on the sky’ when it achieves first light later this decade. The telescope uses lasers as ‘guide stars’ to measure how much the light is distorted by turbulence in the Earth’s atmosphere. The deformable M4 mirror adjusts its shape in real time to compensate for these changes in the atmosphere, helping the ELT produce images 16 times sharper than the Hubble Space Telescope.

The Extremely Large Telescope (ELT), currently under construction in Chile, will be the world's biggest eye on the sky when it sees first light, planned for 2025. This revolutionary ground-based ESO telescope is set to be the largest of its kind in the world. 798 individual hexagonal segments will make up the telescope's main mirror, which spans 39 metres in diameter. The unique 5-mirror design of this telescope and advanced imaging technology will allow the ELT to produce images 15 times sharper than the Hubble Space Telescope. The ELT’s light-gathering power will allow astronomers worldwide to delve deeper and more clearly into our Universe, addressing the most prominent astrophysics questions of our time.

With a view 100 times bigger than that of NASA’s Hubble Space Telescope, WFIRST will aid researchers in their efforts to unravel the secrets of dark energy and dark matter, and explore the evolution of the cosmos. It also will discover new worlds outside our solar system and advance the search for worlds that could be suitable for life.
We used to think that the Universe expanded at a steady rate. Then in the 1990s we discovered that the expansion had accelerated. Dark Energy is the name given to the force driving that expansion. Image: NASA/STSci/Ann Feild

Published on Apr 17, 2014 Astronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them -- yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" that allows a telescope to photograph planets from 50,000 kilometers away. It is, he says, the "coolest possible science."

RADIO Observatories!
Published on Jul 4, 2016 ET, phone Beijing. The final triangular panel in the world’s largest radio telescope was lowered into place this weekend
as Chinese officials amped up the hunt for alien life. If intelligent beings lurk in the universe, the spectacular new Five-hundred-meter Aperture Spherical Telescope (FAST)
is uniquely equipped to find them, promised Peng Bo, director of the National Astronomical Observation (NAO).

The search for alien life will soon get a major boost as the Chinese government has finished construction of their enormous ET-hunting radio telescope.
At a cost of $180 million dollars, the massive telescope measures an astounding 1,640 feet in diameter, making it the largest such device in the world. With the construction stage finished, Chinese scientists will begin testing the telescope to ensure that it is running properly and hope to begin operation of the device in earnest this September. By virtue of its incredible size, the telescope will be able to detect extremely faint radio signals that otherwise would be missed by current technology here on Earth. While many Chinese citizens were celebrating the completion of the project, it is surely bittersweet for the 9,000 people who once resided in the area but were forced to relocate by the government. And although the powerful telescope boasts tremendous potential to possibly find evidence of aliens, one wonders if the Chinese government
would actually reveal any discoveries should they 'hear' from ET. Source: Daily Mail

Capturing the Radio Sky
Uploaded on May 11, 2015 These side-by-side videos show the sky as seen looking straight up from the ground at radio (left) and optical (right) wavelengths.
The radio movie covers 24 hours of observation with the new Owens Valley Long Wavelength Array, a project led by Caltech.
Each frame is a 9-second integration with the telescope, but only every tenth image is included. The optical movie was made using an all-sky camera
at Palomar Observatory and therefore only covers nighttime. Note that the radio sky is completely distinct to that visible at optical wavelengths. Almost all of the sources visible in the optical movie
are stars. The density of stars is highest in the Milky Way, which is visible to the naked eye.
Radio emission from our galaxy is also clearly visible in the LWA movie, but is produced not by stars but by cosmic rays spiraling in the magnetic
fields of our galaxy. The brightest source in the radio is not the sun—both Cassiopeia A and Cygnus A are brighter. However, when the Sun flares (as it does in the LWA movie),
it can become thousands of times brighter than anything else in the sky. Credit: Stephen Bourke/Caltech and the LWA team Category Science & Technology License Standard YouTube License

China switches on world’s largest radio telescope "FAST" today to search for alien transmission Listen to me
Published on Sep 24, 2016 (Sunday, 25 September 2016) China is set to start operating the world's largest single-dish radio telescope, enabling astronomers to probe farther and darker regions of space for the faintest signs of life. Scheduled to be launched on Sunday, the science mega-project is named after its huge dimensions: the Five-hundred-meter Aperture Spherical Telescope, or FAST. Built within a valley surrounded by naturally-formed karst hills in China's remote and mountainous southwestern Guizhou province, the FAST radio telescope's huge dish is equal in size to 30 football pitches and was constructed from 4,000 individual metal panels at a cost of around $180m. It also required the relocation of 10,000 people living in the vicinity of the huge structure. The feasibility study for the telescope was carried out over 14 years and construction took more than five years to complete. Chinese state media have enthusiastically focused on FAST's huge size, noting that it dwarfs by 200 metres the Arecibo Observatory in Puerto Rico, which at 305 meters in diameter had been the world's largest single-aperture telescope since the 1960s until the Chinese telescope was completed in July.

What exactly is a “normal” solar system? If we thought we had some idea in the past, we definitely don’t now. And a new study led by astronomers at Cambridge University has reinforced this fact. The new study found four gas giant planets, similar to our own Jupiter and Saturn, orbiting a very young star called CI Tau. And one of the planets has an extreme orbit that takes it more than a thousand times more distant from the star than the innermost planet.

and is still going strong. Credit NASA/JPL-Caltech
On Jan. 30th, 2020, NASA’s Spitzer Space Telescope was retired after sixteen years of faithful service. As one of the four NASA Great Observatories – alongside Hubble, Chandra, and Compton space telescopes – Spitzer was dedicated to studying the Universe in infrared light. In so doing, it provided new insights into our Universe and enabled the study of objects and phenomena that would otherwise be impossible. For instance, Spitzer was the first telescope to see light from an exoplanet and made important discoveries about comets, stars, and distant galaxies. It is therefore fitting that mission scientists decided to spend the last five days before the telescope was to be decommissioned capturing breathtaking images of the California Nebula, which were stitched into a mosaic and recently released to the public.

After 16 years of amazing infrared discoveries throughout the cosmos, NASA’s Spitzer Space Telescope mission is coming to an end. Join us on Jan. 22 at 1 p.m. EST for a live broadcast celebrating the life and legacy of one of our four great observatories. Mission members will discuss the observatory's far-reaching scientific impact and the incredible team that kept the mission going far longer than anticipated.

The IceCube detector is a cubic kilometre of Antarctic ice threaded with sensitive light detectors. Billions of cosmic neutrinos stream through us at the speed of light every second. Fortunately they have virtually no mass or charge, and generally don't interact with normal matter or we'd all look like Swiss cheese. And while we've known about them for 100 years, where these high energy particles come from and what's causing them to bolt across the universe has remained a mystery - until now.

A virtual journey, from our Solar System through our Milky Way Galaxy, based on data from the first (left) and second (right) release of ESA’s Gaia satellite. The journey starts by looking back at the Sun, moving away and travelling between the stars. A comparison between the two views shows the huge increase in number of stars and distances from the Sun between the two data releases. The view on the left is based on the 3D position of 1.4 million stars for which parallaxes had been estimated using the Tycho-Gaia astrometric solution (TGAS) as part of the first Gaia data release, published in 2016. The view on the right is based on the 3D position of nearly 97 million stars from the second data release, published in 2018. The majority of these stars have the most accurate parallax measurements in the dataset, which can be used to directly estimate distances to individual stars.

A*, doesn’t emit jets of material, while the other one in the EHT’s sights, in the M87 galaxy, does. Maybe the EHT will help answer that puzzling question.

In anticipation of the first image of a black hole, Jordy Davelaar and colleagues built a virtual reality simulation of one of these fascinating astrophysical objects. Their simulation shows a black hole surrounded by luminous matter. This matter disappears into the black hole in a vortex-like way, and the extreme conditions cause it to become a glowing plasma. The light emitted is then deflected and deformed by the powerful gravity of the black hole. Image Credit: Jordy Davelaar et al./Radboud University/BlackHoleCam
On 10 April 2019 at 15:00 CEST (Brussels time) the European Commission presented a ground-breaking discovery by Event Horizon Telescope - an international scientific collaboration aiming to capture the first image of a black hole by creating a virtual Earth-sized telescope. EU-funded researchers play a key role in the project. Black holes are extremely compressed cosmic objects, containing incredible amounts of mass within a tiny region. Their presence affects their surroundings in extreme ways, by warping spacetime and super-heating any material falling into it. The captured image reveals the black hole at the centre of Messier 87, a massive galaxy in the constellation of Virgo. This black hole is located 55 million light-years from Earth and has a mass 6.5-billion times larger than our sun. Six press conferences around the world took place simultaneously.

The EHI could capture images with a resolution five times higher than the EHT. Image Credit: F. Roelofs and M. Moscibrodzka, Radboud University Now a group of astronomers from the Radboud University in the city of Nijmegen, Netherlands, along with the European Space Agency and other partners, are developing a plan to get much sharper pictures of black holes.
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. Image Credit: EHT.

In 2019 astronomers captured the first direct image of a black hole. It was an image of the supermassive black hole at the heart of M87. And when many folks saw it, their reaction was “that’s it?” Which is understandable, given that the image is just a blurry, donut-shaped smudge. It isn’t much to look at. But an astronomical image is a small fraction of the data gathered by astronomers. Recently more of that data has been analyzed, including both the polarization of the light and the magnetic field surrounding the black hole.

Image: Light from a distant star is deflected by the atmosphere of the Earth by half a degree. After skimming the surface, it is bent again as it exits the atmosphere by one-half a degree. Light entering the opposite hemisphere does the same, creating a focal point. Rays entering the atmosphere higher up bend less because the atmosphere is thinner with altitude, so the result is a focal line. The trick is knowing which light can be effectively sampled.

I just love extreme ideas for ground and space-based telescopes, and Professor David Kipping from Columbia University's Cool Worlds Lab has presented an incredible idea for turning the entire planet into the lens of a telescope, thanks to the refractive power of the atmosphere. It could be the equivalent of a 150-meter telescope, detecting very faint objects as they change in brightness.
Image: Extinction effects for a terrascope at the Hill Sphere distance, roughly 4 Earth radii. Here, most of the infrared spectrum becomes usable for lensing. Image credit: David Kipping.
Image: This is Figure 11 from the paper. Caption: Amplification after extinction expected for a 1 metre diameter telescope at the Earth’s Hill radius (top), half the Hill radius (middle) and the Moon’s separation (bottom). Six atmosphere models are shown… [the color coding is provided in the paper, q.v.], which control temperature-pressure profiles (and thus refractivity profile) as well as the extinction computed using lowtran7 [a propagation model and computer code for predicting atmospheric transmittance and sky thermal and scattered radiance]. All models assume no clouds. Standard photometric filters highlighted in gray, except for L, M and N which are slightly offset to encompass the optimal regions. Credit: David Kipping.
Image: This is Figure 13 from the paper. Estimated transmission through the Earth’s atmosphere due to clouds for a Terrascope detector at a distance L. At one Hill radius (1,500,000 km), lensed rays travel no deeper than 13.7 km and thus largely avoid clouds, thereby losing less than 10% of the lensed light. Credit: David Kipping.

Of course, in our current stage of technological development, FOCAL itself is quite a reach, given our problems in getting to the outer Solar System — our farthest-flung craft even now are but a third of the way to where the lensing phenomenon could begin to be exploited. Well aware of this, David Kipping wondered if there wasn’t a way to explore the ‘bending’ of light in a different way, one that could help us learn how to untangle complex lensed images and develop near-term technologies at distances much closer to home. And it turns out there is, although it’s not a proposal that relies on gravitational lensing but rather the refraction of light.
When it comes to telescopes, bigger is better. That's why we're investing billions of dollars into a new generation of "extremely large telescopes", such as the Thirty Meter Telescope (TMT). But is 30 meters truly extreme? Could it be possible to ever build a telescope on the scale of a planet? In a new research paper by our very own Professor David Kipping, a solution for turning the Earth into a "Terrascope" is presented. Join us on a journey though the history of telescope inventions as well David's own personal journey to devising this new radical approach to the telescope.

The CHEOPS (CHaracterising ExOPlanets Satellite) spacecraft just opened the cover on its telescope. The spacecraft was launched on December 18th 2019 and has so far performed flawlessly. In one or two weeks we could get our first images from the instrument. CHEOPS is an ESA mission in partnership with Switzerland’s University of Bern. Its mission is not to find exoplanets, but to look more closely at stars with known exoplanets, and to watch as those planets transit in front of their star. It will watch those transits with a keen eye, and will determine the size of those planets with greater accuracy and precision. That will lead to better measurements of their mass, density, and composition.

The COSMO-SkyMed Second Generation satellite is an Earth observation spacecraft launched for the Italian Space Agency (ASI). The Characterising Exoplanet Satellite (CHEOPS) is an ESA mission dedicated to studying bright, nearby stars that already are known to host exoplanets in order to make high-precision observations.

As I’m recording this video near the end of 2019, the total number of confirmed exoplanets stands at 4,104. We’ve come a long way since the discovery of the first exoplanet orbiting a sunlike star back in 1995 with 51 Pegasi b. And the reality is that the race to find new exoplanets is only accelerating. New ground and space-based telescopes are turning up planetary candidates at an increasing rate. New techniques will find planets in entirely new ways. The bottom line is that over the next few decades, this mere 4000ish will multiply by orders of magnitude. So let’s run the clock forward and try to calculate what the future holds for exoplanets. How many worlds will we know about 3 decades from now, in the year 2050? Our Book is out!

Animation visualising ESA's CHaracterising ExOPlanet Satellite, Cheops, in orbit above Earth. Cheops will orbit Earth at an altitude of 700 km in a Sun-synchronous orbit riding on the day-night terminator – such a configuration is also called dawn/dusk orbit. This orbit allows Cheops to point its instrument always towards the night side of Earth, in order to limit the impact on the measurements of sunlight and reflected stray light from Earth. To maximize the fraction of the sky where Cheops can perform observations, the instrument can be pointed at any time anywhere in the sky up to 60 degrees from the anti-Sun direction. The satellite will communicate several times per day with the main Cheops ground station located at Torrejón de Ardoz, near Madrid, Spain, in order to downlink the science data and receive telecommands for further operations. Cheops will make observations of exoplanet-hosting stars to measure small changes in their brightness due to the transit of a planet across the star's disc. The information will enable accurate and precise measurements of the sizes of the orbiting planets to be made. Cheops will target stars hosting planets in the super-Earth to Neptune size range. By combining sizes with existing measurements of the planet masses, Cheops will provide an estimate of bulk density – a first step towards characterising planets outside our Solar System.

NASA is currently studying how we might build a radio telescope on the Moon. If it is built in the coming decades, we might finally see the aurora glow of a distant Earth. It’s difficult to do radio astronomy on Earth, and it’s getting harder every day. Our everyday reliance on radio technology means that radio interference is a constant challenge, even in remote areas. And for some wavelengths even the Earth’s atmosphere is a problem, absorbing or scattering radio light so that Earth-based telescopes can’t observe these wavelengths well. To overcome these challenges, astronomers have proposed putting a radio telescope on the far side of the Moon.

Whether these different organisations want to land astronauts, install a human outpost or mine minerals and make rocket fuel on the moon, it still lacks an exceptional and important asset-- A lunar radio Telescope. Why? Because this development will be uniquely poised to answer one of humanity’s greatest questions: What is our cosmic origin? - - Subscribe for more videos ► Business Enquiries ► - - All the lunar missions that are being planned along with all other missions that different organizations want to accomplish, will be of no use if we don’t seek answers to fundamental questions like “what is the universe made up of? What are we made up of?” And a telescope on the far side of the moon will help us answer these important questions!! So let’s take a look at why this is important and what NASA is planning to do about it. As mentioned earlier the universe constantly beams its history to us. For instance, the information of what happened long ago in the universe is contained in the long length radio waves that are present everywhere throughout the universe and most likely hold the details about how the first black holes and stars were formed. But there’s a problem. Our noisy radio signals and our atmosphere block these signals from coming to the earth and we can’t read them. The far side of the moon is the best place in the inner solar system to monitor these low-frequency radio waves and help us in detecting certain faint ‘fingerprints’ that the big bang left on the cosmos. The problem with our earth bound telescopes is that they encounter too much interference for electromagnetic pollution caused by human activity, whether it is short-wave broadcasting or maritime communication. On the top of that our ionosphere blocks the longest wavelengths from reaching our earth-based telescopes in the first place. We need these signals to understand and learn whether our universe inflated rapidly in the first trillionth of a trillionth of second after the big bang. This is the reason why NASA is in the early stages of planning what it would take to build an automated research telescope on the dark side of the moon. One of the most ambitious proposals is to build the Lunar Crater radio telescope or the LCRT - - "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license. in its different versions such as 1.0, 2.0, 3,0, and 4.0 – permitting commercial sharing with attribution given in each picture accordingly in the video."

The Astro 2020 describes the new array as a facility that “would be absolutely unique worldwide in both sensitivity and frequency coverage,” and concludes that “It is of essential importance to astronomy that the VLA and Very Long Baseline Array be replaced by an observatory that can achieve roughly an order of magnitude improvement in sensitivity compared to these facilities, with the ability to image radio sources on scales of arcminutes to fractions of a milliarcsecond.”
