Where Are All The Aliens?




Published on Jun 20, 2013 In this short explainer video, Universe Today publisher investigates the riddle of the Fermi Paradox; if the Universe is big, and old, and there are countless habitable worlds, why do we see no evidence of life? Where are all the aliens?

Seth Shostak: ET is (probably) out there - get ready




 
Published on Jul 15, 2015
 
SETI researcher Seth Shostak bets that we will find extraterrestrial life in the next
 twenty-four years, or he'll buy you a cup of coffee.
 
At TEDxSanJoseCA, he explains why new technologies and the laws of probability make the
 breakthrough so likely and forecasts how the discovery of civilizations far more advanced
 than ours might affect us here on Earth. (Filmed at TEDxSanJoseCA.)

A good possibility of Habitable Planets?

Here is a great new observation of the triple star system Gliese 667 from astrophotographer
 Efrain Morales of the Jaicoa Observatory in Puerto Rico.
 
 Recently, one of the stars, 667 C was found to have perhaps seven planets orbiting it!
 If all seven planets are confirmed, the system would consist of three habitable-zone
 super-Earths, two hot planets further in, and two cooler planets further out. Scientists say
 that the ?f? planet is ?a prime candidate for habitability.?

Are Intelligent Civilizations Doomed?




 
Published on Aug 25, 2014
 
One answer to the Fermi Paradox is the idea of the Great Filter; the possibility that
 something wipes out 100% of intelligent civilizations. That's why we've never discovered any
 aliens... they're all dead. Is that our future too?
 



Changing the atmosphere is daunting, but something we know we can do.

SETI talk leads to confrontation over nature of extraterrestrial life (Video)?




 
A lecture given by SETI scientist, Dr. Jill Tarter at the Paramount Theater in
 Charlottesville, Virginia on Monday night October 27th saw some uncomfortable moments when an
 audience member confronted the celebrated astronomer with notions that the organization was
 involved in a cover-up of what he thought was the reality of an extraterrestrial presence on
 planet Earth. SETI is an acronym for a group of radio astronomers meaning: The Search for
 Extra Terrestrial Intelligence.
 


 
This artist concept illustrates how two large, planet-sized objects could collide to create
 clumps of material in orbit around a star. They'd also create a lot of dust, which would glow
 in infrared light, something not seen around the Kepler star.

Astrophysicist Rene Heller Sets Alien Binary Code Test - Could You Crack It?
What is the typical body height of our interstellar counterparts?



 
The challenge is as follows: This is a call for a fun scientific challenge.
 
Suppose a telescope on Earth receives a series of pulses from a fixed, unresolved source
 beyond the solar system. The source is a star about 50 light years from Earth. The pulses are
 in the form of short/long signals and they are received in a very narrow band around an
 electromagnetic frequency of 452.12919 MHz.
 
A computer algorithm identifies the artificial nature of the pulses. It turns out the pulses
 carry a message. The pulses signify binary digits. Suppose further that you were, by
 whatsoever reason, put in charge of decoding this message. If you successfully decrypted the
 message, you should be able to answer the following questions:
 
1. What is the typical body height of our interstellar counterparts?
2. What is their typical lifetime?
3. What is the scale of the devices they used to submit their message?
4. Since when have they been communicating interstellar?
5. What kind of object do they live on?
6. How old is their stellar system?
 
The competition closes on 3 June, 2016

X-RAY STUDY SHOWS OLDER STARS MAY BE MORE SUPPORTIVE TO LIFE

 could be. Credit: NASA/CXC/M.Weiss

A Quick Look at GJ 176




 
Scientists are using X-rays to determine the hospitability of stars for life on exoplanets.
 Data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton were used to study 24 stars
 like our Sun that were at least one billion years old. They found these older stars had lower
 levels of X-rays and hence magnetic activity than other types of stars.
This relatively calm is good news for life trying to form on planets around these stars.
 Astronomers will continue to look at different properties, including X-rays, to assess
 the best place to look for life outside our Solar System.

HOW BADLY WILL HUMANITY FREAK OUT IF WE DISCOVER ALIEN LIFE?




The Search for Extraterrestrial Intelligence (SETI) listens for
radio signals from other civilizations. In this image,
radio-telescopes in SETI's Allen Telescope Array (ATA) are hard
at work with the Milky Way in the background.

group of meteorite hunters from the US. Scientists who studied
it suggested that it contained evidence of ancient Martian
microbial life. Image: By Jstuby at English Wikipedia, CC BY-SA 3.0,




Electron microscope images of the Martian meteorite ALH84001
showed chain-like structures that resembled living structures.

The authors of the study wanted to find out how people would
react to the discovery of alien life, and to the discovery of
potentially habitable exoplanets which might harbor life. In

Are We The First Advanced Civilization in The Solar System?




 
Humans are believed to be the most technologically advanced civilization that’s ever set foot
 on Earth, or really anywhere in the Solar System. But are we the first? Could there have been
 an advanced civilization that walked the Earth millions or even billions of years ago,
 and then died out long ago, their technology and structures lost to the eons.
And how could we know?

What Is A Dyson Sphere?




 
Published on Sep 19, 2013
 
A Dyson Sphere is a megastructure that could be built around a star to harness all the solar
 energy it gives off.
 
In this video we talk about the different kinds of Dyson Spheres, Dyson Clouds and other
 megastructures that could be built - and how we might even detect them from Earth.

Maybe Self-Replicating Robot Probes are Destroying Each Other. That’s Why We Don’t See Them



During the 1940s, Hungarian-American scientist John von Neumann developed a mathematical theory for how machines could endlessly reproduce themselves. This work gave rise to the idea of “von Neumann probes“, a class of self-replicating interstellar probes (SRPs) that could be used to do everything from exploring the Universe to seeding it with life and intervening in species evolution.


Where Are All The Alien Robots? The Chilling Idea Of Von Neumann Probes





As you know, I’m obsessed about the Fermi Paradox. Where are all the aliens? But an even stranger question is: where are all the robot aliens?

Von Neumann Probes





We often think of colonizing or even terraforming a planet, but how about colonizing every planet in your galaxy, and not by spaceships but by self replicating machines. In this episode, we will be looking at von Neumann probes, discussing many reasons why you’d use them, tied in with the Fermi paradox. ►Click here to subscribe: to astro focus ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/SEziF9P8ZZc Music: “Cylinder Five” by Chris Zabriskie “A Memory of Earth” by Markus Junnikkala

Could human civilization spread across the whole galaxy? - Roey Tzezana





View full lesson: Could human civilization eventually spread across the whole Milky Way galaxy? Could we move beyond our small, blue planet to establish colonies in the multitude of star systems out there? These questions are pretty daunting, but their (theoretical) answers were actually put forth decades ago. Roey Tzezana describes the conceptual von Neumann machine.
