Where are the Aliens? Answering the Fermi Paradox

Calculations show the Universe should be teeming with life, yet we have not yet made contact with alien beings. These facts have led to the Fermi Paradox, which simply asks why we have not yet contacted life on other worlds. Some of the top researchers in the world gathered in Paris on March 18 to discuss possible answers to this paradox. One group, called Messaging Extraterrestrial Intelligence, or METI, believes we may need to send information out to other worlds via radio telescopes, as a means of inviting communication.

Binary Stars May be Likely to Harbor Life, After All

Binary stars may be more likely to harbor life than once believed. Astronomers thought, until now, that life was unlikely to form in systems containing two or more stars. However, a new computer model developed by an undergraduate student of astronomy shows that as binary stars form in stellar nurseries, they are often passed by a third sun. Gravity from this passer-by can draw the two binary stars closer together, increasing the amount of area warm enough for liquid water to pool on planets. Water is necessary for life on Earth to exist, and planets with water are thought to be more likely to harbor life.

Preparing for E.T. – What do Aliens Look Like?

Astronomers at the SETI Institute are estimating that the human race will likely make contact with an alien species sometime in the next 25 years. Science writer James Maynard released a new look on thecosmiccompanion.com seeing what aliens may look like, based on the laws of science and evolution. Such aliens, he finds, are likely to have legs and some form of two or more eyes, and have a kind communication. Other than those features, extraterrestrials may have little in common with life on Earth.

Second Repeating Radio Burst Seen – Are Aliens Behind These Odd Events?

For just the second time in history, astronomers have witnessed a repeating fast radio burst. These events are formed far beyond our galaxy, and release more energy in a small fraction of a second than our Sun produces in decades. Researchers are uncertain what causes this phenomenon, although they may be the result of black holes or ultra-dense neutron stars colliding with each other. The event was witnessed by researchers at the new CHIME radio telescope in Canada, as that instrument underwent early testing. Only 60 of these events have ever been recorded, and this is just the second one ever seen repeating. Once CHIME is fully operational, astronomers hope to see several dozen fast radio bursts every day.

Could Alien Life Exist on Barnard b? It’s Possible!

A newly discovered super-Earth, Barnard b, may be capable of supporting alien life, researchers at Villanova University report. This world is roughly three times larger than the Earth, and experiences frigid temperatures. However, if it is a rocky world with a molten core, like Earth and Venus, this could provide enough heat to create oceans of liquid water that could support life. Astronomers are still uncertain if Bernard b has a solid surface, or if it is a gaseous world, similar to Uranus and Neptune. The next generation of telescopes may be able to make that determination, and possibly detect life if it exists on that alien world.
