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.Read More Where are the Aliens? Answering the Fermi Paradox
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.Read More Binary Stars May be Likely to Harbor Life, After All
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.Read More Preparing for E.T. – What do Aliens Look Like?
