Are we alone? Setting some limits to our uniqueness

A new paper shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.

Planets Similar to Earth Have Identical Interiors

A new research has suggested that Planets Similar to Earth Have Identical Interiors.

Earth From Afar Would Look Only 82% Right For Life

From Lunar orbit, Earth is obviously habitable. But from a distant point in the galaxy, not so much.

Our Place in the Cosmos

If our Galaxy truly contains many intelligent civilizations, some of which may be ahead of us by a billion years, how is it possible that we have not seen any sign of them yet? Nobody knows the answer to this so-called "Fermi Paradox," but..

Nine Exoplanets Discovered in Solar System's 'Twin' : Discovery News

A record-breaking star system has been discovered, playing host to nine alien worlds -- including three "super-Earths."

New super-Earth detected within the habitable zone of a nearby star

Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford

Fifty new exoplanets discovered by HARPS

Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. In this video news release we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life.

Earth-sized planets orbit distant star

The first two Earth-like worlds orbiting another star have been detected, although neither are believed to be suitable for life.

Fifty new exoplanets discovered by HARPS

Astronomers using ESO’s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By studying the properties of all the HARPS planets found so far, the team has found that about 40% of stars similar to the Sun have at least one planet lighter than Saturn.

Seeing the planets for the trees

A recent study says that a particular mathematical technique could be used to detect forests on extrasolar planets.

Densest known rocky planet: Astronomers unveil portrait of 'super-exotic super-Earth'

(PhysOrg.com) -- An international team of astronomers today revealed details of a "super-exotic" exoplanet that would make the planet Pandora in the movie Avatar pale in comparison.
