Currently the best place to search for life beyond the solar system. TRAPPIST-1 is an ultracool dwarf star -- it is much cooler and redder than the Sun and barely larger than Jupiter.
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.
A new research has suggested that Planets Similar to Earth Have Identical Interiors.
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..
A record-breaking star system has been discovered, playing host to nine alien worlds -- including three "super-Earths."
Could there really be billions of habitable worlds in our galaxy? Learn whether there could really be billions of habitable worlds in our galaxy.
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.
The first two Earth-like worlds orbiting another star have been detected, although neither are believed to be suitable for life.
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.
A recent study says that a particular mathematical technique could be used to detect forests on extrasolar planets.
(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.
Tides can render the so-called "habitable zone" around low-mass stars uninhabitable, according to new research. Until now, the two main drivers thought to determine a planet
