Is it too hot or too cold? For two "Goldilocks" planets, the conditions seemed just right; unfortunately, though, these planets don't exist.
Scientists hunting for alien life may have a new tool in their arsenal. Researchers have created a powerful new model to detect life on planets outside of our solar system more accurately than ever before.
SPHERE, an instrument that's now mounted on the Very Large Telescope, is getting down to business. With its ability to use new, advanced techniques, it's showing astronomers more about nearby exoplanets, revealing a bit more about our universe.
How rare is life in our universe? It might just be far less likely than we once thought. Astronomers looking for habitable worlds have found that harsh space weather may doom life on planets near red dwarf stars.
Planets come in two different categories in our solar system, but there's also third category outside our system--planets that are about one to four times the size of Earth. Now, NASA's Kepler has learned a bit more about these categories.
Could "diamond" planets be far more common than previously thought? Scientists have discovered that carbon-rich planets, which could contain vast deposits of graphite or diamonds, may be abundant beyond Earth's solar system.
Working with data from NASA's Cassini, researchers have examined Saturn's hazy moon, Titan, in order to act as a stand-in for other exoplanets in order to develop a new and possibly more effective technique for studying their atmospheres.
Astronomers are learning more and more about the exoplanets outside of our solar system. Now, using one of the world's largest telescopes, scientists have managed to track the orbit of a planet at least four times the size of Jupiter.
Astronomers have uncovered a new gas giant through direct imaging. Located around GU Psc, a star three times less massive than the sun, the new exoplanet reveals a little bit more about the planetary bodies in our universe.
Last month, scientists announced the discovery of Kepler-186f, a planet 492 light years away in the Cygnus constellation. Kepler-186f is special because it marks the first planet almost exactly the same size as Earth orbiting in the “habitable zone” – the distance from a star in which we might...
NASA scientists are learning a bit more about the largest moon in our solar system, Ganymede. They've discovered that Jupiter's moon may have ice and oceans stacked up in several layers like a club sandwich.
