- Resolved Question: What is the brightest star with exoplanets that is visible in the northern hemisphere?
I would like to view a star with exoplanets with my telescope. I am not sure which star would be the most visible. - Resolved Question: How are exoplanets around neutron stars possible?
Quite a few exoplanets have been found orbiting neutron stars... - Resolved Question: What is the technique used to detect chlorophyll on exoplanets?

- Tidal Heating on Some Exoplanets May Leave Them Waterless
As the number of exoplanets being discovered continues to increase dramatically, a growing number are now being found which orbit within their stars’ habitable zones. For smaller, rocky worlds, this makes it more likely that some of them could harbour life of some kind, as this is the region where temperatures (albeit depending on other [...] - Scientists help define structure of exoplanets
( DOE/Lawrence Livermore National Laboratory ) Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state of matter in exoplanets and figured out ... - Tidal heating may leave some alien planets waterless
Washington, Feb 13 (ANI): Some exoplanets may experience powerful tidal forces, which could strip them of water completely, thus leaving behind hot, dry worlds like Venus, a new study has revealed. - Russia to join search for exoplanets
MOSCOW, Feb. 1 (UPI) -- Russian astronomers say they will start their own search for planets outside our solar system following U.S. and French successes in finding such exoplanets. - Scientists Find New Clues About the Interiors of ‘Super-Earth’ Exoplanets
As we learned in science class in school, the Earth has a molten interior (the outer core) deep beneath its mantle and crust. The temperatures and pressures are increasingly extreme, the farther down you go. The liquid magmas can “melt” into different types, a process referred to as pressure-induced liquid-liquid phase separation. Graphite can turn into [...] - Hunter's Moons: Astronomers Use Kepler Spacecraft to Search for Exomoons
Astronomers have discovered a trove of exoplanets --more than 700 worlds in orbit around distant stars, with leads on thousands of additional suspects. So now, naturally, they're beginning to ask: What moons might be in orbit about these planets? [More] - What makes a planet livable? Five things scientists look for.
Since 1995, astronomers have been hunting in earnest for possible havens for life outside the solar system. So far, they've detected more than 550 extrasolar planets, or exoplanets. Another 2,000-plus possible planets are waiting in the wings for confirmation. Researchers are working on ways to identify a "potentially Earth-like" planet – even if it isn't an identical twin. One group, led by ... - Kepler Finds Multiple Exoplanets around Single Stars
Two decades ago, the only known planetary system started at Mercury and ended at Pluto. [More] - NASA discovers 26 new exoplanets
NASA's nearly doubled the number of known exoplanets in one fell swoop, with the announcement of 11 new planetary systems hosting 26 planets. read more - Models Help Define Exoplanet Structure
Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state (EOS) of matter in exoplanets and figured out the mass-radius and mass-pressure ...
