While there have been more than a few predictions made as to when we will discover life on a planet orbiting some far-flung star, what is only occasionally predicted is whether or not we […]

NASA's Hubble Reveals Rogue Planetary Orbit for Fomalhaut B

This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The planet will appear to cross a vast belt of debris around the star roughly 20 years from now. […]

Some Exoplanets May be Even More Habitable Than Earth

In the search for life elsewhere, the Earth is typically used as a standard against which other planets, or moons, are compared. Since our planet is teeming with […]

Planet Directly Observed Orbiting Distant Star

This false-color near-infrared image has been processed to remove most of the scattered light from the star Kappa Andromedae (masked out at center).The “super-Jupiter” companion, Kappa Andromedae b (upper left), lies at a projected distance of about 55 times the average distance between Earth and the sun and about 1.8 times farther than Neptune, […]
