A planet about the size of Neptune but situated 33 times closer to its parent star than Earth orbits the sun is losing its atmosphere, forming a fat, comet-like tail in the process.
Astronomers may have discovered an exoplanet that has found the elixir to planetary youth, knocking billions of years off its age.
Europa is an ice-covered moon orbiting Jupiter that likely an ocean underneath. Perhaps that ocean contains life. Perhaps it doesn't. But we're not going to know for sure until we send a probe there to check things out.
Methane, a potential sign of primitive life, has been found in meteorites from Mars, adding weight to the idea that life could live off methane on the Red Planet.
Many thunderstorms in Saturn's atmosphere could be driving the gas giant's vast polar cyclones, according to new simulations inspired by observations from NASA's Cassini spacecraft.
Although our solar system doesn't contain gas giants with thick atmospheres enriched with helium, observations by NASA's Spitzer Space Telescope suggests the galaxy may be strewn with these planetary oddities.
Outer space might be the toughest environment for life, but some hardy microbes have been able to survive in it for surprising amounts of time.
NASA on Tuesday selected nine science instruments it believes will best address the burning question about whether Jupiter’s ocean-bearing moon Europa has indications of life.
