Red dwarf stars may be able to support habitable exoplanets after all -- through complex tidal interactions between star and planet, global magnetic fields could evolve, protecting hypothetical life forms from the red dwarfs' ferocious nature.
New research shows that the planet completes a rotation on its axis roughly 9 seconds faster than scientists previously thought.
Scientists have long puzzled over how gas planets like Jupiter and Saturn got to be so big -- now they think pebbles may be the answer.
You don't get to meet your double every day, but Jupiter and the sun share the same galaxy as their very own doppelgangers.
The scars of the solar system's violent past remain and they are just becoming visible as NASA's New Horizons mission races toward dwarf planet Pluto for a close encounter on July 14.
Venus is looking hot. And it looks like lava might be causing it.
The stellar runts of the galaxy probably aren't so great for nurturing Earth-like worlds, say scientists running new simulations of the formation of planets around a variety of stars.
Having already discerned the dwarf planet has distinct surface features, NASA's New Horizons mission has now spotted not just Pluto's largest moons, but the smallest natural satellites too.
