Do stars "sing?" They just may be able to, according to new research. A chance discovery has revealed that stars may generate sound that we are unable to hear.
MESSENGER's mission may be ending sometime this spring when the spacecraft runs out of propellant, but it's still chugging along until then.
Iron rain may have poured down on our early Earth. Scientists have found that at pressures rivaling those when worlds collide, iron vaporizes at far lower pressures than assumed.
Astronomers have discovered that more than a million hot, young stars are forming in a dusty cloud of molecular gases in a tiny galaxy near our own.
Astronomers have made the first ever direct observations of cosmic building-block dust in the center of our Milky Way galaxy.
Scientists have produced a new map of the moon's most unusual volcano, revealing that its explosive eruption spread debris over an area much greater than previously thought.
There may be planets in the habitable zone around most stars, according to a new study.
Scientists may have discovered a minor planet with a ring system like Saturn's. Called Chiron, the minor planet may reveal new insights into centaurs, which are a class of minor planets that possess qualities of both asteroids and comets.
Scientists have found evidence in meteorites that may hint at the discovery of a previously unknown region within the protoplanetary disk, a swirling disk of dust and gas that gave rise to the planets in our solar system.
Scientists have described possible planetary systems where a gravitational nudge from one planet with just the right orbital configuration could have a devastating impact on the orbit and climate of another, possibly habitable world.
On March 11, the sun unleashed a solar flare that peaked at 12:22 p.m.
