Astronomer have discovered a planet about as massive as Neptune orbiting one of the most common types of stars in the universe.
A failed star looks to have the ingredients to make planets. So what do we call them?
New observations reinforce the validity of the "cosmological constant," a fudge factor that Albert Einstein introduced into his equations to balance the force of gravity.
Ever since Voyager 1 returned detailed images of Saturn's F ring back in 1980, astronomers have struggled to understand its bizarre features.
Giant clouds of gas and dust harboring embryonic stars rise majestically into space in a new picture from NASA's Spitzer Space Telescope.
Eta Carinae is one of the most massive stars in the Milky Way. Astronomers have long suspected a hidden companion.
Two small moons have been discovered orbiting Pluto, bringing the planet's retinue of known satellites to three and leaving scientist to wonder how it could be.
Within 24 hours, a very visible storm appears. The timing couldn't be better.
NASA's Spitzer Space Telescope has spotted the very beginnings of what might become planets around the puniest of celestial orbs -- brown dwarfs, or "failed stars."
Einstein's theory of general relativity can explain the cohesiveness of individual galaxies including our Milky Way, scientists say.
After decades chasing short-duration gamma-ray bursts, astronomers think they've finally figured out the source: merging neutron stars.
Dust devils on Earth and Mars are often likened to tornadoes. But in fact the mechanism behind them is completely different.
The galaxy, seen when the universe was very young, is more mature than theory predicts it should be.
A lot has been learned since the days when Mars was roundly feared by the masses. But Mars hoaxes continue.
An international group of astronomers trying to define the term planet may be finally nearing a decision, but a consensus is unlikely.
Stars race around a black hole at the center of the Andromeda galaxy so fast that they could go the distance from Earth to the Moon in six minutes.
A long-sought feature on the smoggy moon suggest a sea and rivers of methane or other hydrocarbons.
More storms are likely through early next week, and if they occur Earth will be in the sights.
A young Sun-like star appears to have one or more planets orbiting at distances similar to the giant planets in our solar system.
Communications on Earth disrupted. Forecasters expect more effects in coming days.
Observations from Spitzer Space Telescope reveal ingredients of comet Tempel 1.
New computer model challenges previous thinking on what drives Jovian jets.
