An Earth-like planet spotted outside our solar system is the first found that could support liquid water and harbor life, scientists announced today.

The rise and fall of species on Earth might be driven in part by the undulating motions of our Solar System through the Milky Way’s galactic plane, scientists say.

Like a jiggled jar of nuts, shaking on the near-Earth asteroid Itokawa is sorting loose rock particles on its surface by size, with the smallest grains sinking to the bottom.

Astronomers have laid down the cosmic equivalent of yellow “caution” tape around super hot stars, marking the boundary within which forming planets are likely to be blasted away.

A programming glitch was responsible for the loss of the Mars Global Surveyor (MGS) last year, a NASA review board announced today.

If symmetry is a sign of beauty, then the newly discovered Red Square nebula is one of the most beautiful objects in the universe.

A recently observed black hole eclipse is giving astronomers a chance to test two key predictions about the swirling disk of material that surrounds it.

The greenery of other worlds might actually be red, orange or yellow, theorists now say.

For the first time, water has been identified in the atmosphere of an extrasolar planet. Water is a crucial ingredient for life as we know it.

A Russian Soyuz rocket carrying two cosmonauts and the world’s fifth space tourist blasted into orbit Saturday, kicking off a two-day flight bound for the International Space Station (ISS).

Radio waves produced during solar flare eruptions on the Sun can potentially cripple the Global Positioning System (GPS) and other communication technologies here on Earth, scientists say.

Shifting sandstorms on Mars might be contributing to a recent bout of global warming on the planet that is shrinking the southern polar icecaps, scientists say.

The double sunset that Luke Skywalker gazed upon in the film “Star Wars” might be quite commonplace throughout the universe.

The motions of an asteroid with whirling parts are better known, thanks to a rare collaboration between professional and amateur astronomers.

NASA is preparing to test an inflatable structure that might one day be used to set up an outpost on the Moon.

Astronomers are getting their most detailed look yet at supersonic “bullets” of gas piercing through dense clouds of hydrogen gas in the Orion Nebula.

Scientists are puzzling over new Mars rover data revealing soil packed with sulfur and traces of water. It could be evidence of an evaporated spring or volcanic deposits from ancient gas vents.

A cluster of massive grey space boulders floating in the outskirts of the Solar System are the remnants of an ancient collision involving two rocky objects, one of which was nearly the size of Pluto.

Groundwater once bubbled up from beneath the surface of Mars to form transient, shallow pools before evaporating and leaving behind thick layers of salty minerals, a new computer model suggests.

Scientists find a new relationship between mass and orbital speed that applies to all galaxies, regardless of their shapes.

Future Mars rovers could be equipped with a new instrument that sifts through Martian soil for chemical signs of life.

The three mysterious debris rings lingering around Supernova 1987A might be the remains of an ancient two-star collision that set off an enormous stellar explosion, a new computer model suggests.

A mysterious explosion and expanding cloud of space debris is attributed to Briz-M rocket booster from a Russian Proton rocket launched a year ago.
