Delivering ants to space, sloshy fluids for robotic satellites, a study on antibiotic drug resistance and other small satellites to the International Space Station can be a tough job, and now Orbital Sciences Corporation...

A simulated Red Planet mission has begun at the Mars Desert Research Station in Utah, where six crewmembers are performing research that could lay the foundation for a real trip to Mars someday.

There's a new kind of planet to add to Kepler's cornucopia of alien worlds, and you won't find it in Earth's own solar system. Many of the newfound orbs, described here today (Jan. 6) at a meeting of the American Astrono...

You can find anything on the internet, right? A new study reveals, however, that you can't find evidence of time travelers on the internet. Credible time travelers, that is. The study was conducted by astrophysicist Robe...

NASA Fermi observatory makes the first gamma-ray measurements of a gravitational lens with an observation of Blazar B0218+357 behind a massive spiral galaxy. The gravity of the galaxy bends and amplifies the light of the...

The exoplanet candidate KOI-314c, which lies about 200 light-years away, is roughly as massive as Earth but is 60 percent larger, thanks to an extremely thick atmosphere, researchers said.

SPACE.com contributor Elizabeth Howell is part of a mock Mars mission in the Utah desert this week and wants to know: What questions do you have for a Red Planet simulation?

EchoStar said its purchase of Solaris Mobile would be followed "immediately" by deployment of another satellite for Solaris to cover Europe.

A review panel advised NOAA to launch a "gap-filler" satellite as a hedge against the loss of either the current or next civilian polar-orbiting weather satellite.

This beautiful space wallpaper is an artist's illustration of Supernova 1987A, which is based on real data and reveals the cold, inner regions of the exploded star's remnants (in red) where tremendous amounts of dust wer...

An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size measured. Surp...

More than three-quarters of the planet candidates discovered by NASA's Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth....
