The International Space Station is about to get a little homier, thanks to a flower garden that should bloom in early 2016.

SpaceX may try to make history with its next launch later this month, returning its rocket to a landing pad rather than an ocean-based platform, a NASA official said today (Dec. 1).

A planet discovered last year sitting at an unusually large distance from its star - 16 times farther than Pluto is from the sun - may have been kicked out of its birthplace close to the star in a process similar to what...

Gravitational waves are tough to accurately measure in part because they warp detectors and their actor pints on Earth. ESA's Lisa Pathfinder mission will measure movement the precious metal cubes in a 'near-perfect grav...

Radio dishes always evoke wonder, as these giants search for invisible (to our eyes, anyway) radio signals from objects like distant quasars, pulsars, masers and more, including potential signals from extraterrestrials. ...

A Japanese spacecraft, which failed to make it into Venus orbit in 2010, is making a return trip to the planet after being stuck in solar orbit and engineers are hopeful it will complete its mission.

Astrophysicists have created a computer model that simulates a dying stars' magnetic guts before generating a cosmic monster.

The crowdsourced Integrated Space Plan is billed as "the most comprehensive vision of the next 100 years of space development ever produced" - compiled into a single graphic.

The U.S. Air Force awarded Johns Hopkins University $545,00 to study additive manufacturing techniques to make cooling chambers for liquid rocket engines.
