A new study by a team of astronomers from the LPL indicates that the orbital inclinations of distant Kuiper Belt Objects could hint at the existence of a Mars-sized body in the area.

KENNEDY SPACE CENTER, FL - In another breakthrough milestone aimed at slashing the high cost of rocketry, the innovators at billionaire entrepreneur Elon Musk's SpaceX successfully launched a 'used' rocket for only the second time in history - that blazed a path to orbit with its BulgariaSat-1 commercial television comsat payload Friday afternoon, June 23, from the Kennedy Space Center and just minutes later landed upright and intact on an oceanic platform waiting offshore in the vast currents of the Atlantic ocean.

A team from SINTEF, and with the support of the ESA is looking to develop snake robots to assist astronauts aboard the ISS and conduct missions to asteroids, the Moon and Mars.

Relying on Hubble and gravitational lensing, a team of astronomers made the unexpected discovery of a galaxy that ceased star formation just three billion years after the Big Bang.

Yippy-ki-yay! Saturn rides the back of a prancing pony across the evening sky. See it the next clear night.

You can catch a glimpse of what its like to see NASA's Curiosity Mars rover simultaneously high overhead from orbit and trundling down low across the Red Planet's rocky surface as she climbs the breathtaking terrain of Mount Sharp - as seen in new images from NASA we have stitched together into a mosaic view; showing the perspective views above.

We know trips in space will take a long time. Can we go to sleep for the journey and then wake up when we arrive?

A researcher working with the ESA has proposed creating a fleet of magnetic tugs to safely and effectively remove space debris from orbit.

The ESA recently decided to move forward with its LISA mission, a trio of satellites that will be the first space-based gravitational wave detector.

It isn't every day we get a new moon added to the list of solar system satellites. The combined observational power of three observatories—Kepler, Herschel and Hubble—led an astronomical detective tale to its climatic conclusion: distant Kuiper Belt Object 2007 OR10 has a tiny moon.

The latest catalog to be released by the Kepler mission features and additional 10 potentially-habitable planets, and has led to some interesting conclusions about those that have been discovered so far.

Located in the Puppis constellation, approximately 1,600 light years from Earth, a bright open star cluster that is approximately 78 million years of age.

This summer, New Mexico-based aerospace company will be testing the aerospike engine, a concept which almost became part of the Space Shuttle
