Within the Saturn system, there are many moons which could present the opportunity terraforming. But to do so presents many challenges.

Images from NASA's Mars Reconnaissance Orbiter have identified the lost Beagle 2 lander on the Martian surface, and might explain why the Beagle 2 failed to deploy.

Earlier this morning, SpaceX founder Elon Musk announced via twitter that his company plans to mount its first mission to Mars by 2018

The time to observe Mars is now, as the Red Planet heads towards a favorable opposition in May 2016. Here's our complete guide to all things Martian, including observing, imaging and more.

Planetary scientists using the Hubble Space Telescope have spotted a dark mini-moon orbiting the distant dwarf planet Makemake. The moon, nicknamed MK 2, is roughly 160 km (100 miles) wide and orbits about 20,000 km (13,000 miles) from Makemake.

It's tempting to think that life is plentiful in the Universe, if only we could locate it. But a pair of researchers using Bayesian analysis have poured cold water on that idea.

NASA has selected Aerojet Rocketdyne to design and develop an advanced solar electric propulsion (SEP) system that will serve as a critical enabling technology for sending humans and robots on deep space exploration missions to cislunar space, asteroids and the Red Planet.

A recent study released by CU Anschutz indicates that prolonged time in space can cause liver damage, adding to overall health concerns

Stunning high definition views of Earth's auroras and dancing lights as seen from space like never before have just been released by NASA in the form of ultra-high definition videos (4K) captured from the International Space Station (ISS).

Jupiter's four largest moons - the Galileans - have long been considered as possible sites for human habitation, and even terraforming

China claims success in an experiment designed to test mammalian reproductive cell development in low-gravity.

Are you having trouble keeping track of all the planets in the Solar System? Good news! Astronomers have found evidence that there's another huge planet far out in the Solar System. Textbooks will need to be rewritten again. You're welcome.

The team in charge of NASA's Dawn mission have asked to extend the spacecraft's journey to a third destination.

Now in orbit for just over a year at dwarf planet Ceres, NASA's Dawn spacecraft continues to astound us with new discoveries gleaned from spectral and imagery data captured at ever decreasing orbits as well as since the probe arrived last December at the lowest altitude it will ever reach during the mission.

The recovered SpaceX Falcon 9 first stage booster that successfully carried out history's first upright touchdown from a just flown rocket onto a droneship at sea, has just been moved back to the firms processing hanger at the Kennedy Space Center (KSC) for testing and eventual reflight.

A new paper concludes that a super-Earth size planet may reside in the habitable zone of a star only 16 light years away.

Recent findings from a team of researchers in South Africa have shown that supermassive black holes in distance are all spinning in the same direction
