Nasa have announced official confirmation of the first Earth-like planet orbiting in the habitable zone of another star.
An ocean of water that could support life lies under the surface of Saturn's tiny moon Enceladus, scientists have confirmed.
NASA has released satellite images of a new island that reared up from the sea off Pakistan's coast after a powerful earthquake.
The Mars Curiosity Rover has tweeted an image of the twilight sky and Martian horizon which includes Earth as the brightest point of light in the night sky.
Earth sits left of centre in the picture, with moon is just below.
The view was captured about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (31st January 2014). The image has been processed to remove effects of cosmic rays.
A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars."
An exceptionally close stellar explosion discovered on January 21 has become the focus of observatories around and above the globe, including several NASA spacecraft.
The blast, named SN 2014J, occurred in the galaxy 'M82' and lies about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type of supernova to occur during the life of currently operating space missions.
NASA has captured an impressive image of a cloud of material in space nicknamed the Hand of God.
The space matter was ejected from an exploded star, NASA said, and photographed using X-ray technology.
NASA calls the formation a "stellar corpse", identified as PSR B1509-58, and says it spins around at seven times per second, firing out material as it goes.
It was colder in Canada than on Mars on New Year's Eve.
The NASA Curiosity Rover, which has been on the red planet since 2012 recorded a temperature of -30C on 31st December 2013, while in Winnipeg the temperature reached almost -38C on the same day.
Wind chill meant that it felt even colder in Canada, around -49C (no information on wind chill was available for Mars).
Astronauts on board the International Space Station have sent New Year's greetings to the crowd in New York's Times Square.
The video, which was played on the iconic square's big screen, features NASA's Rick Mastracchio and Mike Hopkins, Koichi Wakata of the Japanese Aerospace Exploration Agency on the ISS and recently returned NASA astronaut Karen Nyberg.
NASA astronauts have completed their spacewalk to replace an ammonia pump on the International Space Station.
Two astronauts are around four hours in to a spacewalk to replace a broken ammonia pump on the outside if the International Space Station (ISS).
They completed the first spacewalk of three on Sunday, when they removed a damaged pump which is integral to the cooling system on board the ISS.
It is the second time NASA has performed a spacewalk on Christmas Eve - the first time being in 1999.
The 354-kilogramme cooling pump is about the size of a double-door refrigerator and extremely cumbersome to handle, with plumbing full of toxic ammonia. The pump replacement is a huge undertaking attempted only once before, back in 2010 on this very unit.
The two astronauts who tackled the job three years ago were in Mission Control, offering guidance. After exiting the Quest airlock Saturday, flight engineer Mike Hopkins made his way out to the work site.
He attached himself to a foot restraint at the end of the station’s 57-foot robotic arm so that Flight Engineer Koichi Wakata, the robotics operator for the spacewalks, could fly Flight Engineer Rick Mastracchio to the work site and position him for his various tasks.
A 5-hour, 28-minute spacewalk outside the International Space Station completed the first in a series of excursions to replace a degraded pump on the station's cooling system. A second spacewalk will take place on Christmas eve
A day later than planned, the extra time will allow the crew to resize a spare spacesuit on the space station.
