A spacecraft orbiting Venus has discovered an ozone layer in the planet's atmosphere, similar to that of Earth and Mars.

A team of astronomers have spotted gamma ray emissions coming from the Crab Pulsar far higher than theoretical pulsar models can explain.

September 2011 saw ice levels in the Arctic Sea drop to the second-lowest extent on record, according to data released by NASA and the National Snow and Ice Data Center at the University of Colorado in Boulder.

NASA has announced it will start accepting applicants for its next class of astronaut candidates in November.

NASA and the European Space Agency will combine forces to attempt an ambitious study of the sun.

The huge and powerful Alma telescope has begun probing into the universe, and astronomers hope it will reveal the earliest dawn of the cosmos.

Scientists have discovered a huge hole in the ozone layer above the Artic roughly five times the size of Germany, allowing harmful ultraviolet radiation to hit parts of Canada, Russia and Europe this spring.

NASA's Wide-field Infrared Survey Explorer (WISE) reveals that there are significantly fewer near-Earth asteroids in the mid-size range than previously imagined.

NASA's MESSENGER spacecraft, the first to achieve orbit around Mercury, has provided scientists with further important information about the planet, by revealing data that showed signs of widespread flood volcanism similar to Earth, provided clearer views of Mercury's surface, provided the first measurements of its elemental composition, and details about charged particles near the planet.

NASA has finally revealed where the UARS satellite landed when it fell back into Earth last Friday - in the Pacific Ocean just 300 miles away from Christmas Island.

China will take its first step to having its own space station tomorrow, as it prepares to launch the Tiangong-1, or "Heavenly Palace" space laboratory.

While much has been said about China's determination to expand and modernize its military material, the Asian giant is also focused on developing its space programme and is about to launch its first space lab module, an unmanned prototype for a future space station, which could lead to a space race between Beijing and Washington.

Predicting increased risks to air travelers from solar activity, NASA is developing a system to predict radiation entering Earth's atmosphere from space.

A sunspot over 60,000 miles in diameter is shooting out huge solar flares that could potentially blow the circuits of every electrical product on earth.

Will We Ever Know Where NASA Satellite Really Fell? One thing is for sure. A dead NASA Climate satellite definitely fell back to Earth early Saturday morning but NASA seem not have an idea as to where it landed and exactly where it has gone. Can NASA really have lost a satellite?

The need for faster broadband is not only felt here on Earth, but NASA has found that its current 6Mbps connection with Mars is just too slow, and has been trialling laser-powered 100Mbps broadband.

The NASA climate research satellite that plunged to earth on Saturday still hasn't been found according to U.S. space officials.

NASA's Upper Atmosphere Research Satellite (UARS), the space agency's largest defunct six-ton satellite the size of a bus is heading towards earth and is expected to crash within the next 24 hours, an while it is yet unknown where the space debris will fall, NASA admits the odds of Uars debris striking a person is about one in 3,200.

NASA's six-ton Upper Atmosphere Research Satellite, or UARS, has been slowly tumbling from orbit since its mission ended in 2005, and is now expected to re-enter the Earth's atmosphere and break apart on Friday, leaving scientists to try and find out where the debris will fall.

Nasa's six and a half ton satellite expected to hit earth on friday.

A NASA defunct six-ton satellite the size of a bus is heading towards earth and is expected to crash within the next 24 hours, but experts have no idea where it will land as its orbit is slowly decaying until gravity finally pulls it down as a fiery meteor.

A defunct NASA satellite the size of a bus is set to plunge through the Earth's atmosphere sometime this weekend, with officials still uncertain exactly where it is going to land.

NASA's Wide-field Infrared Survey Explorer (WISE) has uncovered data suggesting the family of asteroids thought to be responsible for the dinosaurs' extinction 65 million years ago may not have been the culprit.

An archaic NASA satellite the size of a bus is set to descend into the Earth's atmosphere this weekend, according to officials at NASA.

NASA's Kepler operation has confirmed the discovery of a circumbinary planet -- a planet compasses two stars, 200 light-years from Earth.

NASA's Kepler space probe has reportedly discovered the first ever planet orbiting two suns, lying a mere 200 light-years from Earth.
