Ahead of major climate change talks in Durban, South Africa, China's top climate official said that economic turmoil in the West should not get in the way of fighting global warming.
NASA's Mars Science Laboratory, which includes the car-sized Curiosity rover, arrived on its Cape Canaveral launchpad on Thursday. But some experts worry about the lack of funding for Mars missions beyond 2013.
A report from the United Nations' weather agency, the World Meteorological Organization, found that greenhouse gases are more prevalent in our atmosphere than at any time since the Industrial Revolution.
Scientists at Switzerland's CERN research center threatened to turn physics upside down in September, when they measured a neutrino traveling at faster-than-light speeds. But now a new experiment by researchers in Italy suggests that the particles are actually obeying the cosmic speed limit.
The size of a small car, NASA's one-ton Curiosity Mars rover contains twice the number of scientific instruments as its predecessors, plus a drill that will allow it to bore into the Red Planet's rocks.
New research suggests that lakes of liquid water could be buried in the icy crust of Europa, a moon of Jupiter. The processes that create the lakes could also provide nutrients crucial for life on Europa, the scientists say.
The Phobos-Grunt spacecraft launched from Russia this week destined for Mars has yet to leave Earth orbit – and looks increasingly likely to tumble back to Earth with its full tanks of toxic fuel.
New research reveals that distant dwarf galaxies made stars at an astonishing rate. How did they do it? Scientists have theories, but none completely add up yet.
If controllers are unable to repair Russia's Phobos-Grunt probe, which was intended to fly to a moon of Mars but is instead stranded in Earth's orbit, it will eventually crash back to Earth. The probe contains toxic flues as well as a small amount of radioactive material.
The Western black rhino is now extinct, and a quarter of other mammal species are at risk of extinction, according to an assessment of more than 60,000 plant and animal species by the International Union for Conservation of Nature.
Why did the moon once have a magnetic field? A new proposal might hold the answer to a mystery that has baffled scientists for decades.
Asteroid 2005 YU55, a giant rock floating through space, looks like a giant rock floating through space, reports one astronomer, who observed the giant rock as it floated through space past the Earth on Tuesday.
Launched Tuesday, Russia's Phobos-Grunt spacecraft was meant to explore the Martian moon Phobos. But, in what could mark the fourth Mars probe failure in a row, Phobos-Grunt now threatens to become another piece of space junk uselessly orbiting Earth.
Bering Sea Storm: The National Weather Service warns that the storm of 'epic magnitude' that is making its way toward northwestern Alaska could be the biggest the state has seen in 40 years.
The size of a city block, Asteroid 2005 YU55 buzzed past Earth with just 201,700 miles of room to spare.
In what is will be the nearest flyby by a big space rock since 1976, the city-block sized Asteroid 2005 YU55 will buzz past our planet with a mere 201,700 miles of clearance at 6:28 pm Eastern Time on Tuesday.
The closest approach of 2005 YU55 will be at 6:28 p.m., Eastern time, on Tuesday. The asteroid will be roughly 203,000 miles from Earth, just inside the moon's orbital distance.
Using the Hubble Space Telescope, astronomers have captured light from the disk of dust and gas surrounding a supermassive black hole at the heart of a quasar.
Asteroid 2005 YU55 is as big as an aircraft carrier and the biggest space rock to come this close to Earth in 25 years. Scientists say asteroid 2005 YU55 will fly by Tuesday evening.
NASA researchers caught on film an 18-mile-long crack in the Pine Island Glacier in Antarctica. It looks like a huge new iceberg is forming.
