NASA plans follow-up trek to Mars

The Mars rover Curiosity is four months into its 2-year investigative visit to Mars. Now NASA is planning another rover trip to bring samples from Mars back to Earth. 

NASA's Voyager 1 hits a 'magnetic highway' out of the solar system

Scientists at NASA say the unmanned Voyager 1 spacecraft has reached the edges of the solar system. They estimate in a few months to a year Voyager 1 will become the first manmade object to leave the solar system and enter interstellar space.

Mars rover Curiosity soil analysis: why no news still isn't bad news

The Mars rover Curiosity has finished its first full soil analysis in Gail Crater, and its findings are consistent with those elsewhere on the planet. Researchers say the results form a 'baseline.'

NASA: Astronauts could survive Mars radiation

Radiation on the surface of the Red Planet is roughly similar to that experienced by astronauts on the international space station, report NASA scientists. The findings help researchers understand the planet's capacity for supporting life and will assist NASA in preparations for future manned flights to the planet. 

Are solar storms hazardous? It depends on how fast they move.

Studying the speed of particles in solar storms may help predict dangerous impacts: the slower the particles' speed, the higher the risk, say NASA scientists.

Climategate sequel? Scientist lies to get Heartland Institute documents.

Climate scientist, Peter Gleick, lied to acquire – then leak to the press – documents from the Heartland Institute, an organization that argues that global warming poses no threat. 

NASA Mars rover finds strong evidence of water

NASAs Opportunity Mars rover, which landed on the red planet nearly eight years ago, has discovered a mineral vein that was almost certainly deposited by water billions of years ago.

Tornado outbreak is possibly the deadliest in 37 years

The nation's Storm Prediction Center in Norman, Okla., reports that tornadoes this year have already claimed more lives than all of last year, possibly making this the deadliest tornado outbreak since the 1974.

Where polar bears might go if climate change doesn't slow

If climate change leads to ice collecting in one general area in the Arctic Ocean, it might be enough to provide a last 'refuge' for many Arctic inhabitants, including polar bears.

Voyager 1 spacecraft entering 'heliopause,' leaving solar wind behind

Voyager 1 reaching edge of the solar system, a region where the sun's influence wanes and the speed of the solar wind's outflow is zero, scientists report. Latest zone for Voyager 1: heliopause.

Voyager 1 nearing edge of solar system: NASA

Voyager 1: Since 2004, the Voyager 1 probe has been exploring a region of space where solar wind slows abruptly and crashes into the thin gas between stars.

At deepest hydrothermal vent yet found, an 'awe-inspiring' view

Scientists have found a hydrothermal vent community three miles beneath the sea near the Cayman Islands. Other vents have led to the discovery of new and exotic creatures.

Lawns may contribute to global warming

A study at the University of California Irvine says that greenhouse gas emissions 'would be lower if lawns did not exist.'

IBEX's ribbon in the sky: scientists unravel the mystery

NASA's Interstellar Boundary Explorer (IBEX) spacecraft recently detected a mysterious ribbon of particles at the edge of the solar system. Scientists now say it may have been formed by atoms reflected back into the solar system by the Milky Way's magnetic field.
