NASA scientists were able to observe for the first time the powerful effects of an earthquake and tsunami combined, which broke off large icebergs a hemisphere away off the coast of Antarctica.

Moving to bolster private spaceflight in the post-shuttle era, NASA handed out a combined $10 million to seven firms vying to build commercial spaceships.

NASA reaches its destination, the Endeavour crater, where it will study rocks and terrains never seen by the human eye.

This week, the world was warned of solar flares that could possible shut down electrical and communication grids. Scientists are saying the sun will near maximum level of activity in 2013.

A new solar flare Tuesday is the biggest in several years and is part of a pattern of solar storms scheduled to last until 2020, experts say.

Scientists propose Wall-E type spacecraft.

An extremely powerful solar flare, which is the largest in the current solar weather cycle, rocked the Sun on Tuesday, resulting in coronal mass ejection (CME). But as the gigantic bursts of radiation occurred near the western limb of the sun, it is unlikely to wreak any serious havoc on Earth.

The sun was rocked by an extremely powerful solar flare on Tuesday, which, according to scientists, was the largest in four years. However, the bursts of radiation were not likely to cause any serious chaos on Earth since they were not aimed at the planet, they added.

Why don't humans give up hopes on spotting intelligent extra-terrestrial life? Because we haven't got any categorical evidence which suggests that alien life is non-existent and until proven otherwise extra-terrestrials could exist. Though probability of intelligent alien life is an intensely debated topic, SETI (Search for extraterrestrial intelligence- collective name for a number of activities people undertake to search for intelligent extraterrestrial life) is in the lookout for an ali...

Early Tuesday, the sun unleashed an extremely powerful solar flare, the largest of the current sun weather cycle which began in 2008.

An Antarctic ice shelf that had remained unshuffled for 46 years was broken by the Japanese tsunami in March, scientists have discovered. The Sulzberger Ice Shelf in the Antarctic registered the impact of the Japanese tsunami in 18 hours, when a huge iceberg began disintegrating and floating off to the Ross Sea.

The space agency has signed contracts on 30 new grants, hoping for a wave of innovation on new projects.

The best time to spot the annual Perseid meteor shower is this week, when the number of particles hitting the atmosphere is at its peak. Perseid shower is caused by debris from Comet Swift-Tuttle and has been observed for 2000 years. It normally peaks at 100 or more meteors per hour in the absence of moonlight on new moon.

A powerful tsunami in Japan back in March sent waves more than 8,000 miles away that sliced off icebergs in Antarctica twice the surface area of Manhattan, NASA scientists say. Details of the finding, the first observation of its kind, can be found in an article published in the Journal of Glaciology.

Scientists have new evidence that life on Earth may have come from space after finding essential building blocks of DNA in meteorites discovered in Antarctica.

The sun emitted a powerful solar flare on Tuesday, which is the largest in five years, but the bursts of radiation weren't in the direction of Earth and so there will be little impact on satellite and communication systems, scientists say.

NASA scientists were able to observe for the first time the powerful effects of an earthquake and tsunami combined, which broke off large icebergs a hemisphere away off the coast of Antarctica.

DNA molecules found on meteorites indicate that the building blocks for life on Earth originated in outer space.

The annual Perseid meteor shower, which is caused by debris from Comet Swift-Tuttle and observed for about 2000 years, will be hampered this year by the full moon, which happens when Earth comes between the Sun and the Moon.

Researchers announced that components of DNA exist in extraterrestrial meteorites that reach Earth, NASA said. The study suggests that the earliest forms of life may have been created from materials delivered to Earth from space, ABC News reported.

NASA scientists were able to observe for the first time the powerful force of an earthquake as it calved off large icebergs a full hemisphere away from the epicenter.
