About 4.6 billion years ago, the solar system was little more than a tenuous disk of gas and dust. In the span of merely 10 million years, this soup evolved to form today's massive, complex planets. In the intervening period, ...
The most likely source of the water locked inside soils on the moon's surface is the constant stream of charged particles from the sun known as the solar wind, a University of Michigan researcher and his colleagues have concluded.
A satellite monitoring Earth's gravity field since 2009 will run out of fuel "in the coming days" and eventually crash, with little risk to humans, the European Space Agency said Friday.
Stargazers will be treated to a spectacular fireball show early next week when Earth hits a belt of comet debris known as the Perseids, astronomers say.
Objects that crashed to the ground in China have been identified as space debris, state media reported, after a Russian rocket carrying a communications satellite fell back to Earth minutes after lift-off.
Solar storms, space junk and the formation of the Universe are about to be seen in an entirely new way with the start of operations today by the $51 million Murchison Widefield Array (MWA) radio telescope.
For the past 8 years, NASA astronomers have been monitoring the Moon for signs of explosions caused by meteoroids hitting the lunar surface. "Lunar meteor showers" have turned out to be more common than anyone expected, with ...
'Shields to Maximum, Mr. Scott': Researchers use supercomputers to simulate orbital debris impacts on spacecrafts
We know it's out there, debris from 50 years of space exploration—aluminum, steel, nylon, even liquid sodium from Russian satellites—orbiting around the Earth and posing a danger to manned and unmanned spacecraft.
A plunging meteor which exploded with a blinding flash above central Russia , set off a shockwave that shattered windows and hurt almost 1,000 people in an event unprecedented in modern times.
Why does Russia seem to get so many bright meteors? Well at 6.6 million square miles it's by far the largest country in the world plus, with dashboard-mounted cameras being so commonplace (partly to help combat insurance ...
