A new study has confirmed that astronauts risk brain and vision abnormalities as a result of spending time in space.
An analysis of meteorite samples has revealed that there's more than one way of building amino acids in space, raising the odds of life elsewhere.
The moon's somewhat bizarre magnetic field may have been shaped by a massive asteroid impact, which left some of its material behind.
Skywatchers along the eastern US should have a ringside seat for a new NASA experiment designed to shed light on the Earth's jet stream winds.
One of the biggest solar storms in years is engulfing the Earth, following two flares that erupted on Tuesday.
The Hercules galaxy cluster - aka Abell 2151 - lies approximately 500 million light-years away in the constellation of Hercules.
Exceptionally high tides caused by a rare conjunction of celestial events could have placed the fateful iceberg in the Titanic's path.
Since last July, NASA’s Dawn spacecraft has been orbiting the asteroid Vesta and transmitting gigabytes of images and other relevant data.
Scientists say they've found more evidence of a major impact by a comet or asteroid, some 13,000 years ago.
Astronomers studying Venus have spotted a type of space weather outburst called a hot flow anomaly (HFA), which causes a temporary reversal of the solar wind that normally flows right past.
Observations from NASA's Cassini spacecraft have revealed an oxygen atmosphere around Saturn's moon Dione.
The numerous faint stars that comprise the Antlia Dwarf galaxy - first discovered in 1997 - are more than four million light-years from Earth.
Astronomers analyzing data from NASA's Hubble Telescope have identified what seems to be a clump of dark matter left behind from a collision between massive clusters of galaxies.

An investigation has revealed that a NASA laptop that was stolen last year had a lot of very important information.
Astronomers have spotted a number of young stars in the Orion nebula changing right before their very eyes.
By observing the way the moon reflects light from the Earth, astronomers have established that there's life on our planet - not as pointless as it seems, as the technique could help find life elsewhere.
Astronomers have been intrigued for years over the correlation between the mass of a galaxy's central black hole and the velocity of stars in a vast, roughly spherical structure known as its bulge.
An asteroid discovered last year could hit the Earth on 5 February 2040, says NASA - but really probably won't.
