One of the biggest solar storms in years is engulfing the Earth, following two flares that erupted on Tuesday.
Since last July, NASA’s Dawn spacecraft has been orbiting the asteroid Vesta and transmitting gigabytes of images and other relevant data.
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.
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.
Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft seem to indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System.
An investigation has revealed that a NASA laptop that was stolen last year had a lot of very important information.
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.
NASA's hoping to reorganize its budget to allow a trip to Mars by the end of the decade.
NASA says the pace of research aboard the International Space Station (ISS) is accelerating - even though the shuttles used to build it were recently retired.
At the turn of the 19th century, the binary star system Eta Carinae appeared faint and rather undistinguished to astronomers.
NASA astronomers have positively identified space buckyballs in a solid form. Prior to this important discovery, the microscopic carbon spheres were found only in gas form within the cosmos.
NASA engineers have conducted an initial test of the J-2X engine powerpack at the Stennis Space Center.
NASA astronomers using the Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered.
New images from the European Space Agency’s Planck mission have revealed previously undiscovered islands of star formation, along with a mysterious haze of microwave emissions in our Milky Way galaxy.
NASA's received over 6,300 applications to join its astronaut corps - twice as many as usual.
A camera aboard one of NASA's twin Gravity Recovery And Interior Laboratory (GRAIL) lunar spacecraft has sent back footage of the far side of the moon.
NASA has for the first time analyzed the 'alien matter' in the interstellar wind.
A new NASA study has confirmed that it's greenhouse gases - not changes in solar activity - that are the main cause of global warming.
