Galaxies have been known to take numerous forms. Indeed, elliptical blobs, swirling spiral arms, bulges, and disks are all known components of the wide range of galaxies astronomers have observed using telescopes like NASA's Hubble Space Telescope.
While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite spotted the previously unknown remains of a shattered star.
An analysis of a rock sample collected by NASA's Curiosity rover indicates ancient Mars could have supported living microbes long ago.
Northern latitudes are greening up, says a NASA-funded study, increasingly resembling the lusher latitudes of the south.
NASA's Hubble Space Telescope has captured a stunning image illustrating the blue bursts of hot young stars.
A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the "birth certificate" of an ancient star.
NASA has created a 3D reconstruction of ancient water channels below the surface of Mars, revealing evidence of a catastrophic flood in the last 500 million years.
The Curiosity ground team has been forced to switch the Mars rover to a redundant onboard computer, thanks to a memory problem.
The first NASA spacecraft designed to fly astronauts beyond Earth orbit since the Apollo era of yore is apparently well on its way to making a flight test next year.
It may look like something from "The Lord of the Rings," trilogy (think the Eye of Sauron), but this fiery swirl is actually a real-life planetary nebula known as ESO 456-67 imaged by NASA's Hubble space telescope.
