Kepler, the planet-hunting all-star space telescope, may be down but, researchers hope, not necessarily out.
Astronomers have observed an ancient galaxy in the depths of outer space after catching a glimpse of light produced by an exploding star. When the dying star exploded more than 12 billion years ago, it so with so much force that the light it created was millions of times brighter than the the rest of the light in its galaxy. Light from that explosion has traveled from so far away that when the explosion occurred, Earth had not even formed yet.
The sun's magnetic field is about to turn round in the next few months, NASA said.
Twin brothers Mark and Scott Kelly did everything together growing up, serving as co-captains on their high school swim team and sitting side-by-side in AP Biology. Together they went on to become astronauts and are currently facing a year apart as Scott alone is slotted to spend a year on the International Space Station (ISS), while Mark watches from Earth.
There are some 1,400 Potentially Hazardous Asteroids (PHAs) currently occupying some degree of threat to human life, according to NASA's record-keeping, the orbits of which the agency has layed out in a new, eerily beautiful graphic.
Astronomers have discovered the lowest-mass exoplanet around a sun-like star. The planet, called GJ 504b, is several times the mass of Jupiter.
Mars's mysterious craters, called double-layered ejecta craters (DLEs), may be the result of impacts onto a surface covered by a layer of glacial ice tens of meters thick.
Just as the Curiosity rover marks its first 365 days on Mars, NASA has begun launch preparations for its next mission to the Red Planet.
A new study published in the journal Nature reveals the strongest evidence yet that short-duration gamma ray bursts (GRBs) are produced by the merger of super-dense neutron stars locked in a binary system.
Japanese researchers launched the world's first talking robot into space Sunday aboard a supply mission headed toward the International Space Station (ISS).
On Aug. 6 the Mars Curiosity rover will mark its first full year on the Red Planet, and to give the public an idea of what the rover's day-to-day has been like, NASA's Jet Propulsion Laboratory (JPL) has released a time lapse video of footage taken from a fisheye lens on the underside of Curiosity's chassis.
The monstrous galaxies that lie at the center of galaxy clusters are not the voracious predators scientists once stereotyped them as, according to new research from NASA's Spitzer Space Telescope.
The asteroid belt that exists between the orbits of Mars and Jupiter may also be a comet graveyard and some of the dead comets circling the Sun have the potential to become reignited after millions of years of inactivity, according to observations from astronomers at University of Anitoquia in Medellin, Colombia.
Using NASA's Spitzer Space Telescope, astronomers have spotted a young stellar system of what appears to be two developing stars surrounded by disks of star-formation residue. The stars, those who discovered say, are caught in a game of cosmic peek-a-boo while a third orbits at the periphery.
