NASA's Grail mission to study the moon from crust to core has completed its main task ahead of schedule, gathering information about the internal structure and evolution of the moon in unprecedented detail.
NASA's a bit concerned that the rush to the moon created by Google's Lunar X Prize could damage historic sites there.
MIT and NASA scientists believe they've found a planet, 1,500 light years away, that appears to be disintegrating from the heat of its parent star.
Observations from NASA's Wide-field Infrared Survey Explorer (WISE) indicate there are about twice as many potentially hazardous asteroids (PHAs) in lower-inclination orbits than previously believed.
NASA, along with a number of international partners, is currently working on the HIFiRE (Hypersonic International Flight Research Experimentation Program) program to advance hypersonic flight.
The asteroid Vesta is more like a planet or a moon, new data from NASA's Dawn spacecraft shows.
Our sun is moving through the Milky Way more slowly than thought, new data from NASA's Interstellar Boundary Explorer (IBEX) satellite shows.
Scientists using the Herschel Space Observatory have discovered that galaxies with the most powerful, active black holes at their heart produce fewer stars.
NASA's Mars Reconnaissance Orbiter (MRO) has revealed that sand dunes on Mars can put on a surprising turn of speed.
NASA scientists have, for the first time, seen the light from a planet outside our solar system that's a similar size to the Earth.
Just like human eyes, the Hubble Space Telescope can't observe the sun directly - so NASA scientists plan to study Venus's solar transit in June by using the moon as a mirror.
The image snapped by NASA’s Hubble Space Telescope may seem like a quiet patch of sky at first glance.
Astrophysicists at the University of Warwick have identified four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth.
Astronomers have had their best look yet at a supermassive black hole in the process of shredding a star.
Stars running out of nuclear fuel pass through the preplanetary or protoplanetary nebula stage - a short period in the cycle of stellar evolution that has nothing to do with planets.
The Earth experienced many more giant asteroid strikes in the past than previously believed, new NASA research shows.
Most galaxies are either roughly spherical or take the shape of a flat disk - but new observations from NASA's Spitzer Space Telescope show that the Sombrero galaxy is both.
It's been known for some time that solar storms represent a danger to the health of astronauts. But what about rubber chickens?
NASA scientists have detected large releases of methane - a highly potent greenhouse gas - from the crumbling Arctic sea ice.
New images snapped by NASA's Lunar Reconnaissance Orbiter (LRO) indicate the moon's crust is actually being stretched - forming minute valleys in a few small areas on the lunar surface.
