NASA completes main Grail mission ahead of time

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.

From lunar rovers to wet wipes: protecting artifacts on the moon

NASA's a bit concerned that the rush to the moon created by Google's Lunar X Prize could damage historic sites there.

New-found exoplanet is evaporating away

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.

NASA tots up hazardous asteroids

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 scramjet accelerates hypersonic flight

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.

Vesta asteroid is ancient protoplanet

The asteroid Vesta is more like a planet or a moon, new data from NASA's Dawn spacecraft shows.

Sun moves too slowly for long-theorized 'bow shock'

Our sun is moving through the Milky Way more slowly than thought, new data from NASA's Interstellar Boundary Explorer (IBEX) satellite shows.

The biggest black holes prevent star creation

Scientists using the Herschel Space Observatory have discovered that galaxies with the most powerful, active black holes at their heart produce fewer stars.

Martian sand dunes are still on the move

NASA's Mars Reconnaissance Orbiter (MRO) has revealed that  sand dunes on Mars can put on a surprising turn of speed.

NASA detects light from super-Earth

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.

NASA uses moon as mirror to watch Venus transit sun

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.

Hubble sees the eye of a galactic storm

The image snapped by NASA’s Hubble Space Telescope may seem like a quiet patch of sky at first glance. 



These dwarf stars consume exoplanets

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.

Black hole caught shredding star

Astronomers have had their best look yet at a supermassive black hole in the process of shredding a star.

This nebula is running out of nuclear fuel

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.



Ancient asteroid strikes more frequent than thought

The Earth experienced many more giant asteroid strikes in the past than previously believed, new NASA research shows.

Galaxy found hiding inside another

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.

Rubber chicken launched into massive solar storm

It's been known for some time that solar storms represent a danger to the health of astronauts. But what about rubber chickens?

Arctic sea ice is leaking methane

NASA scientists have detected large releases of methane - a highly potent greenhouse gas - from the crumbling Arctic sea ice.

NASA says the moon's crust is being stretched



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.
