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.
NASA has confirmed an April 30 launch date for SpaceX's Dragon spaceship, the first private resupply mission to the International Space Station.
NASA's Mars Program Planning Group (MPPG) is starting to research its next Mars mission and is looking for help from scientists and engineers worldwide.
NASA’s Hubble Space Telescope has captured an image of NGC 4980, a spiral galaxy in the southern constellation of Hydra.
A Martian dust devil approximately 12 miles high (20 kilometers) was spotted whirling its way along the Amazonis Planitia region of Northern Mars just a few weeks ago.
Astronomers have combined infrared and X-ray observations from two space telescopes - Herschel and XMM Newton - to create a unique look at violent events within the giant galaxy Centaurus A.
The NASA Hubble Space Telescope recently observed a galaxy known as NGC 2683, which astronomers jokingly refer to as the "UFO Galaxy."
Complex organic compounds probably formed easily in the early solar system, say scientists at the University of Chicago and NASA Ames Research Center.
