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. 



SpaceX ISS mission set to launch this month

NASA has confirmed an April 30 launch date for SpaceX's Dragon spaceship, the first private resupply mission to the International Space Station.

NASA calls for ideas for future Mars missions

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.

This spiral galaxy is in the Hydra Constellation



NASA’s Hubble Space Telescope has captured an image of NGC 4980, a spiral galaxy in the southern constellation of Hydra.

Video: NASA spots a Martian dust devil

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.

Inside the dark heart of a cosmic collision

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.

Hubble spots a spiral galaxy edge-on

The NASA Hubble Space Telescope recently observed a galaxy known as NGC 2683, which astronomers jokingly refer to as the "UFO Galaxy."

Organics appeared naturally as solar system formed

Complex organic compounds probably formed easily in the early solar system, say scientists at the University of Chicago and NASA Ames Research Center.
