Rosetta awoke from a decade of deep-space hibernation in January 2014 and immediately got to work photographing, measuring and sampling comet 67P/C-G. On September 30 it will sleep again but this time for eternity. Missi...

Investigators have determined that a "large breach" in the second stage helium system likely triggered the catastrophic Falcon 9 launch pad explosion that suddenly destroyed the rocket and Israeli commercial payload duri...

Supermassive black holes, millions to billions of times the mass of our Sun, are found at the centers of galaxies....

A team led by Case Western Reserve University researchers has found a significant new relationship in spiral and irregular galaxies: the acceleration observed in rotation curves tightly correlates with the gravitational ...

The four spacecraft orbiting Earth in formation as part of NASA's Magnetospheric Multiscale, or MMS, mission achieved a new record recently when the space between them was decreased from just over six miles to only four-...

There's something going on beneath the surface of Jupiter's icy moon Europa. But what?

In the last century, humans realized that space is filled with types of light we can't see - from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of th...

Ben Canales is an amazing astrophotographer, specializing in time-lapse animations of the night sky (see, for example, this, this, and this). He recently got his hands on a Canon MH20f-SH: A ridiculously sensitive camera...

German astronomers have measured the magnetic field in the vicinity of a supermassive black hole. A bright and compact feature of only 2 light-days in size was directly observed by a world-wide ensemble of millimeter-wav...

"We call it the 'globular cluster opportunity,'" says Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics (CfA). "A globular cluster might be the first place in which intelligent life is identified in o...

A 160-day-long simulated Red Planet mission began today (Sept. 24) at the Mars Desert Research Station (MDRS), a facility in the Utah desert operated by nonprofit group The Mars Society.

The famed astrophysicist has repeated his warning about humanity's potential first contact with intelligent aliens.

Investigators have traced the explosion that destroyed a SpaceX Falcon 9 on the pad Sept. 1 to a "large breach" in the helium system in the rocket's second stage, although the root cause of the accident remains unknown.
