15 new planets hint at 'traffic jam' of moons in habitable zone
Volunteers from the Planethunters.org website, part of the Oxford University-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars.

An international team of astrophysicists has shown that planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if they had stellar companions with tighter orbits around them.

NASA-funded researchers analyzing a small meteorite that may be the first discovered from the Martian surface or crust have found it contains 10 times more water than other Martian meteorites from unknown origins.

Scientists have replaced the telescope by the microscope: Using the similarities between the structure of a crystal and the state of the cosmos in the early universe, they have explored a yet unconfirmed phenomenon, the formation of cosmic strings. These so-called "topological defects" are believed to have formed as the universe expanded shortly after the Big Bang.

Look up at the night sky and you'll see stars, sure. But you're also seeing planets - billions and billions of them. At least. That's the conclusion of a new study by astronomers at Caltech that provides yet more evidence that planetary systems are the cosmic norm.

A new study observes 13 smaller satellite galaxies orbiting around the immense Andromeda galaxy in a way similar to how the planets in our solar system orbit around the sun. The galaxies are orbiting on a thin, pancake-like plane at a scale 900 million times larger than our own solar system.

With its 2160 litres of liquid helium about to run out, the Herschel Space Observatory will, by the end of March, become just another piece of space junk.

As if space travel was not already filled with enough dangers, a new study shows that cosmic radiation - which would bombard astronauts on deep space missions to places like Mars - could accelerate the onset of Alzheimer's disease.

Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in rapidly pinpointing the locations of gamma-ray bursts (GRBs), the brightest explosions in the cosmos.
