Researchers from the German 'Loss of the Night' project have developed an app for Android smart phones, which counts the number of visible stars in the sky. The data from the app will be used by scientists to understand light pollution on a world wide scale.

Scientists have been searching for years to find proof of small meteors that they believe have been smashing into Saturn's rings. Cornell researchers and their colleagues announced today that they now have evidence of these collisions, thanks to images of Saturn's rings taken by NASA's Cassini spacecraft.

When galaxies form new stars, they sometimes do so in frantic episodes of activity known as starbursts. During these bursts, hundreds of millions of stars are born, and their combined effect can drive a powerful wind that travels out of the galaxy. These winds were known to affect their host galaxy - but this new research now shows that they have a significantly greater effect than previously thought.

Astronomers have released a new image of the outer atmosphere of Betelgeuse - one of the nearest red supergiants to Earth - revealing the detailed structure of the matter being thrown off the star.

Astronomers have found a galaxy turning gas into stars with almost 100 percent efficiency, a rare phase of galaxy evolution that is the most extreme yet observed. The findings come from the IRAM Plateau de Bure interferometer in the French Alps, NASA's Wide-field Infrared Survey Explorer and NASA's Hubble Space Telescope.

Hubble photographed a jet blasting dust particles off the sunward-facing side of the comet's nucleus. Preliminary measurements suggest that ISON's nucleus is no larger than three or four miles across.

Read moreMany collisions occur between asteroids and other objects in our solar system, but scientists are not always able to detect or track these impacts from Earth. The 'rogue debris' created by such collisions can sometimes catch us by surprise. UCLA space scientists have now devised a way to monitor these types of collisions in interplanetary space by using a new method to determine the mass of magnetic clouds that result from the impacts.

Without hi-tech magnetic sensors, rovers wouldn't be able to roam around Mars. These same sensors will soon boost terrestrial travel by improving the machinery that moulds parts for cars and aircraft here on Earth.

ESA's Herschel space observatory has solved a long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994.

Scientists working at Washington University in St. Louis have discovered two tiny grains of silica (the most common constituent of sand) in meteorites that fell to earth in Antarctica. Because of their isotopic composition these two grains are thought to be pure samples from a massive star that exploded before the birth of the solar system, perhaps the supernova whose explosion is thought to have triggered the collapse of a giant molecular cloud, giving birth to the Sun.
