Volcanism on asteroids in early solar system
Analysis of rare meteorite shows volcanic activity present on asteroids in the early solar system. Also; discovery of a red supergiant with a neutron star in its core, and scientists may have captured the first particles from interstellar space.
Birth of solar system triggered by dying giant?
A red giant star rather than a supernova may have triggered the birth of the Sun and solar system. Also; hurricanes on Earth producing gamma-rays that are picked up in space, and over 100 geysers observed on Saturn's ice moon Enceladus.
Rosetta reaches its comet
Rosetta becomes the first spacecraft to orbit a comet. Also; NASA prepares its next Mars rover mission as Opportunity sets a new distance record, and early Earth may have been habitable.
Earth gives the moon a soft centre
Earth's gravity melts layer around Moon's core, suggests study. Also; the Milky Way galaxy a lot smaller than we thought, and scientists invent the blackest black ever.
Rosetta seeing double over comet
Images of Rosetta's comet reveal it is actually two objects. Also; 'dancing' galaxies contradict the standard model of galactic evolution, and scientists map the magma path that lies below Mount Rainier.
Star dust created in supernova shockwave
Astronomers lift the veil on the creation of cosmic star dust. Also; Mars' levels of ultraviolet radiation recorded on Earth, and the maiden flight of Russia's new Angara rocket.
NASA launches satellite to monitor Earth's CO2
NASA's first carbon dioxide monitoring satellite blasts into orbit. Also; astronomers observe coronal rain on the Sun, and new clues about the origins of the planet Mercury.
Black hole trio discovered in distant galaxy
Astronomers discover three super-massive black holes in a distant galaxy. Also: scientists find a diamond star, and is Saturn's moon Titan actually a comet?
Black hole control switch found
Astronomers uncover the secret to controlling black holes. Also; has the gravitational waves discovery turned to dust? And Cassini sees possible waves on the seas of Saturn's moon Titan.
Planets were early starters
Planets began forming soon after the birth of our solar system. Also; possible echoes of the proto-Earth from deep in the planet's mantle, and Rosetta closes in on an historic comet landing
