Volcanism on asteroids in early solar system08/20/14
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.
Galactic collisions could have created satellites
Satellite galaxies on edge of Milky Way and Andromeda challenge existing ideas on galaxy evolution. Also; continental drift may be speeding up, and Sun's magnetic poles reverse polarity.
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
New spacecraft to take astronauts to ISS unveiled
SpaceX unveils its new Dragon V2 capsule to take astronauts to the International Space Station. Also; giant windy stars go out with a bang, and were the slopes of a giant Martian volcano recently habitable?
Martian minerals made by microbes?
Discovery of microbe-made stevensite on Earth raises questions about minerals found on Mars. Also; the failed galaxy shielded by dark matter on a collision course with the Milky Way, and new study shows some parts of the Moon are wetter than others.
Turning light into matter
Scientists find an easy way of creating solid matter out of pure energy. Also; Jupiter's great red spot is shrinking, and shining a light on the dark side of the Milky Way.
Sun's first sibling discovered
Astronomers have discovered a star born from the same molecular cloud as our Sun. Also, ancient stars found in the Milky Way's halo, and empty space between stars used as a telescope to study pulsars.
Blast afterglow shines new light on black holes
Discovery of circular light patterns in gamma-burst afterglow challenges our understanding of black holes. Also; the search for life on other planets just got a lot harder, and element 117 joins the periodic table.
New stellar neighbour discovered
Astronomers discover our solar system's fourth nearest neighbour. Also; calls for an early-warning asteroid alert system grow, and new links discovered between the mass of a galaxy's central bulge and its ability to make new stars.
New type of matter discovered
Scientists discover a new type of matter called the tetraquark, which could point to new kinds of stars. Also; first detection of a habitable zone Earth-sized planet, and astronomers find the first possible exo-moon.
Water on early Mars disappears into thin air
Ancient Mars' atmosphere was too thin to keep liquid water on the red planet's surface, new research suggests. Also; new star birth formula discovered, and our supermassive black hole could be about to feast.
Quasars measure how fast early universe expanded
BOSS quasars give most precise data ever about the expansion of the early universe and offer clues about the nature of dark energy. Also; an ocean discovered on Saturn's moon Enceladus, and the exact age of the Earth and Moon.
