Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.   view more (2006-09-11)

Hubble captures outstanding views of mammoth stars
Two of our Galaxy's most massive stars have been scrutinised in an impressive view by the NASA/ESA Hubble Space Telescope. They have, until recently, been shrouded in mystery, but the new image shows them in greater detail than ever before.   view more (2008-11-26)

Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL).   view more (2008-12-12)

Hunt for planets outside solar system uncovers a small one
Perhaps edging closer to finding planets that harbor life, astronomers have discovered the smallest planet yet identified outside our solar system.   view more (2006-01-26)

Were the first stars dark?
Perhaps the first stars in the newborn universe did not shine, but instead were invisible "dark stars" 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter, a University of Utah study concludes   view more (2007-12-03)

Physicists and engineers search for new dimension
The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension.   view more (2008-03-11)

Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal Nature.   view more (2008-03-13)

Newly Born Twin Stars Are Far From Identical
Two stars, each with the same mass and in orbit around each other, are twins that one would expect to be identical. So astronomers were surprised when they discovered that twin stars in the Orion Nebula, a well-known stellar nursery 1,500 light years away, were not identical at all.   view more (2008-06-19)

Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth.   view more (2005-07-21)

Exoplanets clue to sun's curious chemistry
"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in Sun-like stars depends on whether or not they have planets."   view more (2009-11-12)

Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun.   view more (2008-11-19)

Kraken becomes first academic machine to achieve petaflop
The National Institute for Computational Sciences' (NICS's) Cray XT5 supercomputer-Kraken-has been upgraded to become the first academic system to surpass a thousand trillion calculations a second, or one petaflop, a landmark achievement that will greatly accelerate science and place Kraken among the top five computers in the world.   view more (2009-10-09)

Pulsar find boosts hope for gravity-wave hunters
Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or two, rather than about once a decade - the most... view more... (2003-12-02)

Bringing space down to Earth to explain how stars form
In a laboratory in Nottingham, scientists are now creating the uniquely harsh conditions encountered in interstellar space. In an environment where the pressure is only one ten billion billionth (one part in 10 to the power 13) of atmospheric pressure, and the temperature a mere 10 degrees above absolute zero, Dr Martin McCoustra and his... view more...

First extrasolar planets, now extrasolar moons
ESA is now planning a mission that can detect moons around planets outside our Solar System, those orbiting other stars! Everyone knows our Moon: lovers stare at it, wolves howl at it, and ESA recently sent SMART-1 to study it. But there are over a hundred other moons in our Solar System, each a world in its own right. A moon is a natural body... view more... (2003-10-09)

New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today.   view more (2009-02-19)

How do massive stars form?
Massive stars play a key role in the chemical and dynamical evolution of galaxies. The way massive stars form is still much debated among the astronomers' community: it is currently one of the hottest astrophysical topics.   view more (2005-11-09)

Chinese satellites meet European instruments in London for space mission pre-nuptials
The hardware inside a Chinese space satellite is currently undergoing its final tests in London to make sure that it can 'talk' with the European science instruments it will be carrying, in advance of its mission launch in 2003. 37 scientists from the Chinese Academy of Sciences (CAS) have spent the last three weeks in a converted seminar room at... view more...

Crash Test-Iconic Rings and Flares of Galaxies Created by Violent, Intergalactic Collisions, Research by Pitt and Partners Finds
The bright pinwheels and broad star sweeps iconic of disk galaxies such as the Milky Way might all be the shrapnel from massive, violent collisions with other galaxies and galaxy-size chunks of dark matter, according to a multi-institutional project involving the University of Pittsburgh.   view more (2008-11-24)

Stars Form Surprisingly Close to Milky Way's Black Hole
NASA's Chandra X-ray Observatory revealed a new generation of stars spawned by a super-massive black hole at the center of the Milky Way galaxy.   view more (2005-10-14)
