Speediest Spinning Star Spotted By Southampton Scientist In Switzerland
A scientific researcher from the University of Southampton is leading an international team that has discovered the fastest-yet-seen accreting X-ray pulsar - University of Southampton
Saturn's Auroras Defy Scientists' Expectations
The dancing light of the auroras on Saturn behaves in ways different from how scientists have thought possible for the last 25 years. New research by a team of astronomers led by John Clarke of Boston University has overturned theories about how Saturn's magnetic field behaves and how its auroras are generated - Space Telescope Science Institute
Huge Explosion Traced To Exotic Star
A cataclysmic 'starquake' is thought to have caused a flare of radiation that ripped past the Earth on 27 December, battering instruments on satellites and lighting up our atmosphere - Nature
Pinpointing A Stellar Neighbor. A Feisty Red Dwarf In Antlia Becomes The Sun's 28th Nearest Neighbor
A faint red star found 5 years ago is the 28th closest star system to the Sun, say astronomers in the United States and Chile. Their precise parallax yields the best distance ever determined for the star - Astronomy
Earth Creates Powerful Gamma-Ray Flashes
Gamma rays that flash briefly in Earth's atmosphere during lightning storms are much more frequent and powerful than previously thought, a new study reveals - New Scientist
Mars Express Scuppers Greenhouse Hopes
If life exists on the surface of Mars, it has not encountered liquid water for several billion years, scientists say. It seems that the European Space Agency's orbiter, Mars Express, has found no evidence of the necessary greenhouse effect - Nature
The First Dark Galaxy? Astronomers May Have Discovered A Galaxy Without Stars
A cloud of gas in the Virgo cluster may be the first dark galaxy ever found, say astronomers in Britain, Australia, Italy, and France. The mysterious object has one-tenth the Milky Way's mass but consists of hydrogen gas and dark matter - with no detectable stars - Astronomy
Black Holes Bend Light The 'Wrong' Way
Astronomers could be misinterpreting their observations of distant stars, suggest mathematicians. Starlight may be bent in odd directions when it passes close to a rotating black hole, the researchers say, unexpectedly shifting its source's apparent position in the sky - Nature
Galaxy Clusters Formed Early
Only one billion years after the Big Bang, clusters of galaxies were already forming. This discovery pushes back the age of the youngest known galaxy cluster by a third, and shows that the largest astronomical objects in the Universe had already begun to form in one of the earliest epochs of the Universe that astronomers have been able to observe - Subaru Telescope
Moon Measurements Might Explain Away Dark Energy
Plans to trace the Moon's orbit with extraordinary new accuracy could reveal kinks in Einstein's theory of gravity and help explain the mysterious accelerating expansion of the universe, says a US researcher - New Scientist
