Milky Way's super-efficient particle accelerators caught in the act
Thanks to a unique "ballistic study" that combines data from ESO's Very Large Telescope and NASA's Chandra X-ray Observatory, astronomers have now solved a long-standing mystery of the Milky Way’s particle accelerators. They show in a paper published today on Science Express that cosmic...  |

 | NASA's Fermi Telescope Sees Most Extreme Gamma-ray Blast Yet
The first gamma-ray burst to be seen in high-resolution from NASA's Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest motions and the highest-energy initial emissions ever seen.
"We were waiting for this one," said... |

 | A ruler to measure the universe
A team of astronomers led by Nikhil Padmanabhan and David Schlegel has published the largest three-dimensional map of the universe ever constructed, a wedge-shaped slice of the cosmos that spans a tenth of the northern sky, encompasses 600,000 uniquely luminous red galaxies, and extends... |

 | 'Grandest Questions' of Astrophysics To Be Probed via Keck Telescopes
Yale's astronomers will be spending a lot more time in Hawaii from now on, but don't expect them to come back with suntans and macadamia nuts. Instead, they'll be spending long nights probing far into the distant reaches of the universe, thanks to a $12 million deal that will give them access... |

 | Jupiter's Great Red Spot is Shrinking
Scientists studying Jupiter’s Great Red Spot - the rapidly rotating Jovian 'hurricane' that is twice the diameter of Earth - have produced the best map ever of the wind speeds on the giant planet, a place where wind gusts are typically 250 miles per hour or higher. |

 | Biggest breach of Earth's solar storm shield discovered
Earth's magnetic field, which shields our planet from particles streaming outward from the Sun, often develops two holes that allow the largest leaks, according to researchers sponsored by NASA and the National Science Foundation.
"The discovery overturns a long-standing belief about how... |

 | Caltech researchers interpret asymmetry in early universe
The Big Bang is widely considered to have obliterated any trace of what came before. Now, astrophysicists at the California Institute of Technology (Caltech) think that their new theoretical interpretation of an imprint from the earliest stages of the universe may also shed light on what... |

 | Solar flare suprise
Solar flares are the most powerful explosions in the solar system. Packing a punch equal to a hundred million hydrogen bombs, they obliterate everything in their immediate vicinity. Not a single atom should remain intact.
At least that’s how it’s supposed to work.
"We’ve detected a... |

 | Astronomers Find the Two Dimmest Stellar Bulbs
It's a tie! The new record-holder for dimmest known star-like object in the universe goes to twin "failed" stars, or brown dwarfs, each of which shines feebly with only one millionth the light of our sun.
Previously, astronomers thought the pair of dim bulbs was just one typical,... |

 | Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This is an important step in finding the chemical biotracers of life as we know it on other worlds.
The Jupiter-sized planet, called HD 189733b, is too hot for life.... |
