Gamma-ray bursts detected by new satellite pinpointed
Cosmic gamma-ray bursts produce more energy in the blink of an eye, than the Sun will release in its entire lifetime. These short-lived explosions appear to be the death throes of massive stars, and, many scientists believe, mark the birth of black holes. Testing these ideas has been difficult, however, because the bursts fade so quickly and rapid action is required.

First stellar outcast discovered by astronomers
Astronomers have reported the discovery of a star leaving our galaxy, speeding along at over 1.5 million miles per hour. This incredible speed likely resulted from a close encounter with the Milky Way's central black hole, which flung the star outward like a stone from a slingshot. So strong was the event that the speedy star eventually will be lost altogether, traveling alone in the blackness of intergalactic space.

First measurement of Titan's winds from Huygens

Radio telescopes 'save the day' for Titan wind data
In what some scientists termed "a surprising, almost miraculous turnabout," radio telescopes have provided data needed to measure the winds encountered by the Huygens spacecraft as it descended through the atmosphere of Saturn's moon Titan last month -- measurements feared lost because of a communication error between Huygens and its "mother ship" Cassini.

New Arecibo sky survey may find 'dark galaxies'
Fitted with its new compound eye on the heavens, the Arecibo Observatory telescope, the world's largest and most sensitive single-dish radio telescope, is beginning a years-long survey of distant galaxies, perhaps discovering elusive "dark galaxies" -- galaxies that are devoid of stars.

Even in heaven, stars can only get so big
New research from the University of Michigan shows that there may be an upper limit to the mass of a star, somewhere around 120 to 200 times bigger than our sun. Knowing that there may be a limit to a star's mass answers a fundamental question, but raises a raft of other issues about what limits their mass, said Sally Oey, assistant professor of astronomy.

Deep inside these incubators are rapidly growing embryonic stars, whose warmth Spitzer was able to see for the first time with its powerful heat-seeking eyes.

Satellite sees matter speed-racing around a black hole
Using a 'radar-gun' technique, scientists have clocked three separate clumps of hot iron gas whipping around a black hole at 30,000 kilometres per second, about a tenth of the speed of light. The observation, made with ESA's XMM-Newton observatory, marks the first time scientists could trace individual blobs of shredded matter on a complete journey around a black hole.

Beyond Einstein: Spacetime wave orbits black hole
Astronomers have seen evidence of hot iron gas riding a ripple in spacetime around a black hole. This spacetime wave, if confirmed, would represent a new phenomenon that goes beyond Einstein's general relativity. These observations confirm one important theory about how a black hole's extreme gravity can stretch light.
