SpaceShipTwo's rocket motor test-fired for first time
(May 30, 2009)

The hybrid rocket motor that is intended to power tourist trips to the edge of space aboard Virgin Galactic's SpaceShipTwo has undergone its first successful test-firings. The rocket motor's design incorporates lessons learned after a fatal rocket propellant explosion in 2007.

Freeze-thaw cycle may explain Saturn moon's odd activity
(May 30, 2009)

If there is life on Saturn's bizarre, water-spewing moon Enceladus, it's about to spend a lot of time in the freezer. So concludes Norman Sleep of Stanford University, who says a perpetual cycle of melting and refreezing may offer the best explanation for why Enceladus seems so active today. In Sleep's scenario, Enceladus is now heading back into a long cold phase after a comparatively brief warm spell.

Crew doubles aboard space station
(May 30, 2009)

The International Space Station's crew has doubled after a Russian capsule carrying three astronauts docked at the orbiting outpost. The Soyuz TMA-15 capsule carrying the astronauts docked with the ISS at 1334 BST (0834 EDT). The new crew members will spend a total of six months aboard the station, raising its crew complement to six for the first time.

Rare radio supernova is nearest supernova in five years
(May 30, 2009)

The chance discovery last month of a rare radio supernova underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. "This supernova is the nearest supernova in five years, yet is completely obscured in optical, ultraviolet and X-rays due to the dense medium of the galaxy," said Geoffrey Bower, assistant professor of astronomy at the University of California, Berkeley.

Planet-hunting method succeeds at last
(May 29, 2009)

A long-proposed tool for hunting planets has netted its first catch – a Jupiter-like planet orbiting one of the smallest stars known. The technique, called astrometry, was first attempted 50 years ago to search for planets outside our solar system, called exoplanets. It involves measuring the precise motions of a star on the sky as an unseen planet tugs the star back and forth.

Yin-yang planet has phases like the moon
(May 28, 2009)

A super-hot planet 1500 light years away has been seen waxing and waning like the moon. The discovery hints that hot gas giants come in two varieties. The phases of Corot 1b were detected by a team at Leiden Observatory in the Netherlands, who analysed changes in the amount of red light from the system.

Giant galaxy Messier 87 finally sized up
(May 28, 2009)

Using ESO's Very Large Telescope, astronomers have succeeded in measuring the size of giant galaxy Messier 87 and were surprised to find that its outer parts have been stripped away by still unknown effects. The galaxy also appears to be on a collision course with another giant galaxy in the Virgo Cluster.

Earthlike planet
EPOXI Team develops new method to find alien oceans
(May 27, 2009)

Astronomers have found more than 300 extrasolar worlds so far. Sometime in the near future astronomers will probably find one that's just right for life-as-we-know – a planet with a solid surface that's the right distance for a temperature that allows liquid water. NASA-sponsored scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like extrasolar worlds have oceans.

Tagish meteorite
Space rock yields carbon bounty
(May 26, 2009)

Formic acid, a molecule implicated in the origins of life, has been found at record levels on a meteorite that fell into a Canadian lake in 2000. Cold temperatures on Tagish Lake prevented the volatile chemical from dissipating quickly. An analysis showed four times more formic acid in the fragments than has been recorded on previous meteorites.

Asteroid bombardment may have boosted early Earth life
(May 26, 2009)

The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. The new research opens up the possibility that life emerged as far back as 4.4 billion years ago, about the time the first oceans are thought to have formed.
