Endeavour final launch delayed
(Apr 30, 2011)

The launch of space shuttle Endeavour has been delayed until at least May 8 because of technical problems. The mission to the International Space Station (ISS) will be the second-to-last for NASA's 34-year old shuttle program. Centerpiece of the mission will be delivery of the Alpha Magnetic Spectrometer (AMS).

Youngest stars were whirling dervishes
(Apr 28, 2011)

The youngest stars in the universe were also among the fastest spinners a new study suggests. These "spinstars" may also have been more prone to gamma-ray bursts.

China plans its own space station
(Apr 27, 2011)

China's ambitions in space now extend to building a 60-tonne space station called Tiangong-1. To be assembled in low Earth orbit within a decade, the outpost will consist of a core module plus two laboratory units for carrying out experiments in zero-g, according to the state news agency, Xinhua.

The ATLAS experiment at the Large Hadron Collider
Has the God particle been found?
(Apr 25, 2011)

Rumors have been emerging over the Easter period from the Large Hadron Collider that the long sought-after Higgs boson, aka the "God particle", may have been unearthed. The data is as-yet unpublished and will have to go through many levels of scrutiny before we can be sure, but it seems that we may be on the verge of a new understanding of the subatomic universe.

hypothetical dark plants on an exoplanet in a binary star system
Black vegetation a possibility on some exoplanets
(Apr 24, 2011)

On worlds orbiting red dwarfs, plants may have adapted by having black leaves and flowers, according to new research. The study modeled howe flora might develop to cope with the unusual variations in light intensity and wavelengths especially in binary and multiple star systems containing dim red stars.

Galaxy Evolution Explorer images of large supernovae in small galaxies
Why the biggest star explosions happen in the smallest galaxies
(Apr 23, 2011)

New data from NASA's Galaxy Evolution Explorer has shed light on the mystery of why some of the largest supernovae occur in very lightweight galaxies. This puzzle first arose out of observations by the Palomar Transient Factory, a sky survey based at the ground-based Palomar Observatory. The new findings suggest an answer: whereas in big galaxies, high-mass stars tend to be gradually stripped of matter and therefore have less to explode at the end, the same kind of stars in small galaxies remain more-or-less intact until they blow up.

solar flare and sunspots
Solar flare was sparked by five spinning sunspots
(Apr 20, 2011)

A giant "X-class" solar flare unleashed in February was caused by five rotating sunspots working in concert. Images released from the Solar Dynamics Observatory clearly show the sunspots, which are centers of magnetic activity on the Sun's surface. As the magnetic fields build up, they "break", releasing vast amounts of energy in the form of heat and light.

Sierra Nevada's Dream Chaser concept
NASA funds further work on potential shuttle successors
(Apr 19, 2011)

NASA has awarded grants to four companies to push ahead with design and development of commercial spaceplanes to replace the shuttle and carry American astronauts into low Earth orbit. The agency is offering a total of $270m to Blue Origin, Boeing, Sierra Nevada Corp, and SpaceX to further develop plans to provide manned "taxi" services into space by the middle of the decade.

Neutrons could put string theory to the test
(Apr 18, 2011)

A novel experimental method that uses neutrons could be used to test current ideas about gravity and string theory, and offer clues to the presence of hidden dimensions of space and dark matter. The technique is designed to look for tiny variations in gravity as it acts on slow-moving neutrons in a cavity. A report in Nature Physics describes how neutrons were made to jump from one gravitational quantum state to another.

asteroid 2011 GP59
Fast-rotating asteroid winks for astronomer's camera
(Apr 17, 2011)

Video imaging of newly discovered near-Earth asteroid 2011 GP59 shows the object appearing to blink on and off about once every four minutes. Amateur astronomers, including Nick James of Chelmsford, Essex, England, have captured video of the interesting object. GP59 is about 50 meters (240 feet) long, and is thought to have a rotational period of about seven-and-a-half minutes.
