Hubble Breaks Record in Search for Farthest Supernova

Astronomy News - 4 April, 2013 - 05:00
NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.(author unknown)

NASA Administrator Statement on Alpha Magnetic Spectrometer

Astronomy News - 3 April, 2013 - 05:00
The following is a statement from NASA Administrator Charles Bolden on the first Alpha Magnetic Spectrometer (AMS) results announced Wednesday at the European Organization for Nuclear Research (CERN) in Switzerland. AMS is a cosmic ray particle physics detector on the exterior of the International Space Station.(author unknown)

Planck:Planck sees a cosmic journey 13 billion years in the making

Astronomy News - 2 April, 2013 - 16:40
Cosmologists using data from ESA's Planck satellite have compiled the first all-sky image of the distribution of dark matter across the entire history of the Universe as seen projected on the sky. This is made possible by analysing the tiny distortions imprinted on the photons of the Cosmic Microwave Background (CMB) by the gravitational lensing effect of massive cosmic structures. As photons travelled through these structures, which consist primarily of dark matter, their paths became bent, slightly changing the pattern of the CMB. Although noisy, this image is the first measurement performed over almost the whole sky of the gravitational potential that distorts the CMB, and is one of the highlights of Planck's cosmological results. With these unique data, cosmologists can investigate 13 billion years of the formation of structure in the Universe. The data agree very well with the expectations from the leading cosmological model that describes the origin and evolution of cosmic structure in the Universe.(author unknown)

INTEGRAL:Black hole wakes up and has a light snack

Astronomy News - 2 April, 2013 - 15:27
Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy.(author unknown)

Hubble:Hubble observes the hidden depths of Messier 77 [heic1305]

Astronomy News - 28 March, 2013 - 18:22
The NASA/ESA Hubble Space Telescope has captured this vivid image of spiral galaxy Messier 77, one of the most famous and well-studied galaxies in the sky. The patches of red across this image highlight pockets of star formation along the pinwheeling arms, with dark dust lanes stretching across the galaxy's energetic centre.(author unknown)
