TrES-2b is literally darker, on average, than coal The planet may be too hot to support reflective clouds like those we see in our own Solar System, but even that would not explain why it is so dark. The research will be published in the journal Monthly Notices of the Royal Astronomical Society.

Summary & comments by Dan Eden for Viewzone "This first full-sky map of Sagittarius shows its extensive interaction with the Milky Way," Majewski said. "Both stars and star clusters now in the outer parts of the Milky Way have been 'stolen' from Sagittarius as the gravitational forces of the Milky Way nibbled away at its dwarf companion.

A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km.
The Sounds of Pulsars
Astronomers have found the brightest and youngest example yet of a fast-spinning star, suggesting that the extremely luminous versions of these super-dense objects may be far more common than thought. The spinning star, a millisecond pulsar called J1823-3021A, is located inside a packed conglomeration of stars called a globular cluster about 27,000 light-years from Earth in the constellation Sagitarrius. The pulsar emits incredibly intense high-energy gamma rays, which the researchers detected and studied using NASA's Fermi Gamma-Ray Space Telescope. Their analysis suggests the pulsar is just 25 million years old — a baby as far as these stars go, for millisecond pulsars tend to be a billion years old or so, researchers said. The pulsar's extreme brightness and youth challenge current ideas about how super-bright millisecond pulsars form and how widespread they may be, researchers said.

HubbleSite - Out of the ordinary...out of this world.
The Webb Space Telescope, Hubble's successor, will see in infrared, the light emitted by the farthest objects we can detect.
Picture Of The Week View All The NASA/ESA Hubble Space Telescope has produced the most detailed image so far of Messier 9, a globular star cluster located close to the centre of the galaxy.

The Universe is home to numerous exotic and beautiful phenomena, some of which can generate almost inconceivable amounts of energy. Supermassive black holes, merging neutron stars, streams of hot gas moving close to the speed of light ... these are but a few of the marvels that generate gamma-ray radiation, the most energetic form of radiation, billions of times more energetic than the type of light visible to our eyes. What is happening to produce this much energy? What happens to the surrounding environment near these phenomena?

Gamma-ray bursts (GRBs) are the most powerful explosions the Universe has seen since the Big Bang. They occur approximately once per day and are brief, but intense, flashes of gamma radiation. They come from all different directions of the sky and last from a few milliseconds to a few hundred seconds.

Welcome to the Herschel Astronomers' website provided by the Herschel Science Centre (HSC) primarily for the scientific community. For additional ESA and external Herschel related websites see link buttons above and " Useful links ". Herschel was launched on 14 May 2009! It is the fourth `cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched.

Photography has, since its inception, been a staple of the art world. But the artistic significance of astronomical imagery has become increasingly evident in recent years through a variety of exhibitions falling at the intersection of astronomy and art. The latest of these is The History of Space Photography, on display at the Williamson Gallery at the Art Center College of Design in Pasadena through May 6th.
