Cassini Records Possible Supernova Shockwave On Saturn
2013-02-18 16:08:11

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists from the international Cassini spacecraft have detected subatomic particles that have been accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova. According to a report by the European Space Agency (ESA) that appeared recently in the journal Nature Physics, this acceleration may be the...

NASA NuSTAR Catches Glimpse Of Supernova Remnant, Black Holes
2013-01-08 12:04:09

redOrbit Staff & Wire Reports - Your Universe Online NASA has released a pair of new images captured by the Nuclear Spectroscopic Telescope Array (NuSTAR) — one depicting a pair of black holes lurking inside a spiral galaxy, and the other featuring a look at the supernova remnant Cassiopeia A. The two pictures, which were revealed Monday at the American Astronomical Society (AAS) meeting in Long Beach, California, “showcase why NuSTAR is giving us an unprecedented look...

Astronomers Spot Fastest Moving Pulsar Ever
2012-06-29 13:31:30

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers used X-ray observations, combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey to find evidence for the record-breaking pulsar. The XMM-Newton image was produced when a massive star exploded as a supernova, leaving behind a...

Image 1 - New Facets Of The Vela Pulsar Wind Nebula

Astronomers studying the Vela pulsar wind nebula with ESA's INTEGRAL observatory have successfully resolved its morphology in the hard X-ray band, for the first time. This pulsar-powered nebula is the most extended individual source yet observed at these energies. The study exploited a special imaging technique to reveal a new component of the source that likely consists of highly energetic electrons that have escaped from the core of the nebula in the last few thousand years. One of the...

Image 1 - Fermi Shows That Tycho's Star Shines In Gamma Rays

[ Watch the Video ] In early November 1572, observers on Earth witnessed the appearance of a "new star" in the constellation Cassiopeia, an event now recognized as the brightest naked-eye supernova in more than 400 years. It's often called "Tycho's supernova" after the great Danish astronomer Tycho Brahe, who gained renown for his extensive study of the object. Now, years of data collected by NASA's Fermi Gamma-Ray Space Telescope reveal that the shattered star's remains shine in...

Image 1 - Fermi Finds Cosmic-ray Cocoon In The Heart Of Cygnus
2011-11-29 12:32:33

[ Watch the Video ] The constellation Cygnus, now visible in the western sky as twilight deepens after sunset, hosts one of our galaxy's richest-known stellar construction zones. Astronomers viewing the region at visible wavelengths see only hints of this spectacular activity thanks to a veil of nearby dust clouds forming the Great Rift, a dark lane that splits the Milky Way, a faint band of light marking our galaxy's central plane. Located in the vicinity of the second-magnitude star...

Image 1 - Fermi Census Highlights Cosmic Mysteries
2011-09-11 04:32:43

  Every three hours, NASA's Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite's scientists reanalyze all of the data it has collected, exploiting updated analysis methods to tease out new sources. These relatively steady sources are in addition to the numerous transient events Fermi detects, such as gamma-ray bursts in the distant universe and flares from the sun. Earlier this year, the Fermi team...

A New Atlas Of The Milky Way

  Sino-German research group draws a new map at the Urumqi radio telescope and discovers two supernova remnants It may not be much use to hitchhikers through the galaxy, but it is extremely valuable to astronomers: the new radio atlas of the Milky Way. After almost ten years of work, researchers at the Max Planck Society and the Chinese Academy of Sciences have completed their investigation into the polarized radio emission in the galactic plane. The atlas is based on observations...

WASHINGTON, May 11, 2011 /PRNewswire-USNewswire/ -- The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA's Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The nebula is the wreckage of an exploded star that emitted light which reached Earth in the year 1054. It is located 6,500...
