Star Songs Plucked From The Cosmos
2013-06-01 05:44:51

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) have blended science, technology and art to create a unique new website that allows people to listen to original musical compositions crafted from cosmic x-rays. The Star Songs website was published by research associate Gerhard Sonnert, who worked with University of Glasgow postdoctoral student Wanda Diaz-Merced and composer Volkmar Studtrucker on the project....

NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Astronomy is more than merely using optical telescopes to take pretty pictures of distant nebulae and galaxies. Researchers also seek to understand complex systems in the universe by observing how objects interact and what types of radiation are produced. To do this requires telescopes capable of observing over several energy bands, working together to construct a complete physical picture of the object of interest....

Kepler Supernova Remnant Triggers Identified
2013-03-19 04:33:38

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory has identified the cause of Kepler's supernova, the famous explosion first discovered by Johannes Kepler in 1604. The image above shows low (red), intermediate (green) and high (blue) energy X-rays with a star field background from the Digitized Sky Survey. It is already known that the supernova is a Type Ia, which is the thermonuclear explosion of a white dwarf star. Type Ia's are important cosmic...

Astronomers Discover Youngest Black Hole In Milky Way
2013-02-13 12:11:40

Lee Rannals for redOrbit.com — Your Universe Online A rare explosion from a rotating star may have created the most recent black hole formed in the Milky Way galaxy. Astronomers using NASA's Chandra X-ray Observatory claim that matter was ejected at high speeds along the poles of a rotating star, creating a supernova remnant, W49B, which may contain a young black hole. "W49B is the first of its kind to be discovered in the galaxy," said Laura Lopez, who led the study at the...

New Chandra Footage Suggests Vela Pulsar May Be Precessing
2013-01-08 12:30:00

Watch the video "Chandra Captures Neutron Star In Action" redOrbit Staff & Wire Reports - Your Universe Online New video footage of the Vela pulsar, a neutron star located approximately 1,000 light-years from Earth, suggests that the pulsar could be slowly wobbling as it spins, NASA officials said on Monday. Formed following the collapse of a massive star, the Vela pulsar is approximately 12 miles in diameter and capable of making a complete rotation in under 90 milliseconds. 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...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

Chandra X-ray Observatory -- NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. The Observatory has three major parts: (1) the X-ray telescope, whose mirrors focus X-rays from celestial objects; (2) the science instruments which record the X-rays so...
