April Flowers for redOrbit.com - Your Universe Online NASA's Space Shuttle Columbia carried the Chandra X-ray Observatory into space 15 years ago, deploying it on July 23, 1999. Chandra, along with the other "Great Observatories" like Hubble and Spitzer, has helped to revolutionize the way we view the Universe using an unprecedented X-ray vision. "Chandra changed the way we do astronomy. It showed that precision observation of the X-rays from cosmic sources is critical to understanding...

Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed
2014-06-02 10:03:18

Brett Smith for redOrbit.com - Your Universe Online Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small-scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space, according to a new report in the journal Nature Physics. "Magnetic fields are ubiquitous in the universe," said study author Don Lamb, a professor in astronomy and astrophysics at the University...

Hardy Star Survives Supernova Blast
2014-03-21 05:24:03

[ Watch the Video: What Is A Supernova? ] NASA When a massive star runs out of fuel, it collapses and explodes as a supernova. Although these explosions are extremely powerful, it is possible for a companion star to endure the blast. A team of astronomers using NASA’s Chandra X-ray Observatory and other telescopes has found evidence for one of these survivors. This hardy star is in a stellar explosion’s debris field − also called its supernova remnant − located in an HII...

WASHINGTON, Feb. 18, 2014 /PRNewswire-USNewswire/ -- NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet - the longest of any object in the Milky Way galaxy -- of high-energy particles. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the...

Legacy Of The X-ray Universe Preserved With Chandra Data Archive
2013-10-30 07:05:30

NASA Every year, October is designated as American Archive Month. While many people may think “archive” means only dusty books and letters, there are, in fact, many other types of important archives. This includes the use of archives for major telescopes and observatories like NASA’s Chandra X-ray Observatory. The Chandra Data Archive (CDA) plays a central role in the mission by enabling the astronomical community – as well as the general public – access to data collected by...

How Fast Does A Supernova Shockwave Travel? A Japan Team May Have The Answer
2013-08-13 14:51:55

Brett Smith for redOrbit.com - Your Universe Online Some of the most spectacular explosions this side of the Big Bang, supernovae generate unthinkable amounts of force and energy and new research from Keio University in Japan has measured the expansion velocity of a supernova shockwave for the first time. The shockwave measured by the research team was from the supernova remnant W44, which is located approximately 10,000 light years from Earth. Quantifying the expansion and kinetic...

Chandra Discovers Supernova Remnant Emission Is Synchrotron Radiation
2013-06-26 16:32:40

Lee Rannals for redOrbit.com – Your Universe Online Astronomers will be reporting details about a supernova remnant known as G1.9+0.3 in the upcoming issue of The Astrophysical Journal Letters. In 2008, a team of scientists discovered the remains of a supernova known to have occurred in the Milky Way, about 28,000 light years away from Earth. The explosion would have been visible from Earth a little more than a hundred years ago, assuming it was not obscured by dust and gas....

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...

Young Supernova Remnant Discovered By NASA’s Swift Satellite
2013-03-16 10:18:20

redOrbit Staff & Wire Reports — Your Universe Online NASA´s Swift space observatory detected the previously undiscovered remains of a supernova during an extensive X-ray survey of the Milky Way, officials from the US space agency announced on Friday. NASA believes the shattered star remains, which have been named G306.3—0.9 after the coordinates of its sky position, are among the youngest-known supernova remnants in the galaxy. “Astronomers have previously...

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

Michael Harper for redOrbit.com — Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for...
