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....

A new image from NASA's Chandra X-ray Observatory shows a supernova remnant with a different look. This object, known as SNR 0104-72.3 (SNR 0104 for short), is in the Small Magellanic Cloud, a small neighboring galaxy to the Milky Way. Astronomers think that SNR 0104 is the remains of a so-called Type Ia supernova caused by the thermonuclear explosion of a white dwarf. In this composite made of X-rays from Chandra shown in purple and infrared data from Spitzer shown in green and red, SNR 0104...

Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. Their new data provides evidence that this remnant is from a type Ia supernova - the explosion of a white dwarf star - and raises questions about the ways in which magnetic fields affect the generation of the remnant's cosmic ray particles. NC State physicists Dr. Stephen...

The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy. The supernova explosion occurred about 140 years ago, making it the most recent supernova in the Milky Way as measured in Earth's time frame. Previously, the last known galactic supernova occurred around 1680,...
