Summary
DescriptionG19 xray.tif |
English: G1.9+0.3 is the remains of the most recent supernova, in Earth's time frame, known to have occurred in the Milky Way. If gas and dust had not heavily obscured it, the explosion would have been visible from Earth just over a century ago. A new long Chandra observation - equivalent to over 11 days of time - reveals new details about the explosion.

Image title | A new Chandra observation is providing important details about the most recent supernova known to have exploded in the Milky Way. The explosion would have been visible from Earth a little more than a hundred years ago if it had not been heavily obscured by dust and gas. G1.9+0.3 was most likely created when a white dwarf star underwent a thermonuclear detonation and was destroyed - either after merging with another white dwarf or by pulling too much material from an orbiting companion star. The Chandra data show that most of the X-ray emission is "synchrotron radiation," produced by extremely energetic electrons accelerated in the rapidly expanding blast wave of the supernova. The new X-ray study also reveals that the explosion that created G1.9+0.3 was asymmetrical and unusually energetic. |
