[edit] Summary

Description

Composite of Chandra X-ray and VLA Radio Images The most recent supernova in our Galaxy has been discovered by determining the age of the supernova remnant known as G1.9+0.3. To determine the age, astronomers tracked how quickly it is expanding, by comparing a radio image from 1985 (blue) to a Chandra image taken in 2007 (orange). The expansion rate was confirmed with another radio observation with the VLA in 2008. The difference in size between the composite images gives clear evidence for expansion, allowing the age of the remnant and the time since the original supernova explosion (about 140 years) to be estimated.
