Meet G1.9+0.3, the youngest supernova in the Milky Way that has ever been found. б This imageб is a combination of a radio image from the NRAO’s VLA taken in 1985 and an x-ray image taken from NASA’s Chandra X-ray telescope taken in 2007.
In 2008, the age of G1.9+0.3 was estimated at around 140 years. б This makes it about 200 years younger than Cassiopeia A which was previously the youngest supernova in the Milky Way. б G1.9+0.3 was not visible from Earth due to space dust and gas that obscured the view.
G1.9 +0.3 is approximately 25,000 light-years away from Earth. б At 140 years old, it should probably hold the title of youngest supernova in our galaxy for quite a long time.
