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.
