Astrophysicists discover youngest known supernova in Milky Way

This artist's impression shows a view looking down on the Milky Way galaxy. The position of the Sun is shown, as are the approximate positions and names (shown in orange) of historical supernovas. These are stellar explosions that are thought to have occurred in the last 2,000 years and may have been seen by early astronomers. The estimated position of the recently discovered G1.9+0.3 is shown in black. Although the distance to this remnant is uncertain, the angle is accurately known. Note that G1.9+0.3 is the only object that is found in the bulge of the galaxy. Credit: NASA/CXC/M. Weiss
