By examining a cloud of exploded remains, NASA's Chandra X-ray Observatory has "carded" a supernova remnant to reveal its underage status. At a mere 140 years old, G1.9+0.3 is the youngest known supernova remnant in the Milky Way. The materials surrounding it are still expanding at almost 35 million miles per hour, an unprecedented speed for a supernova remnant.
