Scientists discover Milky Way's youngest exploding star-英语点津

Download Scientists have announced the discovery of the youngest known exploding star, or supernova, in our Milky Way galaxy. Astronomers using NASA's Chandra X-ray Observatory and the Very Large Array radio telescope in New Mexico have discovered the remains of a supernova, known as "G1.9", which must have lit up our galaxy with a bright flash of light about 140 years ago. Reynolds explains that scientists have measured the rates of exploding stars in other galaxies, and found out that our own Milky Way galaxy seems to be lagging behind in the number of supernovae per century. "Large spiral galaxies like the Milky Way seem to have two or three per century," he said.
