This delicate tapestry of X-ray light is the remnant of a supe | ASTRONOMY
This delicate tapestry of X-ray light is the remnant of a supernova explosion that would have been witnessed on Earth about 3,700 years ago. Known as "Puppis A," it spans more than 100 light-years from side to side and it's located about 7,000 light years from Earth. Happy #FirstDayOfFall!
