Beautiful remnant of a Supernova

Take a look at the image. This stunning image was captured by the Hubble Space Telescope. The red patch on the picture denotes the remnant of a supernova, caused by a massive steller explosion that was recorded more than 1000 years ago. This image measures five million light years across and shows the expanding blast waves.

Astronomers first detected a faint optical emission from the supernova remnant back in 1976. They worked out that the shock wave from the explosion had expanded at a rate of nearly 20 million miles per hour. Presently, this red patch has a diameter of nearly 60 light-years and is expanding at a rate of about six million miles per hour.
