CAPE CANAVERAL, Florida: Astronomers finally know why the supernova was first documented large.

The exploding star was observed by the ancient Chinese in 185, visible for eight months. Later it was discovered that a supernova remnant larger than expected, 8,000 light years away.

New infrared observations show that the explosion took place in a cavity in space. The cavity allows stellar shrapnel to shoot faster and farther into the universe.

The star – similar to our sun – died in peace and became a dense white dwarf. He sucked the material from another star, and then exploded in a supernova.

NASA announced its findings Monday. Four space telescopes were used in the study.
