‘Supernova factory discovered’

Astronomers have discovered seven supernovae in a galaxy nearly 250 million light years away from earth, confirming the belief that the universe’s most efficient star factories are also supernova factories.

A team at Chalmers and Onsala Space Observatory in Sweden says that never before have so many supernovae been spotted at the same time in the same galaxy.
The astronomers used a worldwide network of radio telescopes in five countries, including Sweden, to be able to create extremely sharp images of the galaxy Arp 220. They observed around 40 radio sources in the centre of the galaxy.
These radio sources are hidden behind thick layers of dust and gas and invisible in ordinary telescopes.
