There are nine massive stars, together 30 million times brighter than our sun, sitting out in the universe.

A team of astronomers spotted a cluster of stars about 170,000 light years from Earth. Together they are the largest group of very massive stars ever spotted, and were seen through the Hubble Space Telescope.

The new find could bring new findings about how huge stars develop. Scientists also said that it was a worthwhile demonstration of the powers of the Hubble Space Telescope, which is ageing and is less powerful than new telescopes that are to be launched in coming years.

The cluster is just a few light years a cross, and sits in a satellite galaxy of our Milky Way. But in that relatively small space is a huge range of massive, hot and luminous stars spitting out huge amounts of ultra violet light.
