Always learning something new,pretty cool discovery.


(BBC)-Scientists find a black hole in an unusual location - inside a compact group of ancient stars known as a globular cluster

Astronomers say the discovery is interesting because many doubted black holes could exist in such locations.

Some computer simulations had suggested a newly formed black hole would simply be ejected from the cluster as a result of gravitational interactions.

It was made using the European Space Agency's XMM-Newton satellite, with follow-up observations on the US space agency's Chandra Space Telescope - both are sensitive to the X-ray light that is emitted when gas consumed by a black hole is torn apart.

The international team says its work provides the first convincing evidence that some black holes might not only survive but grow and flourish in globular clusters

What has astonished the scientists is how quickly the black hole was found.

The black hole is located in a globular cluster associated with a galaxy named NGC 4472, some 55 million light-years away.

The black hole is located in a globular cluster associated with a galaxy named NGC 4472, some 55 million light-years away.

These high densities should lead to frequent interactions and even collisions; and some models have suggested that large black holes - several hundred times the mass of our Sun - could develop in the densest inner regions of clusters.

The team is uncertain about the size of the NGC 4472 hole; but if it is reasonably large - and one interpretation of the X-ray data suggests it could be 400 times the mass of our Sun - it might have been able to anchor itself in the cluster, said co-author Arunav Kundu of Michigan State University, US.
