Milky Way Black Holes Found By Astronomers
Astronomers have found two black holes, each up to 20 times heavier than the Sun, hidden deep inside our own galaxy.
The unexpected discovery was made by a team exploring a 12 billion-year-old cluster of stars in the Milky Way called M22.
It contains hundreds of thousands of stars and can be seen with the naked eye as a hazy patch of light.
Scientists at the International Centre for Radio Astronomy Research now believe there could be as many as 100 black holes inside the cluster.
Dr James Miller-Jones, who co-wrote a report that appears in the journal Nature, said: "Simulations of how globular clusters evolve show that many black holes are created early in a cluster's history.
"The many black holes then sink towards the middle of the cluster where they begin a chaotic dance. Most are thrown out until only one surviving black hole remains.
"We were searching for one large black hole in the middle of the cluster, but instead found two smaller black holes a little way out from the centre, which means all the theory and simulations need refinement."
Black holes are formed when a massive star reaches the end of its life and collapses in on itself.
They are so dense that even light cannot escape them.
The M22 cluster, which can be found in the constellation Sagittarius, was discovered almost 350 years ago.
It is 10,000 light years away, so astronomers on Earth only see it as it was 10,000 years ago.
The research involved scientists from the University of Southampton, as well as universities in the United States and Australia.

what do you think?
i wish i could understand most of theabove but it leaves me baffled .
being a photographer and having a go at taking photos of the night sky,i have done a little research and this find is really interesting and we are getting close to how the universe works.
It is fascinating - but not sure we're really that close to knowing "how the universe works"... just still refining our thinking with each new discovery, as we've always done..
well done, now perhaps you could try to find April Jones?
With a telescope? Don't be ridiculous.
It is mindblowing We live on a rock that orbits a star,just the right distance.any closer to the sun we would burn up, any further away we would freeze.planet earth seems to be the oddball in the known universe. Mankind has looked skyward for centuries and now with Hubble we can see things never seen before. Our galaxy alone is 100,000 light years across and there are millions of galaxy's is the universal infinite? ? The universe is a violent place. We are well overdue for a metor strike it has happened in the past it will.happened again the first time round it blew dust earth debris up into the atmosphere,sunlight couldn't reach the surface hence the dinosaurs were made extinct. We can see them coming now though one will narrowly miss earth in 2029.
