In theory, there are thousands of black holes in our galaxy. Astrophysicists have now discovered a dozen black holes near the centre of the Milky Way, and just three light years away from the galaxy's supermassive black hole, Sagittarius A*. Scientists reckon that there are another ten thousand in the region:
"This finding confirms a major theory and the implications are many," said Dr. Chuck Hailey, at Columbia University in America. The study is published in the journal NATURE.
Meanwhile, astronomers using the Subaru telescope in Hawaii and the Issac Newton telescope on the Canary Isles, have produced one of the largest 3D maps of the early universe and discovered 4000 new infant galaxies.
Using "look-back-time", scientists at Lancaster University mapped 16 different stages of the Universe, between 11 billion and 13 billion years ago, to discover the early galaxies. Many of these galaxies have evolved into galaxies like the Milky Way.
The discoveries were made public at the European Week of Astronomy and Space Science in Liverpool on April 3rd.

Dear Brian
Perhaps I should not get involved in discussing issues I do not properly understand.
ie I should just sit back and accept all "supposed" astronomical discoveries (arguably I am wrong to even use the word "supposed" about things I don't understand.
However, as I think I've said before, I think cosmology is advancing too rapidly. This is in my opinion at least partly because of the over-use of modern technology (eg computers).
My comments might be hypocritical because I use my own computer arguably too much for several things. In some respects computers have made some my interests such as photography much more enjoyable than old fashioned "celluloid film" film technology.
To stop waffling on too much, I'll just say that I sometimes think cosmologists risk extrapolating half proved discoveries too much and extrapolating extrapolations might be dodgey.
Best wishes from Cliff
