SUMMARY: A new image from the Chandra X-Ray Observatory shows a trail of black holes and neutron stars that stretch into space for fifty-thousand light years. Astronomers believe that these objects are the evidence that two galaxies collided a few billion years ago. When the galaxies collided, material from the smaller galaxy was pulled into long tidal tails which created new areas of large star formation. Over millions of years these large stars evolved into black holes and neutron stars which are visible in the X-ray spectrum.

That must be a new born star that die in a supernova...and collapse (below 3 Mass of the sun) and turn into a black hole.
