Like virtually every other galaxy in the universe, the Galaxy NGC 4845 has a central black hole.

We even get to see a (relative) close-up of a "barred spiral galaxy" (above) called NGC 1365.

In the galaxy NGC 1277, astronomers have discovered a black hole with the mass of 17 billion suns.

Measurements undertaken with two space-based X-ray telescopes imaged the black hole at the centre of galaxy NGC 1365.
It just so happened that while they were doing so, NGC 4845 was in their field of view.

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

Based on information from the GALEX program, astronomers have crowned spiral galaxy NGC 6872 the largest known spiral galaxy in the universe.
In the distant galaxy NGC 5806, astronomers using the Hubble Space Telescope have observed a supernova that happened 80 million years ago.
This supermassive black hole lies at the center of galaxy NGC 1277, which is about 220 million light years away from Earth.

As a result of its interaction with IC 4970, one of the arms of NGC 6872 looks likes it may be spinning off to form its own dwarf galaxy.
That interaction increased the size of NGC 6872, and also produced new star forming regions where stars much younger than the other stars in the two galaxies are now being born.
Astronomers using the Hubble Space Telescope have discovered a supernova in the distant galaxy NGC 5806, which is a relatively unremarkable galaxy located about 80 million light years from Earth.
Galex - a space telescope designed to search for the ultraviolet light that newly born stars put out - hinted that NGC 6872 was made much larger in size by the collision.
Over the course of the next few hundred million years, the two black holes in NGC 6240, which are about 3, 000 light-years apart, will drift towards one another and merge to form an even larger supermassive black hole.
At a distance of about 400 million light-years, NGC 6240 is a prime example of a massive galaxy in which stars are forming at an exceptionally rapid rate due to a recent collision and subsequent merger of two smaller galaxies.
