Collision Between Two Galaxies Captured

By Aazam

The European Southern Observatory (ESO)'s Very Large Telescope (VLT) in Paranal, Chile has obtained a spectacular image of the collision between two galaxies that led to the formation of the giant galaxy NGC 7727.

Individual stars usually do not collide because the distance between them is much greater than their size, but galaxies can collide.

Gravity is accompanied by tidal forces that dramatically change the form of nearby galaxies as they dance around each other.

You can see that two bright dots are also visible in the center of the galaxy inside the image, which is another telltale sign of its dramatic past.

Under the core of NGC 7727, the core consists of two galactic cores, each of which continues to host a supermassive black hole.

It is believed to be the closest pair of supermassive black holes ever found, located about 89 million light-years from Earth in the constellation of Aquarius.

The two black holes, which are about 1,600 light-years apart, are destined to be contained in an even more massive black hole, which is expected to merge within 250 million years.
