Today an image was taken in space revealing a collision between the cores of two merging galaxies. Both of these were powered by a black hole with millions of times the mass of the sun. Recently, the cores of these galaxies have been approaching each other at tremendous speeds and will soon experience a final cataclysmic collision. It is estimated that these two galaxies will crash into in a few million years. This amount may seem large to us, but in fact is a short period on a galactic timescale. Also, since these two galaxies are interacting, a lot of dust and gas has been swept up forming a burst of new stars that give off infrared light.
This is important because it displays an example of unique movement of the galaxies that is caught during a rare phase of their evolution.

1. Good detial from actual article
ReplyDelete2. To the point
3. Explains the effects of the two galaxies colliding and the impact it will have in space
1. Could have said where or how far away from earth this is happening
2. Could have explained if or any effect this event will have on humans or other life
1. I learned that two galaxies are going to collide in a few million years creating new stars
