have we ever seen galaxies collide?
Google is your friend:Sobhan said:have we ever seen galaxies collide?
Google "bullet cluster"newjerseyrunner said:I'd be interested to know what the dark matter around the galaxies do when do of them come together.
There is a lot of heat generated by merging dust clouds. Suns and planets barely notice each other. I'd guess nothing anywere close to a supernova.Sobhan said:does the collision emit lots of energy like a supernova
A galaxy collision is a rare phenomenon in space where two or more galaxies come into close proximity and their gravitational forces cause them to merge.
Galaxy collisions are relatively rare events and are estimated to occur about once every few billion years. However, this can vary depending on the size and location of the galaxies involved.
When galaxies collide, their gravitational forces cause them to merge and form a new, larger galaxy. This process can also trigger the formation of new stars and can lead to changes in the structure and appearance of the galaxies involved.
While galaxy collisions may seem dramatic, they are actually relatively safe for the galaxies involved. This is because the distances between stars and other objects within galaxies are so vast that collisions between individual objects are unlikely to occur.
Scientists study galaxy collisions using various tools and techniques, including telescopes, computer simulations, and observations of the light and other forms of radiation emitted by the galaxies involved. By studying these collisions, scientists can better understand the formation and evolution of galaxies.
