NASA’s new video from the Hubble Space Telescope showed us two galaxies from far away that are in the process of merging or colliding with each other. It will take millions of years until the process finishes, though.
The galaxies are called NGC 2207 and IC 2163, and the team from Hubble discussed in their 48-second video about the two spiral galaxies that each has a nucleus, making the two galaxies resemble a “striking set of eyes.”
The Two Eyes Will Merge into a ‘Cyclops’
The Discovery of the collision was possible with the help of Hubble telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, all of them providing different images in infrared and x-ray, helping the scientists realize that the galaxies are gradually colliding.
The galaxies are 80 million light-years away from our planet. NGC 2207 is an intermediate spiral galaxy, and larger than the IC 2163, which is a barred spiral galaxy. It will take several millions of years for the collision to take place and alter the shapes of the objects. UPI has written that in the end, the galaxies will no longer look like a pair of eyes, but like a “cyclops”.
The collision has already given birth to “super star clusters”, which is space dust, marking the beginning of galactic collision. This collision will produce more space objects, baby stars, so the feature is called “stellar nursery”.
In 2014, NASA shared a photo of the same galaxies, stating that in the last 15 years, there were three supernova explosions, creating “one of the most bountiful collections” of shiny traces spotted by the Chandra X-ray Observatory.
Other Galaxies Have Been Seen Colliding
This new video shared by the Hubble team comes a few days after a study published in the journal Nature studied two other galaxies that are also starting to collide. They are 400 million light-years away from our planet. The ongoing collision of these far away galaxies could slow down the appearance of new stars, said the study. That’s because the collision has started forming a nebula, and the butterfly wing shape could be the cause.
