Galaxy: Complete Guide: The Moment Two Galaxies Collide in a Super Rare

This guide provides a clear overview of galaxy, including the main concepts, practical steps, and common questions. Use it to understand the topic, compare the available options, and make a more informed decision.

Galactic mergers can happen over millions of years, meaning astronomers have the perfect opportunity to observe and study the phenomenon while it's happening.

Such a moment was captured by NOIRLab's Gemini North telescope in Hawaii, providing a beautiful and precious image. The image shows two galaxies NGC 4568 and NGC 4567 in a dramatic process of collision and merger. The two are now just 20,000 light-years apart, and they're poised to enter a destructive yet captivating phase of fusion.

The two galaxies are located about 60 million light-years away towards the constellation Virgo, and both are spiral galaxies similar to our own Milky Way. However, as they get closer together, the massive gravitational flows involved in the merger will begin to distort the two, triggering bursts of star formation in certain regions.

'When NGC 4568 and NGC 4567 merge, their gravity will begin to 'duel' and trigger powerful star-forming explosions, violently distorting the massive structure of both. For millions of years, the galaxies will continuously cycle through each other in an increasingly tight direction, creating long bands of stars and gas until their individual structures are completely mixed to the point of becoming into a single, essentially spherical galaxy. By that time, most of the gas and dust (the fuel for star formation) in this system has either been used up or blown away'.

The same scenario will happen with our Milky Way when it collides with neighboring galaxy Andromeda over a period of about 4 billion years.
