This “embrace” of two black holes allows us to study how our own galaxy might end

The Milky Way’s fate is to merge with Andromeda, and this collision of black holes millions of light-years away mirrors our fate.

Imposed rise at the center of great galaxies black holes, Understanding how they work has been one of the most important puzzles in recent years, and a cause of insomnia for thousands of astronomers around the world. Despite being very close, I very milky waya recent discovery 500 million light years Very important information has been revealed to us that we apply to our scary and dark “neighbors”.

A group of scientists has discovered an astronomical marvel in Crab: Merger of two black holes. scientists used Atacama Large Millimeter/Submillimeter Array (spirit) and nasa technology (Hubble Telescope) to detect UGC4211, the name given to this pair of black holes. These two giants are “very” close to each other, only 750 light years away, so it is estimated that they will end up colliding in a few hundred million years. None of us will live to see it, but when it does, a massive new galaxy will form around us. A newborn “super black hole”,

A mirror that allows us to see the fate of the Milky Way

These two stars are massive, and it is estimated that their mass is 125 to 200 million times that of the surface of the Sun. The study that revealed its impending merger They used a wide range of tools to study them, and this is how study co-author Ezequiel Traester explained it:

“Ground-based optical images showed us the entire merging galaxy, Hubble showed us atomic regions in high resolution, and ALMA showed us the precise location of these two hungry and growing supermassive black holes. All these data together gave us a picture of It is clear that galaxies like ours came out as they are and what they will become in the future”.

In his words, one of the most revealing aspects of this discovery remains unspoken, and is the relationship with which he the fate of our own galaxy, The Milky Way has an end date, and the most recent studies estimate it to be around 4.5 billion years. When that day comes, our galaxy will collide with Andromeda, causing A fusion as we have seen in UGC 4211Although in this case on a smaller scale.

This “hug” of galaxies we’ve discovered millions of light-years away could help us understand the final stages of the mysterious process of two black holes merging, and gravity load that produces such an event. This is something that will eventually affect us, and generate a new galaxy from the Milky Way and Andromeda, headed by a new and massive black hole.
