Two NASA Satellites Collaborate to Capture Galactic Mergers



The Milky Way is our home. and the existence of all human beings treated us well The Earth and our solar system are relatively relaxed here in one of the galaxy̵

7;s curved arms. Live our day to day in peace At least in cosmic terms, however, fast forward 4.5 billion years and we may begin to see galaxies change. At that point, the Milky Way is expected to begin colliding with the nearby Andromeda Galaxy.

If a collision between two galaxies sounds rather ferocious. And luckily for us, we don’t have to wait 4.5 billion years to see it in action. The galactic system, called Arp 299, consists of two galaxies at the center of the merger, and NASA used the Chandra X-Ray Observatory in conjunction with the Hubble Space Telescope to capture images of cosmic vibrations. that made it truly mouth-watering.

As NASA explains in a new blog post, Arp 299 is a merger of two galaxies that have been merging for quite some time. The speed at which galaxies travel through space relative to other objects can vary greatly — Andromeda is moving toward the Milky Way at nearly 70 miles per second. Based on the best data we have — but even galaxies are moving very fast. fast on paper Its sheer size means it can take hundreds of millions or even billions of years to merge.

In the case of the Arp 299, we have no way of knowing exactly when the collision first occurred or how long the merger continued. The system is approximately 134 million light-years from Earth, so our observations of the event are delayed by 134 million years. The two galaxies have certainly collided throughout human history. and maybe even life still exists on our planet

Scientists have made various estimates about how long galaxies gather when they collide. There are many factors that can change the timeline. including the size of the respective galaxies and the angle at which the two galaxies meet. Estimates vary. But it is generally accepted that this process takes at least a few billion years. and may be longer depending on the conditions

The most interesting thing about galaxies merger is that Even though it sounds very scary But it is unlikely that the individual stars in these systems will actually collide. Some of them may affect each other due to gravity. but in general The stars and planets remain largely unaffected, even in the long run.

In the case of Andromeda and the Milky Way Our solar system and the Sun should have survived the test unharmed. It will be so hot that the world’s oceans will simmer for a long time. And there is no life left on Earth at all. The planet may still be here at that point, but we as a species certainly will not be.
