Scientist says that our Milky Way may have a sibling. However, the Milky way was shredded and devoured by a large galactic neighbor. Which is the closest among everywhere? The Andromeda Galaxy. Which apparently took place around two billion years ago.
What does science say about the Milky Way?
The Milky way which has been shredded mostly. Has left behind a trail of evidence. Which they say is an almost halo of stars. Which is more significant than Andromeda Galaxy itself. And also a separate compact galaxy M32.
As per scientist, the Galaxy was third-largest members of the local group of galaxies. Which has been disrupted? Which comes after Milky Way and Andromeda Galaxies.
Rebuild the Sibling of Milky Way.
Using a computer model Richard D’Souza and Eric Bell of the University of Michigan in the U.S. Together they were able to put the prices of evidence together. Which revealed the long-lost sibling of the Milky Way. Before this, the scientist had known that the mostly invisible halo of stars. Which were surrounding galaxies contained the remaining of smaller Galaxies?
A galaxy like Andromeda has not only destroyed this one. But it is expected by scientists that it may have destroyed and devoured many small companions of its. Due to which researchers thought it would be difficult to learn about any of those.
Scientist found that many small galaxies were consumed. Most of the stars which are on the faint outer halo of Andromeda. Is there because of shredding of smaller companies of Andromeda.
What does the scientist say?
D’Souza, lead author of the study published in the journal Nature Astronomy. Said,
For then it was a ‘eureka’ moment. When they realized that they could use this information of Andromeda’s outer stellar halo to infer the properties of the largest of these shredded galaxies.
Many Astronomers have been studying the local group. Which included Milky Way, Andromeda and many more. However, for them, it was shocking to know that Milky Way had a larger sibling. And the most shock comes as they had never known about this. This study has changed the traditional understanding of Galaxies evolve.
