“The Milky Way Swallows Galaxies” Discovered the remains of a galaxy inside the Milky Way

The Gaia spacecraft has spotted the remnants of an ancient cosmic collision in the Milky Way, revealing a previously unknown galaxy.

The Milky Way absorbed the unknown "Pontos" galaxy, attracted and destroyed it about 10 billion years ago.

"Events such as this merger are important for learning about the Milky Way, because they show the (family tree) of the smaller galaxies that helped make our galaxy what it is today," the European Space Agency said in a statement.

The statement added: "The motions of stars and other objects close to us, in turn, will reveal insights about the formation, formation and evolution of the Milky Way," according to the "Space" website, which specializes in space news.

The exciting scientific discovery was made by studying the Milky Way's halo, a region filled with globular clusters of ancient stars and those with low-frequency minerals.
 
The European Space Agency explained that "when a foreign galaxy falls into our region, great gravitational forces known as tidal forces separate them. If this process proceeds slowly, the stars from the merging galaxy will form a broad stellar stream that is easily discernible in the corona. process quickly,the stars of the merging galaxy will be more scattered throughout the corona and will not be visible."

Stars are not the only way we can detect a compact galaxy, if the intruder contains globular stars or small satellite galaxies, they may also appear in the halo of the Milky Way.
