TRIBUN-MEDAN.COM – Same as Milky Waythe Andromeda galaxy is also a spiral galaxy.
However, astronomers noticed that the area near the galactic center filled with stars looked different than it should have been.
The orbits of these stars are oddly shaped, oval, like someone stretching out a lump of Silly Putty, a toy made from a silicone polymer that has unusual physical properties.
It can bounce, but breaks when given a sharp blow, and can also flow like liquid.
A new study led by CU Boulder has solved a decades-old mystery surrounding this strangely shaped star cluster located at the heart of the Andromeda Galaxy.

The results of the study were published in the journal Astrophysical Journal Letters on October 29, 2021, entitled On the Formation of an Eccentric Nuclear Disk following the Gravitational Recoil Kick of a Supermassive Black Hole.
According to the study, explains that, this is due to the existence of a supermassive black hole at its core which releases a strong gravitational kick during a galactic collision, so strong, it can drop millions of stars into tilted orbits.
The first view of the Andromeda galaxy is thought to show a supermassive black hole surrounded by a relatively symmetrical cluster of stars.
However, they found a large, elongated mass. What caused it? Scientists may have found the answer.
Using the help of computer simulations, scientists tracked what happens when two supermassive black holes collide.
