Cosmic collision. Turned the Magellanic Clouds into chaotic.

"The Small Magellanic Cloud (SMC) is a nearby dwarf galaxy and one of the Milky Way’s closest companions. Rich in gas but relatively low in heavy elements, it provides astronomers with an important laboratory for studying how stars form and galaxies evolve.

“The Small Magellanic Cloud, or SMC, is one of the Milky Way’s nearest galactic neighbors. It is a small, gas-rich galaxy visible to the naked eye from the Southern Hemisphere, and it remains gravitationally linked to our galaxy along with its companion, the Large Magellanic Cloud, or LMC.” (ScitechDaily,A Cosmic Crash Turned This Nearby Galaxy Into Chaos)

“The SMC contains more mass in gas than in stars. Under normal conditions, gas cools and contracts due to gravity. It forms a rotating disk, similar to the process that created the flat, spinning structure of our solar system. However, earlier measurements using the Hubble Space Telescope and the European Space Agency’s Gaia satellite showed that the SMC’s stars are not moving in an orderly rotation around the galaxy’s center.”(ScitechDaily,A Cosmic Crash Turned This Nearby Galaxy Into Chaos)

“A study published in The Astrophysical Journal offers a possible answer. Researchers from the University of Arizona found that the SMC’s lack of stellar rotation likely stems from a direct collision with the LMC. This discovery also raises concerns about using the SMC as a model for understanding galaxy evolution over cosmic time.” (ScitechDaily,A Cosmic Crash Turned This Nearby Galaxy Into Chaos)

The Small Magellanic Cloud (SMC) is a gas-rich dwarf galaxy located near the Milky Way. That galaxy is one of the closest galaxies around the Milky Way. That object is near another irregular dwarf galaxy: the Large Magellanic Cloud (LMC). The inconsistent form of those galaxies caused discussions. The reason for their interesting form was the collision between the SMC and LMC. 

This collision turned those galaxies. Into chaos. That chaos is interesting because that means those galaxies collided so close in the past that they had no time to reorder their structures. In the same way. When Andromeda hits the Milky Way. That causes chaos. When the Andromeda galaxy. Close.  Milky Way. First, it should travel past our galaxy. It starts to orbit the Milky Way following a spiral-shaped trajectory. 

That closing spiral trajectory causes the collision between the Andromeda Galaxy’s supermassive black hole. And the Sagittarius A, the supermassive black hole in the center of the Milky Way. That collision happens in the distant future. The calculated time to that collision is 4-5 billion years. So, when that happens, the Sun is turned into a white dwarf. 

“The Magellanic Clouds (Magellanic system or Nubeculae Magellani) are two irregular dwarf galaxies in the southern celestial hemisphere. Orbiting the Milky Way galaxy, these satellite galaxies are members of the Local Group. Because both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies.” (Wikipedia, Magellanic Clouds)

The two galaxies are the following:

“Large Magellanic Cloud (LMC), about 163 kly (50 kpc) away.”

“Small Magellanic Cloud (SMC), about 206 kly (63 kpc) away.”

Previously, astronomers believed that those galaxies. They were old ones. The gas-rich structure of the SMC caused suspicions about the age of those galaxies. And modern observations. Tell that the cosmic collision turned those galaxies into chaos. Normal spiral and elliptical galaxies form around the mass center. Those mass centers are normally supermassive black holes. 

That thing turns the galaxy into a spiral structure around that supermassive center. The lack of a mass center turns galaxies into inconsistent. Or chaotic forms. Another thing that can turn a galaxy. Into chaos is the cosmic collision. The question is how that chaos affects the star formation in the galaxy? In modern models, stellar formation requires whirls in the material re. Those whirls start to form the denser points in gas and dust. 

Those material packs start to accumulate material around them. Do those whirls form stars? It depends on how long the material accumulation can keep its form. If some cosmic event, like a supernova explosion, happens too close, that thing can destroy the proto-star before anybody even knows its existence. Also, chaotic form. And crossing material flows can destroy those proto-stars.
