What Happens if Dark Matter Goes Missing? NASA’s Hubble Has the Answer

Dark matter makes up for a large part of the universe and it basically refers to particles that do not absorb, reflect, or emit light. This is why they cannot be detected by looking at electromagnetic radiation.

The particles we divide in the universe are either visible matter or dark matter. But what if Dark Matter disappears? Strange as it may sound, in 2018, scientists were stunned when there was no dark matter in a neighboring galaxy. The official Instagram handle of the Hubble Telescope recently shared the story on stage, explaining how Hubble’s data solved the mystery.

It is understood that dark matter is an important component for the evolution of galaxies but it was not only in the galaxy NGC 1052-DF4. A year later, another galaxy that recalled dark matter was discovered, called NGC 1052-DF4 and surprised scientists more than ever. Now, data collected by the Hubble Telescope revealed why Dark Matter was missing.

Miria Montes of the University of New South Wales in Australia led an international team of astronomers to study the galaxy using deep optical imaging. They found that the effects of tidal disintegration could explain the missing dark matter. According to a Report good By NASA, “The gravitational forces of the neighboring giant galaxy NGC 1035 are stripping NGC 1052-DF4. During this process, dark matter is removed, while the stars feel the effects of contact with another galaxy at a later stage. “

Hubble was used to study the galaxy’s distribution of spherical clusters to obtain the light and physical properties of the galaxy.

By studying the light of the galaxy, astronomers came to the evidence of the tidal tail, which was formed due to material moving away from NGC 1052-DF4. Since dark matter is less concentrated than the stars, it was moved away from the galaxy and thus disappeared.
