How Milky Way Is Different From All Other Galaxies! Know Here

With the advancement in the field of science and technology, various theories and revelations surfaced the news and database. Our galaxy, which is home to Earth and its solar system, might not be as “typical” as previously thought, and therefore Milky Way-based models to understand other galaxies of the universe could be misleading, says the recent research.

The lead author of the paper published in the Astrophysical Journal, Marla Geha of Yale University in the US has said, “We use the Milky Way and its surroundings to study absolutely everything.

She added, “Hundreds of studies come out every year about dark matter, cosmology, star formation, and galaxy formation, using the Milky Way as a guide. But it’s possible that the Milky Way is an outlier.”

It is very well believed that the Milky Way is host to several dozens of smaller galaxy satellites, they orbit around the Milky Way and are useful in understanding the Milky Way altogether.

Amidst this, the results from the Satellites Around Galactic Analogs (SAGA) Survey, supported by the US National Science Foundation indicate that the Milky Way’s satellites are much more tranquil than other systems of comparable luminosity and environment. Many satellites of those “sibling” galaxies are actively pumping out new stars, but the Milky Way’s satellites are mostly inert, claims the reports.

According to the researchers, this is a significant result as many models for what we know about the universe rely on galaxies behaving in a fashion similar to the Milky Way. This exclusive survey- SAGA has begun five years ago with a goal of studying the satellite galaxies around 100 Milky Way siblings.

As of now, the details of eight other Milky Way sibling systems are studied.
