Here’s What’s Causing Star Formation In The Milky Way

Collisions or mergers between galaxies are a part of cosmic evolutions,, and astronomers are very well aware of this. Mergers are causing galaxies to grow, but another effect is that they also trigger new rounds of star formation.

This is due to the fact that fresh gas and dust are injected into the galaxy.

Milky Way and Andromeda will merge 

Astronomers have been estimating that the Milky Way galaxy and Andromeda will merge one day and also the Small and Large Magellanic Clouds.

Universe Today reveals that according to new results obtained by researchers at the Flatiron Institute’s Center for Computational Astrophysics (CCA) in New York city, it seems that the results of the merger with the Magellanic Clouds are currently being felt.

The results presented at the 235th meeting of the American Astronomical Society show that the stars that are forming in the outskirts of our galaxy could be the result of the dwarf galaxies that are merging with Milky Way.

The online publication mentioned above notes that data from the ESA’s Gaia observatory unveiled the “existence of a young stellar cluster in the outskirts of the Milky Way’s halo. This cluster has been designated Price-Whelan 1 in honor of the team leader Adrian M. Price-Whelan (a research fellow with the CCA).”

The stream of gas is closer to Milky Way than it was believed

It’s been also revealed that spectra obtained from the cluster show that they formed from the stream of gas that was extending from the galaxies is much closer to the Milky Way that is was previously believed.

Identifying star clusters in our galaxy is not the easiest thing since stars may appear to be clustered in the sky, but in reality, they are separated by massive distances. More than that, stars may even be in the proximity of each otheer at one point, but then they could find themselves moving in other directions.
