Astronomers have discovered young analogs of the Milky Way

Astrophysicists from the United States, India and the United Kingdom discovered young analogs of the Milky Way. The corresponding study is published in the journal Science, briefly reported by the University of California at Santa Cruz.

The galaxies ALMA J081740.86 + 135138.2 and ALMA J120110.26 + 211756.2 are located at a distance of 12 billion light years from the Earth. Scientists managed to find out how these galaxies were arranged 300 million years after the Big Bang.

ALMA J081740.86 + 135138.2 and ALMA J120110.26 + 211756.2 are surrounded by massive hydrogen clouds. The disks of galaxies revolved, which indicates that they are the precursors of giant spiral systems, to which the Milky Way belongs.

The rate of star formation in ALMA J081740.86 + 135138.2 and ALMA J120110.26 + 211756.2 was moderate – from 25 to 100 solar masses per year.

The scientists were able to study the properties of galaxies with the help of the ALMA (Atacama Large Millimeter Array) radio telescope complex, located in Chile. Experts plan to discover in the next few years new young analogs of the Milky Way. This should help to understand the origin of the Galaxy.
