Europe team uses ALMA telescope to conclude the creation of galaxies

Astronomers from Europe have witnessed gas clouds that can form stars from the early universe. These clouds represent building blocks for the 1st galaxies. This is a remarkable 1st for the entire scientific community.

The ALMA telescope at the European Southern Observatory in Chile made this discovery when scientists were looking deep into space past galaxies to spot a faint glow from ionized carbon as per a report by UPI.

During this time, astronomers were attempting to catch a glimpse of a few of the oldest galaxies in this universe which date back to ask much as 800 million years post the Big Bang. This is when they spotted the glowing carbon signal alongside galaxy BDF 3299.

An astronomer and co-author of this study, Andrea Ferrara from Cuola Normale Superiore in Italy said that this was the furthest detection of an emission like this as per the report. This will allow scientists to look at galaxies while they are in just their early development stages.

Scientists currently believe that gas clouds filled space when time began. And when stars started forming out of these gas clouds and the dust started clearing in a process they call reionization.

Researchers now believe that they’ve spotted such dust just before collapsing into various stars using the ALMA telescope. It was spotted next to BDF 3299 since newly formed stars had cleared all the dust from the galaxy’s center.

This is a huge deal for scientists since they’ve been trying very hard to understand this interstellar medium & how stars & galaxies are formed.

Reionization is basically a term used in cosmology to help describe the process of matter reionizing in the universe. This is considered the second among 2 transitions for gas. The 1st phase involves the hydrogen change in the universe. This process is known as recombination.
