Millions of years after the Big Bang, some stars formed. And they are to known to be what first brought light into the universe. These stars formed right after the “dark ages”- which by the way is the time after the Big Bang but before there was any light, where the universe was filled with just dark gas. Astronomers found these very first stars by using a radio telescope out in Western Australia.

Radio telescopes are cool because they are able to detect radio waves, which are the longest wavelength known to exist in our universe, meaning it can detect stuff that’s traveled great distances to get to us. Based on changes detected in the Cosmic Microwave Background Radiation, astronomers were able to create models suggesting that 180 million years after the Big Bang, these first stars formed.

This adds to previous research, and now we are lead to believe that these first stars were probably massive blue stars, and based on the spectral classifications of stars we know that blue stars are, massive, hot, young, short-lived stars, that die naturally by a supernova explosion or a collapse of its core into a black hole. By using instruments at the Murchison Radio Astronomy Observatory, astronomers picked up dips in the frequency received from the early universe, and this represents the moment that stars first formed and began interacting with the matter around them.

Not only can this lead us into a better understanding of our early universe, and its evolutionary stages, but according to the scientists, this could possibly be the work of cold dark matter particles pulling energy away from the hydrogen gas and cooling it down. This is all speculation of course, since we still don't have confirmation of dark matter existing, but this new info could help. It will be fascinating to see what more research there is to come out of this finding, because early universe understandings means getting closer to finding the meaning of life.
