How Early Did the First Stars Form in the Universe After the Big Bang?

Astronomers have been in the process of acquiring important data on early signals from the universe shortly after the Big Bang in search of the earliest formation of large-scale structures in the cosmos, e.g., stars, galaxies, quasars, and so on.

In only 180 million years after the Big Bang, apparently, astronomers from Arizona State University (ASU), the Massachusetts Institute of Technology (MIT), and the University of Colorado at Boulder discovered important objects through the EDGES experiment or the Experiment to Detect the Global Epoch of Reionization Signature project.

They made the discovery with funding by the National Science Foundation. Thank you much, NSF, this is barely possible without you. The astronomers discovered a small window into the early universe at only T=180 million years, where they could see stars forming.

Arizona State University Astronomer Judd Bowman said, “Finding this miniscule signal has opened a new window on the early universe… Telescopes cannot see far enough to directly image such ancient stars, but we’ve seen when they turned on in radio waves arriving from space.”

The accepted models of the early Big Bang universe depict stars that were “massive, blue and short-live.” The Cosmic Microwave Background Radiation…
