The birth of the first stars

A small team led by Alan Rogers and Judd Bowman used a simple radio antenna to detect signals from the first stars in the universe, surpassing the capabilities of the Hubble Space Telescope. Their work involved overcoming significant challenges, such as filtering out noise from our galaxy. After years of refinement, they confirmed their discovery, which was larger than expected, suggesting colder early universe conditions. This finding opens new avenues for research into the universe's evolution and the role of dark matter.
