The Hunt for Cosmic Dawn: HERA Doubles Sensitivity to Unlock the Secrets of the Early Universe - SciTechDaily
Feb 08, 2023 2 mins, 0 secs
An array of 350 radio telescopes located in the Karoo desert of South Africa is getting closer to detecting “cosmic dawn” – the time period following the Big Bang when stars first ignited and galaxies formed.

The telescope is only able to observe between April and September, when the Milky Way is below the horizon, because the galaxy produces a lot of radio noise that interferes with the detection of faint radiation from the Epoch of Reionization.

Looking at the sky with sensitive telescopes, astronomers have mapped in detail the faint variations in temperature from this moment — what’s known as the cosmic microwave background — a mere 380,000 years after the Big Bang.

The HERA team continues to improve the telescope’s calibration and data analysis in hopes of seeing those bubbles in the early universe, which are about 1 millionth the intensity of the radio noise in the neighborhood of Earth.
