From the Andes to the Beginning of Time: Telescopes Detect 13-Billion-Year-Old Signal

Humans Have Now Seen the Dawn of Time from Earth After Breakthrough

🌘Subscribe to 404 Media to get The Abstract, our newsletter about the most exciting and mind-boggling science news and studies of the week. Scientists have captured an unprecedented glimpse of cosmic dawn, an era more than 13 billion years ago, using telescopes on the surface of the Earth. This marks the first time humans have seen signatures of the first stars interacting with the early universe from our planet, rather than space. This ancient…

From the andes to the beginning of time: Telescopes detect 13-billion-year-old signal

Astronomers have pulled off an unprecedented feat: detecting ultra-faint light from the Big Bang using ground-based telescopes. This polarized light scattered by the universe's very first stars over 13 billion years ago offers a new lens into the Cosmic Dawn. Overcoming extreme technical challenges, the CLASS team matched their data with satellite readings to isolate this ancient signal. These insights could reshape our understanding of the univ…

Astronomers see the 1st stars dispel darkness 13 billion years ago at 'Cosmic Dawn'

The CLASS telescope array has taken a fresh look at the infant universe to hunt for polarized light in the Cosmic Microwave Background that resembles light bouncing off a cosmic car hood.

'People thought this couldn't be done': Scientists observe light of 'cosmic dawn' with a telescope on Earth for the first time ever

For the first time, astronomers have used a ground-based telescope to observe polarized microwave light from the universe's earliest epoch. Their observations could give them a better understanding of how the universe evolved.

From the andes to the beginning of time: Telescopes detect 13-billion-year-old signal - Science Tech Updates

Small telescopes in Chile are first on Earth to cut through the cosmic noise. For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the Big Bang. Using telescopes high in the Andes mountains of northern […] The post From the andes to the beginning of time: Telescopes detect 13-billion-year-old signal appeared first on Science Tech Up…
