Dude, this Atacama Cosmology Telescope (ACT) stuff is absolutely insane. These guys basically hit "rewind" on the universe and managed to see light from when it was only 380,000 years old! To put that in perspective, the Big Bang happened about 13.8 billion years ago, so that’s like 99.99% of the way back. Almost like a save point from the beginning of everything.

Astronomers operating the powerful Atacama Cosmology Telescope (ACT) in Chile have used the observatory’s unmatched abilities to “time travel” and view the universe during a period 99.99% of the way into its ancient past.

Although previous telescopes have looked deep into the past by observing light from a few million years after the Big Bang, an event most models estimate at around 13.8 billion years ago, the research team utilizing the ACT observed light from only 380 thousand years after the Big Bang.
