🪐 The James Webb Space Telescope has revealed that the star-forming galaxy JWST-UNCOVER-z13, seen as it was just 330 million years after the Big Bang, contains surprising traces of oxygen. Detecting this element so early suggests that the first generations of massive stars lived brief, violent lives—creating and spreading elements vital for the formation of later stars, planets, and possibly life itself. ✨ #galaxies⚡#cosmicmysteries⚡#webb⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The galaxy MACS0647-JD is among the most distant objects ever observed by the Hubble Space Telescope—its light started traveling toward us about 13.3 billion years ago, when the universe was less than 4% of its current age. Seeing MACS0647-JD allows scientists to peer back to the era when the very first galaxies began to form, offering a glimpse into the universe's ancient youth. ✨ #galaxies⚡#distances⚡#cosmicmysteries⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
