#JWST reaches new milestone in quest for distant #galaxies.
The light from these galaxies has taken more than 13.4 billion years to reach us implying they existed 400 million years after the big bang, when the #universe was only 2% of its current age.
These galaxies are extremely faint because of their great distance from us. Astronomers can now explore their properties, thanks to JWST's exquisite sensitivity.

NASA's Webb reaches new milestone in quest for distant galaxies
An international team of astronomers has used data from NASA's James Webb Space Telescope to report the discovery of the earliest galaxies confirmed to date. The light from these galaxies has taken more than 13.Science X staff (Phys.org)

•"At some point around 200 to 500 million years, the *earliest* generations of stars and galaxies form (exact timings are still being researched), and early large structures gradually emerge, drawn to the foam-like dark matter filaments which have already begun to draw together throughout the universe."
So it's not just "old", it is actually damn close to "first". 😮
