Galaxy with Impossible Light Signature

This region of space, viewed first iconically by Hubble and later by JWST, shows an animation that switches between the two. Both images still have fundamental limitations, as they were acquired from within our inner Solar System, where the presence of zodiacal light influences the noise floor of our instruments and cannot easily be removed. The extra presence of point-like red objects in JWST images, also known as “little red dots,” has finally been explained, but other puzzles still remain.






Since its launch in December of 2021, the James Webb Space Telescope (JWST) has spotted record-setting objects all across the Universe, including at the greatest distances ever seen.

Many distant galaxies are energetic and show signatures of emission lines from specific atoms and molecules, particularly hydrogen. However, the Lyman-α line has never been seen earlier than 550 million years after the Big Bang.

Until now. With the discovery and spectroscopic follow-up on galaxy JADES-GS-z13-1-LA, we now have strong evidence for that emission line from a galaxy just 326 million years after the Big Bang. The question is: how?              READ MORE...
