Cosmic Evolution Early Release Science Survey (CEERS) tagged posts

Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are published in the journal Nature.

Follow-up observations since first detection of Maisie’s galaxy have revealed that it is from 390 million years after the Big Bang...

Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.

The JWST appears to be finding multiple galaxies that grew too massive too soon after the Big Bang, if the standard model of cosmology is to be believed.

In a study published in Nature Astronomy, Mike Boylan-Kolchin, an associate professor of astronomy at The University of Texas at Austin, finds that six of the earliest and most massive galaxy candidates observed by JWST so far stand to contradict the preva...
