New Research Says that Early Galaxies Could be Sending us Neutrinos

This image shows 15 of the 341 hitherto identified “little red dot” galaxies discovered in the distant Universe by JWST. These galaxies all exhibit similar features, but only exist very early on in cosmic history; there are no known examples of such galaxies close by or at late times. Credit: D. Kocevski et al. (2025)

Those "Little Red Dots" discovered by the James Webb Space Telescope, galaxies that existed during the very early Universe, could be sending neutrino particles that are reaching us today.
