The Brightest Explosion Ever Seen

This image shows the protocluster around the Spiderweb galaxy (formally known as MRC 1138-262), seen at a time when the Universe was only 3 billion years old. Most of the mass in the protocluster does not reside in the galaxies that can be seen in the centre of the image, but in the gas known as the intracluster medium (ICM). The hot gas in the ICM is shown as an overlaid blue cloud. Credit: ESO/Di Mascolo et al.; HST: H. Ford

Astronomers Witness The Birth Of A Very Distant Cluster Of Galaxies From The Early Universe

The Hubble Space Telescope’s Wide Field Camera 3 revealed the infrared afterglow (circled) of the BOAT GRB and its host galaxy, seen nearly edge-on as a sliver of light extending to the burst's upper right. This composite incorporates images taken on Nov. 8 and Dec. 4, 2022, one and two months after the eruption. Given its brightness, the burst’s afterglow may remain detectable by telescopes for several years. The picture combines three near-infrared images taken each day at wavelengths from 1 to 1.5 microns.

Carbon vs. iron abundance of extremely metal-poor (EMP) stars. The colour bar shows the probability for mono-enrichment from our machine learning algorithm. Stars above the dashed lines (at [C/Fe] = 0.7) are called carbon-enhanced metal-poor (CEMP) stars and most of them are mono-enriched. CREDIT Hartwig et al.
