Observations made with the James Webb Space Telescope (JWST) have revealed a larger-than-expected number of massive galaxies when the Universe was still young. The focus of this study is precisely one of these galaxies, ZF-UDS-7329. It is a very compact object, and its spectrum suggests that it formed at a very early stage, when the Universe was around 2 billion years old. According to theoretical predictions, these objects first formed a generation of stars at the center of their dark matter halos and subsequently grew by merging with other halos. However, due to the random nature of theseAdvertised on -

Astronomers at the Instituto de Astrofísica de Canarias (IAC), using the 2-meter robotic Two-meter Twin Telescope (TTT) at the Teide Observatory, have obtained the deepest optical images ever taken of Malin 2, one of the largest and faintest spiral galaxies in the Universe. These ultra-deep observations have revealed previously unseen structures, including several diffuse stellar emissions and a striking, elongated spiral-like feature, hinting at past interactions with other galaxies. The team has also identified a potential ultra-diffuse dwarf galaxy (UDG) about 400,000 light-years fromAdvertised on
