Webb received the first stellar photons, Hubble was looking for brown dwarfs, and astronomy was buzzing


Aha, this is the latest image taken by NASA’s Hubble Space Telescope, and it’s just gorgeous.In this image, Hubble captured one of three parts that make up a 65-light-year-wide star-forming region called the Chamaeleon Cloud Complex.This Hubble Mosaic image of a region known as Chamaeleon Cloud I (Cha I) reveals dusty clouds inside the primordial disk structure, dazzling reflective nebulae of bright blue young stars, and clusters of radiant interstellar gas known as Herbig Haro objects.Herbig Haro was excited by jets of young protostars during its formation, and the white-orange cloud at the bottom of the image is carrying one of the protostars at its center.Its bright white jets of hot gas erupt from the poles, forming the Herbigharo object HH 909A.Hubble is now looking for and studying very dark, low-mass brown dwarfs, “failed stars” that range in size between a large planet and a small star (10 to 90 times the mass of Jupiter) and are not massive enough to ignite and sustain nuclear fusion in their cores.A recent Hubble search uncovered six new low-mass brown dwarf candidates, data that could help astronomers better understand these objects.The 315-megapixel Mosaic is made up of 23 observations from Hubble’s Advanced Survey Camera.Twenty wide-field and Second Wide-field Planetary Camera images filled in the gaps between these observations, with ground-based data from ESO’s VISTA VIRCAM filling in the remaining gaps.
