46 ASTRO PUBLISHING The most distant galaxy candidate yet by ALMA Observatory Bárbara Ferreira T hree-color image of HD1, the most distant galaxy candidate to date, created using data from the VISTA telescope. The red object in the center of the zoom-in image is HD1. [Harikane et al.] A n international astronomer team has discovered the most distant galaxy candi- date to date, named HD1, which is about 13.5 billion light-years away. This discovery implies that bright sys- tems like HD1 existed as early as 300 million years after the Big Bang. This galaxy candidate is one of the James Webb Space Telescope (JWST) tar- gets launched late last year. If obser- vations with the JWST confirm its exact distance, HD1 will be the most distant galaxy ever recorded.
