VISTA helps astronomers pinpoint when the first massive galaxies were born

Astronomers have used the European Southern Observatory’s VISTA telescope to discover hundreds of previously undetected massive galaxies. The findings are localized to a small patch of sky, and their discovery provides clues as to when such objects first emerged in the early Universe.

All 574 galaxies are located in a single patch of sky that appears around four times the size of a full Moon – a region VISTA has been focused on for some six years. ie. the findings are not “localised” in the sense of anisotropy, that just happens to to where they decided to point the telescope.
