Astronomers just discovered 72 never-before-seen galaxies using the Multi Unit Spectroscopic Explorer (MUSE) instrument on the ESO’s Very Large Telescope (VLT)in Chile as part of the deepest spectroscopic survey ever conducted.
These galaxies are all located in a relatively small area of space known as the Hubble Ultra Deep Field (HUDF). Over the last decade, this area has been the target of a wealth of observation, but it wasn’t until scientists were able to look at it using MUSE that these 72 galaxies became visible. This is because these galaxies are Lyman-alpha emitters, meaning they only shine brightly in one color of light.
Hubble’s Deep Field keeps on surprising
