MUSE revealed 72 galaxies never seen before in this very tiny area of the sky. These galaxies are all located in a relatively small area of space known as the Hubble Ultra Deep Field (HUDF).

The astronomers conducted the deepest spectroscopic survey ever using the MUSE instrument on ESO’s Very Large Telescope in Chile. This portion of sky had already been observed, but it wasn’t until scientists were able to look at it using MUSE that these 72 galaxies became visible. This open a new debate for other life forms and for planets similar to the Earth.
