Visualisation of galaxies from the ESO GOODS spectroscopic campaign

The Great Observatories Origins Deep Survey (GOODS) project unites the world’s most advanced observatories, including ESO’s Very Large Telescope (VLT), to make extremely deep observations of the distant Universe, across the electromagnetic spectrum. GOODS gives us a unique view of the formation and evolution of galaxies across cosmic time, by observing two deep fields in the sky. Astronomers used spectrographs on the VLT to capture the spectra of galaxies in the southern GOODS field, spreading out the colours of their light like a rainbow. This let them measure the redshift of their light, and hence how distant they are. An extensive campaign produced redshifts for almost 3000 galaxies. With this knowledge, we can place the galaxies at distances along a vast cone of space, as shown in this visualisation, stretching out from our own vantage point like a searchlight beam into deep space. We can take an amazing journey through a tunnel towards the edge of the Universe. In some places, the galaxies cluster together, forming structures which are up to tens of millions of light years in scale.
