The Very Large Telescope's (VLT) Multi-unit spectroscopic explorer [wikipedia.org] (MUSE) has been used to study the galaxies in the Hubble Ultra-Deep Field [wikipedia.org]. It has also revealed previously unseen galaxies [earthsky.org]:

Sometimes, astronomy is about surveying widely to get the big picture. And sometimes it's about looking more and more deeply. First released in 2004, the Hubble Ultra Deep Field [spacetelescope.org] is clearly about going deep. It's a composite image of a tiny region of space, located in the direction of the southern constellation Fornax, made from Hubble Space Telescope data gathered over several months. There are an estimated 10,000 galaxies in the Hubble Ultra Deep Field, which exist as far back in time as 13 billion years ago (between 400 and 800 million years after the Big Bang). Being able to see galaxies so near the beginning of our universe has been a fantastic tool for understanding how the universe has evolved. And now – thanks to an instrument called MUSE (Multi Unit Spectroscopic Explorer), astronomers have been able to eke out yet more information – a veritable bonanza of information – from the Hubble Ultra Deep Field. Their work is being published today (November 29, 2017) in a series of 10 papers in a special issue [aanda.org] of the peer-reviewed [aanda.org] journal Astronomy & Astrophysics.
