Astronomers working with the Very Large Telescope in Chile have surveyed a patch of the sky and detected 72 new galaxies never seen before.
What's new: Beginning in 2004, the Hubble Space Telescope delivered detailed pictures of a patch of sky that now bears its name — the Hubble Ultra-Deep Field is a view nearly 13 billion years back into the early universe. Using the Multi Unit Spectroscopic Explorer (MUSE) instrument, researchers again looked at this well-studied region and found 72 new galaxies and collected more information about 1,600 of the estimated 10,000 galaxies there. (The existence of the new galaxies needs to be confirmed, possibly by the James Webb Space Telescope when it launches next year.)
