Last week, Nancy Atkinson posted on Universe Today that astronomers are now understanding why they’ve missed 90% of the observable galaxies, and, with new tools, are now able to see them.
Here’s a paragraph from Atkinson’s article:
“Astronomers have long known that many surveys of distant galaxies miss 90% of their targets, but they didn’t know why. Now, astronomers have determined that a large fraction of galaxies whose light took 10 billion years to reach us have gone undiscovered. This was found with an extremely deep survey using two of the four giant 8.2-meter telescopes that make up ESO’s Very Large Telescope (VLT) and a unique custom-built filter. The survey also helped uncover some of the faintest galaxies ever found at this early stage of the Universe.”
