Dozens of newly discovered gravitational lenses could reveal ancient galaxies and the nature of dark matter

Earlier this year a machine learning algorithm identified up to 5,000 potential gravitational lenses that could transform our ability to chart the evolution of galaxies since the Big Bang. Now, astronomers have assessed 77 of the lenses using the Keck Observatory in Hawai'i and Very Large Telescope in Chile. The team confirmed that 68 out of the 77 are strong gravitational lenses spanning vast cosmic distances.
