Data from the DESI (Dark Energy Spectroscopic Instrument) Legacy Imaging Surveys have revealed over 1200 new gravitational lenses, approximately doubling the number of known lenses. Discovered using machine learning trained on real data, these warped and stretched images of distant galaxies provide astronomers with a flood of new targets with which to measure fundamental properties of the Universe such as the…

Gravitational lenses could hold the key to better estimates of the expansion of the universe
The universe is expanding but astrophysicists aren’t sure exactly how fast that expansion is happening—not because there aren’t answers, but rather because the answers they could give don’t agree. Source: https://phys.org/news/2020-11-gravitational-lenses-key-expansion-universe.html…
