“We’re witnessing a new era as skies fill with thousands of bright satellites,” said Meredith Rawls, a research scientist with the Vera C. Rubin Observatory and the DiRAC Institute at the UW. “In just the last two years, astronomers have realized this will impact our ability to achieve science goals from ground-based facilities like Rubin Observatory.”

Nine years ago today, an asteroid exploded over Chelyabinsk, Russia. It was only about 20 meters in diameter (or 55-65 feet) — by meteor and asteroid standards, pretty small, but as you may remember, it packed a punch.

The Bernardinelli-Bernstein comet is named after its discoverers, University of Washington postdoctoral scholar Pedro Bernardinelli, and University of Pennsylvania cosmologist Gary Bernstein, who first spotted the comet in the Dark Energy Survey dataset.
