Notable Quotes

"We have peered into a new world and have seen that it is more mysterious and more complex than we had imagined. Still more mysteries of the universe remain hidden. Their discovery awaits the adventurous scientists of the future."

Galaxies must contain about ten times as much dark mass as can be accounted for by the visible stars.

Stories

The Rubin Observatory opens its eye on 20 billion galaxies

New Capabilities

Observatory namesake, pioneering dark matter researcher

On June 23, 2025, the Vera C. Rubin Observatory released its first images—and they're staggering. A 3.2-gigapixel camera, the largest ever built for astronomy, captured 10 million galaxies in a single frame. In just 10 hours of test observations, it found 2,104 asteroids nobody knew existed, including seven near-Earth objects. This isn't a telescope taking pretty pictures—it's a time machine that will photograph the entire Southern Hemisphere sky every three nights for a decade.

Fusion reactors as dark matter laboratories

New Capabilities

Provided observational evidence for dark matter in galaxies

Fusion reactors might crack open the dark matter mystery without trying. University of Cincinnati physicist Jure Zupan and colleagues at Fermilab, MIT, and Technion just published a breakthrough showing how neutrons slamming into reactor walls could spawn axions—the hypothetical particles that may explain the 27% of the universe we can't see. The twist: we're already building these reactors for clean energy.
