Galaxy-Size Bubbles Discovered Towering Over the Milky Way

January 6, 2021

For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option.

The Search for Dark Matter Is Dramatically Expanding

November 23, 2020

Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.
