A comet gets destroyed by the sun, data centers endanger the Potomac River, and more science news

NASA released images of a newly discovered comet breaking apart after a close solar pass, highlighting the value of solar-observation data.

American Rivers named the Potomac River the most endangered river in the U.S., citing sewage leaks and rapid data center expansion.

The roundup also included new Artemis II coverage and an ESA Mars image, reflecting ongoing momentum in space exploration and imaging.

The Potomac warning underscores how aging infrastructure and data center growth are increasing pressure on a critical river basin.
