A curated list of other prominent stories from this day.
Researchers propose that black holes do not evaporate completely and instead leave tiny remnants that retain the information of what fell in. They argue the same underlying seven dimensional geometry could also connect to why elementary particles have mass.
11:12 PMScienceDailyNASA says solar activity has dragged the aging Swift Observatory into a faster orbital decay, raising the risk of an uncontrolled reentry as soon as this year. An emergency rendezvous attempt is underway using Katalyst Space Technologies' Link spacecraft to intercept Swift and change its trajectory.

NASA's Hubble captures a star-spangled sea of 500,000 stars
Summary
NASA released a detailed Hubble portrait of Messier 3, a globular cluster containing more than 500,000 stars. Scientists use its unusual stars and possible merger origin to reconstruct parts of the Milky Way's assembly history.
Why it matters
If M3 traces a merger, it becomes a clean marker for when the Milky Way grew by swallowing smaller galaxies.

Scientists may have finally solved the black hole information paradox
Summary
Researchers propose that black holes do not evaporate completely and instead leave tiny remnants that retain the information of what fell in. They argue the same underlying seven dimensional geometry could also connect to why elementary particles have mass.
Why it matters
Resolving the paradox would remove a core inconsistency between quantum mechanics and gravity and reshape how physicists model black holes as quantum systems.

NASA launched an emergency mission to stop the Swift Observatory from crashing to Earth
Summary
NASA says solar activity has dragged the aging Swift Observatory into a faster orbital decay, raising the risk of an uncontrolled reentry as soon as this year. An emergency rendezvous attempt is underway using Katalyst Space Technologies' Link spacecraft to intercept Swift and change its trajectory.
Why it matters
It tests whether commercial servicing can prevent hazardous reentries and keep critical science assets operating despite accelerating orbital decay from solar storms.
