The clearest image yet of Betelgeuse's long-suspected companion could help explain the star's changing brightness.

A private spacecraft failed to rescue the aging Swift space telescope, leaving it to re-enter Earth's atmosphere with timing and location uncertain.

Light from a magnetar with an extremely powerful magnetic field shows signs of a quantum vacuum birefringence effect predicted by Heisenberg 90 years ago.

A massive ice island has detached from Petermann Glacier after years of growing fractures, with two more huge sections expected to follow.

Glacier loss in the Alps could break the 2022 record, raising risks of falling river levels and deadly ice avalanches.

Reduced oxygen at higher elevations could prevent insects from moving upslope to escape warming, threatening pollination and other services.

Corals that partner with heat-tolerant algae survive warming oceans better but face an unexpected trade-off of higher disease susceptibility.

JWST observations of 72 young sun-like stars reveal that forming planets must assemble quickly before disk material dissipates.

The gravitational-wave background may preserve clues about the universe's first supermassive black holes, possibly descended from hypothetical dark stars.

The ASTRID simulation uses JWST data to help astrophysicists probe how black holes and galaxies co-evolved across cosmic time.
