A Harvard-led team detects escaping helium around super-Earth LHS 1140 b, the first confirmed atmosphere found on a rocky world in a habitable zone.

JWST observations of 29 Cygni b point to disk accretion, with carbon- and oxygen-rich signatures and a spin-aligned orbit that argue against star-like collapse.

The NSF-DOE Vera C. Rubin Observatory in Chile has activated its real-time astronomical alert pipeline, flagging 800,000 transient objects on its first operational night and setting the stage for a decade-long survey expected to catalog more objects than every previous optical telescope combined.

A 15-hour JWST observation has produced the first three-dimensional map of Uranus's ionosphere, confirming decades-long atmospheric cooling and exposing how the planet's tilted, offset magnetic field sculpts complex auroral structures unlike any seen elsewhere in the solar system.

CDG-2, a near-invisible galaxy 300 million light-years away, is the first detected solely through its globular cluster population. Roughly 99% of its mass is dark matter.
