exoplanets

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.

Webb found Beta Pictoris d by reading its atmosphere's chemical fingerprint, a first for exoplanet discovery, while a separate imaging study independently confirmed it.

ESA's Euclid Q2 release maps 4.8 square degrees of the galactic bulge, previewing Roman's 2027 exoplanet survey.

NASA has set a firm August 30 launch date for the Nancy Grace Roman Space Telescope, eight months ahead of schedule, as the observatory is packed for its barge trip to Kennedy Space Center.

A CNRS-led team used the VLT's SPHERE instrument to watch a protoplanetary disk spin, finding anomalies linked to forming giant planets.

An ESO and Gemini North team found winds on seven hot Jupiters slow as the planets get hotter, a pattern best explained by planet-wide magnetic fields.

Astronomers used JWST's MIRI to directly study the surface geology of LHS 3844 b, a super-Earth 48.5 light-years away, revealing a basaltic, atmosphere-free world resembling Mercury — a first for exoplanet science.

A University of Warwick team applied a new machine-learning pipeline called RAVEN to four years of TESS observations, statistically validating 118 short-period planets and surfacing roughly 1,000 candidates not previously catalogued.

A Princeton-led reanalysis of 83.7 million TESS light curves used random forest classifiers to surface 11,554 planet candidates, including one confirmed hot Jupiter, by reaching stars 16 times fainter than prior searches.

The TOI-201 system hosts a super-Earth, a warm Jupiter, and a record-setting brown dwarf whose gravitational interplay drives orbital shifts observable on human timescales — within 200 years its planets will stop transiting.

A new JWST MIRI observation of the 12-light-year-away exoplanet Epsilon Indi Ab shows less ammonia than models predict, pointing to thick water-ice cirrus clouds that current atmospheric models omit.

NASA publicly revealed its completed Roman Space Telescope on April 21 at Goddard, setting up a Falcon Heavy launch as early as this fall for a five-year survey of dark energy, exoplanets, and the galactic bulge.
