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.

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.

Two companion JWST studies confirm a spectrally resolved helium emitter with no detectable metals sitting 3 kiloparsecs from GN-z11, the strongest signature yet of Population III stars at redshift 10.6.

Webb telescope finds a Jupiter-sized planet orbiting a tiny red dwarf has fewer heavy elements in its atmosphere than its own star, defying all existing formation theories.

The first dual-coronagraph record of a Kreutz sungrazer's destruction and a pre-print tracing the comet's 1,663-year orbit to a daylight comet of 363 AD are reshaping models of cometary survival and the family's ancient genealogy.

The Kreutz sungrazer broke apart approximately six hours before reaching its closest point to the Sun on April 4, peaking at magnitude -0.6 in coronagraph imagery before its nucleus shattered. Only submicron dust debris emerged on the far side, leaving nothing visible from the ground.

NGC 1052-DF9 is the third ultra-diffuse galaxy found lacking dark matter in a linear trail near NGC 1052, lending significant support to the Bullet Dwarf collision theory and challenging alternative gravity models.

The farthest Kreutz sungrazer ever discovered will pass just 161,000 kilometers above the Sun's surface on Saturday, threading the inner solar corona in a make-or-break encounter that could produce a comet visible in broad daylight or end in total disintegration.

The fourth gravitational wave transient catalog adds 128 new detections from a nine-month observing run, including the heaviest and fastest-spinning black hole mergers ever recorded.

NASA's Hubble Space Telescope caught comet C/2025 K1 fragmenting into at least four pieces across three days, marking the closest-to-breakup observation in the telescope's history.

Using the upgraded GRAVITY+ instrument on the ESO's Very Large Telescope Interferometer, researchers have directly detected a second protoplanet forming in the disk around the young star WISPIT 2, located 437 light-years from Earth.
