JWST Cosmic Web, Exoplanet Atmospheres & Habitability
Key Questions
What did COSMOS-Web reveal about galaxies?
The survey mapped 164,000 galaxies, providing new insights into cosmic structures in the early universe.
What atmospheric findings has JWST made on exoplanets?
JWST confirmed salty clouds on GJ 504b and is studying terminator chemistry on WASP-121 b along with other targets like TRAPPIST-1e.
What new spectral features did JWST detect in Tc 1?
JWST identified previously unseen buckyball C60 bands in the near-infrared that eluded Spitzer observations.
How is JWST contributing to Europa research?
It has detected CO2 on Europa and is examining panspermia hypotheses alongside pre-supernova pressure mapping.
What updates exist on K2-18b biosignatures?
JWST data has prompted a re-evaluation of potential biosignatures on the sub-Neptune K2-18b.
What did JWST observe in the Cigar Galaxy?
The telescope captured images of 16.5 million stars, revealing detailed stellar populations.
Are there findings on dormant supermassive black holes?
JWST has weighed dormant SMBHs and followed up on Alpha Centauri planet candidates.
What galaxy mergers has JWST identified?
It has observed at least six galaxies merging to form one of the largest galaxies in the early universe.
COSMOS-Web maps 164k galaxies. JWST confirmed salty clouds on GJ504b. Also: TRAPPIST-1e stellar contamination; K2-18b biosignature re-evaluated; WASP-121 b terminator chemistry; dormant SMBH weighed; Alpha Centauri planet candidate follow-up; CO₂ on Europa; pre-supernova pressure mapping; panspermia hypothesis for Europa; buckyball C60 bands in Tc 1. New: JWST caught 6 galaxies merging into a brightest cluster galaxy 12 billion years ago; resolved 16.5 million stars in M82; observed galaxy-killing wind stripping gas from a young galaxy.
