spectroscopy

NASA's James Webb Space Telescope has characterized the atmosphere of TOI-199b, a Saturn-sized world 330 light-years away—the first temperate giant exoplanet studied in detail.

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.

Rice University physicists built magnetoARPES, a new instrument that revealed the first direct momentum-space evidence of time-reversal symmetry breaking in the kagome superconductor CsV3Sb5, confirming theoretically predicted loop current orders.
