  • A very cold and/or extremely reddened protoplanet in the disk around MWC 758 has been detected in images and with spectroscopy. MWC 758c is responsible for driving the disk’s spiral arm patterns. The protoplanet orbits at a projected separation of ~100 au and is one of the youngest giant planets known.

  • Simultaneous observations of TRAPPIST-1 b from JWST at 12.8 and 15 μm indicate that it is probably a bare rock with a mineral-rich surface. However, an alternative scenario with a CO2-rich atmosphere and hazes could also explain the observations.

  • The JWST MIRI transmission spectrum of WASP-107b, a transiting planet with Neptune-like mass and Jupiter-like radius, shows observations of sulfur dioxide and silicate clouds but no methane in its atmosphere, providing evidence of disequilibrium chemistry and active photochemistry.

  • Observations from the JWST MIRI showed the detection of 14NH3 and 15NH3 isotopologues in the atmosphere of a cool brown dwarf, along with a 14N/15N value consistent with star-like formation by gravitational collapse.
