Super-Earth Discovered In The Habitable Zone Of TOI-715
The discovery: A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away. The same system […]

JWST/NIRCam Transmission Spectroscopy Of The Nearby Sub-Earth GJ 341b
We present a JWST/NIRCam transmission spectrum from 3.9−5.0 μm of the recently-validated sub-Earth GJ 341b (RP=0.92 R⊕, Teq=540 K) orbiting a nearby bright M1 star (d=10.4 pc, Kmag=5.6).
