Mexican Telescope Discovers Earth-Sized Exoplanet
Mexican telescope and int. team find a 2nd Earth-sized planet orbiting ultracool dwarf star. Unlike TRAPPIST-1 system, this one is a solo act. The harsh environment likely makes it unlivable, but discovery hints at variety in these strange star systems.
With the Swiss-Mexican SAINT-EX telescope at the National Astronomical Observatory of San Pedro Mártir (Baja California) of the UNAM, scientists from this university participated in the discovery of the second exoplanet the size of the Earth, which revolves around an ultra-cool dwarf star.
Yilen Gómez Maqueo Chew, Laurence Sabin and Ilse Plauchu-Frayn, from the Institute of Astronomy, collaborated in the discovery of SPECULOOS-3b, with observations made in 2021 with SAINT-EX and followed up the work using the SPECULOOS network in 2022 and 2023.
