An article published in the journal “Nature” describes the discovery of a super-Earth called LHS 1140b. A team led by Jason Dittmann of the Harvard-Smithsonian Center for Astrophysics used the HARPS instrument installed on ESO’s 3.6-meter telescope in La Silla, Chile, to study that exoplanet after identifying it with the MEarth-South telescope at Cerro Tololo Inter-American Observatory. Its location in ​​its solar system’s habitable zone makes it particularly interesting.
