Astronomers have detected helium escaping from the atmosphere of LHS 1140 b, a rocky super-Earth located about 50 light-years away in a habitable zone. Because the exoplanet possesses roughly six times the mass of Earth, its immense gravity creates an escape velocity that likely makes launching spacecraft physically impossible with current rocket technology. This extreme gravitational pull has sparked engaging discussions about the limitations of spaceflight on super-Earths and the potential implications for the Fermi paradox.
