Answer : 1. "नासा"
Explanation :

Recently NASA has identified a possible “super-Earth” TOI-715 b, located 137 light years away. This distant planet orbits a small, red star within the conservative habitable zone, which suggests the possibility of liquid water. TOI-715 b is 1.5 times wider than Earth, completes an orbit in just 19 days, and may also have a companion Earth-sized planet. NASA's findings suggest surface water conditions in addition to atmospheric factors. This unprecedented discovery opens the way for further investigation of extraterrestrial life.
