James Webb Telescope

NASA’s largest and most influential space science telescope, the James Webb Space Telescope (JWST), has made the groundbreaking discovery of a planet 99 percent the size of Earth. It is located in the Octans constellation and is 41 light-years away from our home planet.

The newly discovered exoplanet LHS 475 b is classified as. Little is known about its atmosphere and whether it is habitable for humans. The researchers have ruled out a thick methane-dominated atmosphere like Saturn’s Titan but say atmospheric compounds like pure carbon dioxide have not been ruled out.

A newly discovered space object is classified as an exoplanet because it orbits another star and has a terrestrial surface, such as a rocky planet made of silicate rocks or metals. As Daily Mail reports, it completes the orbit in two days.

Talking to the press, Mark Clampin, Astrophysics Division director at NASA Headquarters in Washington, DC, said that the find opens the door “to many future possibilities for studying rocky planet atmospheres with Webb.” He remarked that the telescope “brings us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started.”
