Since its launch in December 2021, the James Webb Space Telescope (JWST) has been breaking records.
with an estimated diameter equaling around 99 percent of Earth's) hinted that the planet was there, but now the high-resolution imagery offered by the Near-Infrared Spectrograph on board the JWST has confirmed it.
Despite the size similarity, the planet is thought to be much hotter than our own home world, circling a red dwarf star close enough to complete an orbit in just two days., from the Johns Hopkins University Applied Physics Laboratory in Maryland."Webb's pristine data validated it." This newly found object sits 41 light-years away in the constellation Octans, and has been given the designation LHS 475 b. As with other exoplanets, it was spotted by looking at the shadow created as it passes in front of its star.; the assortment of light wavelengths being filtered around the planet that can reveal qualities of its atmosphere.For now, we don't have enough data to tell us what kind of atmosphere LHS 475 b has, if it has one at all.
"These first observational results from an Earth-size, rocky planet open the door to many future possibilities for studying rocky planet atmospheres with Webb,""Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our Solar System, and the mission is only just getting started."
