"I think we are just starting to scratch the surface of what is possible with JWST," Jacob Lustig-Yaeger, an astronomer at the Johns Hopkins University Applied Physics Laboratory in Maryland and one of the lead authors of the study, told reporters on Wednesday at the 241st meeting of the American Astronomical Society in Seattle.Webb's design process began when scientists had identified only a handful of exoplanets, and the observatory wasn't tuned to discover alien worlds.
At the time, LHS 475b was just a candidate, not a confirmed planet. But it only took two transits of the exoplanet in front of itsfor Webb to detect it, living up to its fame of being the largest and most powerful space observatory to date."These pristine data help to validate and confirm the discovery of this Earth-size exoplanet," Lustig-Yaeger added.
