However, the scientists have been able to rule out the presence of certain elements, including methane.

It’s orbit is so close that the planet is able to complete a full circuit of its relatively cool parent star once every two Earth-days.ĭespite the quality of the JWST data, the team aren't yet sure whether or not the newfound world plays host to an atmosphere. The frequency of the light dips from the parent star also revealed that LHS 475 b travels around its star in an incredibly tight orbit - closer even than the path that the innermost planet of our solar system, Mercury, treads around our Sun. The initial results from the flagship telescope confirmed the presence of a rocky exoplanet with a diameter 99% that of Earth, in orbit around the red dwarf. Following the initial discovery, the JWST was tasked to observe the distant star on August 31 last year. One such light signature was detected from a red dwarf star orbiting within the Milky Way 41 light-years from Earth in the constellation Octans. TESS was designed to take in a wide-angle view of the cosmos in order to watch out for tiny, periodic dips in the light of distant stars that could indicate the presence of an orbiting exoplanet passing between the telescope and its stellar guardian. The candidate world - known as LHS 475 b - was first identified by NASA’s Transiting Exoplanet Survey Satellite (TESS). Now, astronomers have made the first confirmed discovery of a new exoplanet using the keen golden eye of the JWST.
