James Webb's New Cumnor Planet Discovery Software Observing exoplanets is one of the most complex tasks of space telescopes. The reason is that the light of the planets orbiting the stars is lost in the blinding brightness of the stars. Now, in a new study published in the journal Nature, researchers have developed software for the James Webb Space Telescope that makes this task easier. This proposed method increases the probability of such planets being discovered by the James Webb Space Telescope. The software has now revealed a new view of a known giant planet that was hidden in the James Webb Telescope data. Researchers say they are using the telescope's built-in tool to remove most of the star's glow from James Webb's images. By blocking much of the starlight, this tool prevents it from entering the picture and quite simply, they create an artificial solar eclipse. Even so, a small amount of glare from the star still passes through this instrument, and for this reason, to overcome this problem, astronomers also photograph one or more similar stars, called reference stars, and then subtract their measured glare from the new image.
