New Software Improves Webb Telescope’s Exoplanet Imaging

Researchers have released a new software package that refines the physical model of the James Webb Space Telescope, enabling more accurate correction of subtle variations in the telescope’s configuration and pointing. By better modeling the point spread function, the tool reduces noise that has historically limited the effectiveness of coronagraphs used to block starlight. The result is a clearer, low‑noise image of exoplanets, allowing scientists to detect fainter planets and study their atmospheres with greater precision. The software also speeds up data processing, making it easier to analyze the growing catalog of exoplanets. This advancement could accelerate the characterization of distant worlds and improve the efficiency of future exoplanet surveys.
