TL;DR

Astronomers have potentially detected the rainbow-like "glory effect" on the distant exoplanet WASP-76b, 637 light-years away, using data from ESA's Cheops satellite and other missions. This delicate phenomenon, previously observed only on Venus, could provide insights into the nature of this ultra-hot gas giant and its nearby star. The discovery suggests the presence of perfectly spherical atmospheric particles and stable temperatures, offering valuable lessons for understanding distant worlds and aiding in the detection of critical phenomena in exoplanets.
