Astronomers have mapped the architecture of the exoplanetary system TOI-3884 by capturing rare planet transits that crossed over dark starspots. Using MuSCAT3 and MuSCAT4 instruments on Las Cumbres Observatory's 2-meter telescopes, the team observed three transits in early 2024 and detected strong spot-crossing signals. The multicolor data revealed spot temperatures roughly 200 K cooler than the
