A planet’s escaping helium, a star’s hidden infrared rhythms, and a possible distant world in the WISPIT 2 system reveal how much we can learn by watching light across the spectrum. New observations also trace the changing radio and X-ray activity of young V1298 Tauri, while detailed models map cloudy and clear regions across the hot Jupiter WASP-43 b.

Image: Tiny wobbles of a bright star HD 73344 have revealed the mass of a nearby sub-Neptune exoplanet
Additionally, another signal hints at the presence of a previously undetected planet orbiting farther from the star. HD 73344 is an F-type star approximately 115 light-years away. At roughly 20% larger than our Sun, it hosts a sub-Neptune exoplanet with a density similar to Saturns. The possible second planet has been detected with a minimum mass around one-third that of Jupiter...
