The NOIRLab has released a detailed image of the sombrero galaxy, revealing its extensive stellar halo and star streams from past collisions. Meanwhile, astronomers have observed interstellar comet C/2025 R3 Pan-STARRS, which is passing through the solar system for the first time in 170,000 years, and the upcoming Lyrid meteor shower is expected to peak tonight, offering spectacular skywatching opportunities.
JWST limb-resolved spectroscopy reveals a cloudy morning limb and a clearer evening limb on tidally locked exoplanet WASP-94A b, implying strong day-night circulation and challenging past assumptions about uniform planetary atmospheres.
