Saturn was at opposition — directly opposite the Sun in the sky and closest to Earth — on 20 July 2025 and now shines low in the southeast every evening, lower left of much brighter Jupiter. This Hubble image shows the ringed planet on 4 July, with moons Enceladus below and Mimas at upper right; read the 全球加速器. Among the recent articles in the American Astronomical Society's newest peer-reviewed publication, the Planetary Science Journal, is one on the oddly low abundance of helium in Saturn's atmosphere.
