GN 04.32.8 (DG 41) is a reflection nebula located in the Taurus molecular cloud, a prominent region of star formation approximately 480 light-years from Earth in the constellation of Taurus. The nebula is illuminated by a cluster of young, hot stars, including the central T Tauri star system, and features a prominent protoplanetary disk associated with an embedded protostar, making it a valuable site for studying early stages of planetary formation.[3][4][5][6]

At its core lies a triple star system comprising the variable star HP Tauri and the gravitationally bound companions HP Tau G2, and HP Tau G3.[7][8]

Observation

GN 04.32.8 has been observed as part of broader surveys of the Taurus molecular cloud since the mid-20th century,[9] but gained prominence through high-resolution imaging by the NASA's Hubble Space Telescope. A detailed image captured by Hubble's Wide Field Camera 3 was released as the Hubble Picture of the Week on 30 June 2025, highlighting the nebula's intricate dust lanes and stellar content.[7]
