WebObservations with ALMA. ALMA has obtained its most detailed image yet showing the structure of the disk around HL Tauri , a million-year-old Sun-like star located approximately 450 light-years from Earth in the constellation of Taurus.The image exceeds all expectations and reveals a series of concentric and bright rings, separated by gaps. HL Tauri (abbreviated HL Tau) is a very young T Tauri star in the constellation Taurus, approximately 450 light-years (140 pc) from Earth in the Taurus Molecular Cloud. The luminosity and effective temperature of HL Tauri imply that its age is less than 100,000 years. At apparent magnitude 15.1, it is too faint to be seen with the unaided eye. It is surrounded by a protoplanetary disk marke…
