Protoplanetary disc around HL Tauri

摘要[編輯]

描述
English: ALMA image of the protoplanetary disc around HL Tauri - This is the sharpest image ever taken by ALMA — sharper than is routinely achieved in visible light with the NASA/ESA Hubble Space Telescope. It shows the protoplanetary disc surrounding the young star HL Tauri. These new ALMA observations reveal substructures within the disc that have never been seen before and even show the possible positions of planets forming in the dark patches within the system.
