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.

High-precision laboratory studies of meteorites as well as terrestrial and lunar rocks, which reveal tiny differences in isotopic composition, provide valuable insights into the formation and evolution of the early Solar System, enable dating important events, and help us understand how our Solar System with its planets, moons, and small bodies became what it is today. more
