ALMA:n kuva HL Tauria ympäröivästä protoplanetaarisesta kiekosta
Tämä on tarkin ALMA:lla koskaan otettu kuva. Se on tarkempi kuin mitä NASA/ESA:n Hubble-avaruusteleskoopilla on yleensä saatu näkyvän valon alueella. Kuvassa näkyy nuoren HL Tauri -tähden ympärillä oleva protoplanetaarinen kiekko. Nämä uudet ALMA-havainnot paljastavat kiekon sisällä alirakenteita, joita ei ole koskaan aiemmin nähty. Niissä näkyy jopa järjestelmän tummilla alueilla mahdollisesti muodostuvien planeettojen sijaintipaikat.
