The Atacama Large Millimeter/submillimeter Array (ALMA) has discovered that two young stars forming from the same swirling protoplanetary disc could in fact be twins
This unusual collection of massive planets makes astronomers question how planets are formed
By simulating the movement of dust as it moves through gas shows how larger clumps of material form, eventually leading to the formation of planets
New clues to understanding how dust can find its way to the surface of a forming star have been uncovered
Astronomers have taken a new, detailed look at the very early stages of planet formation embedded in a binary star’s protoplanetary disc
