3D view of LL Pegasi
This video shows the observed structure surrounding the binary star system LL Pegasi, as seen by the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA’s observations were able to reveal the exquisitely-ordered 3D geometry of the spiral pattern (seen to the left). The observations match almost perfectly with the predicted theoretical model (to the right).
