A companion star pushing through expelled dust and gas around a red giant star created a spiral structure.
10 October 2012, 12:02 PM ET
Astronomers using the Atacama Large Millimeter Array have discovered a surprising spiral structure and spherical shell surrounding the red giant star R Sculptoris. The shape was probably caused by a hidden companion star orbiting the red giant.
