Summary
"The Chandra image shows Mira A (right), a highly evolved red giant star, and Mira B (left), a white dwarf. Mira A is losing gas rapidly from its upper atmosphere via a stellar wind. Mira B exerts a gravitational tug that creates a gaseous bridge between the two stars. Gas from the wind and bridge accumulates in an accretion disk around Mira B and collisions between rapidly moving particles in the disk produce X-rays."

Scalebar: 0.3 arcsec.
