Summary edit

"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."

Description	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.

Rationale	No free licensed or public domain alternatives known to exist to show 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.

Image title	Chandra's image shows Mira A (right), a highly evolved red giant star, and Mira B (left), a white dwarf. To the right of the image is an artist's conception of this interacting star system. 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. An unexpected X-ray outburst from Mira A was observed by Chandra. This outburst was likely an indirect consequence of the internal turmoil in Mira A, which is now approaching the stage where its nuclear fuel supply will be exhausted. It will eventually collapse to become a white dwarf, like Mira B.
