Explanation:
Sometimes stars work together to
create a spectacular display. Such is the case with the
binary star system
R Aquarii -
a "symbiotic" star system. Here two stars, a variable
giant and a
white dwarf companion -
create both a
nebula and a
jet. Light from the giant star and the
unusually shaped nebula are visible in the above photograph. The two
visible shells in the nebula likely resulted from two separate
outburst events. Much about symbiotic star systems remains unknown.
