  3. Binary Star System
    Most stars in the universe come in pairs. In a binary system, two stars orbit a common center of mass. Some, like V664 Cas, evolve into spectacular sights. This red giant and white dwarf orbit every 0.58 days, creating the planetary nebula HFG1 and a glowing arc-shaped shockwave.
