Two white dwarfs shed outer layers of mass to form winding blue clouds of hot gas
Space news (October 16, 2015) – light-years away in the southern constellation Norma –
First discovered during modern times by noted astronomer Donald Menzel in 1922, planetary nebula PK 329-02.2 or Menzel 2 (Mz 2), is composed of a central star and companion sun cocooned in stunning, hot clouds of glowing gas ejected in complex shapes that will fade into the cosmos over the next few thousands of years.
Astrophysicists believe the star at the upper right of the two central stars shining brightly in this Hubble image is the main star of planetary nebula PK 329-02.2. The star just to the lower left of this central star astronomers believe is the companion sun, which is gravitationally tied to the main star.
Over tens of thousands of years, this pair of stars is expected to be cocooned in stunning clouds of hot, glowing gas. Swirling clouds forming a goodbye wave as the main star enters the final stages of its life cycle and starts to enjoy retirement as a white dwarf star.
