One last goodbye from the Menzel 2 nebula
The Hubble Space Telescope took a picture of the planetary nebula PK 329-02.2, also known as ESO 178-15 or Hen 2-150 and commonly called Menzel 2 (Mz 2) because it was discovered by the astronomer Donald Menzel in 1922. Distant little more 7,700 light years from Earth, it’s visible in the constellation Norma and is another case in which a planetary nebula offers a breathtaking show, in this case with a blue cloud that aligns with the two stars at its center.
