A planetary nebula is the corpse that remains when a star dies. When planetary nebulae were observed for the first time with a telescope, they presented a roughly circular shape, resembling that of the gas giant planets. Hence their name, which remains in use even though they are very different from planets. The article published recently by Astronomy & Astrophysics is the first detailed study of a galactic planetary nebula with the MUSE integral field spectrograph on ESO's Very Large Telescope ...
