The Engraved Hourglass Nebula (also known as MyCn 18 [2]) is a young planetary nebula in the southern constellation Musca. It was discovered by Annie Jump Cannon and Margaret W. Mayall during their work on an extended Henry Draper Catalogue (the catalogue was built between 1918 and 1924). At the time, it was designated simply as a small faint ...

Located 2.4° east of Eta Muscae is the magnitude-12.9 Engraved Hourglass Nebula (MyCn 18), [61] which lies about 8000 light-years distant from Earth. [62] To Eta's west lies IC 4191, a compact bluish planetary nebula of magnitude 10.6, [63] thought to lie around 10,750 light-years away from Earth. [64]
It spins at a rate of 30 times per second, spewing energy beams and taking on a decidedly pulsating appearance.
