The Hourglass Nebula (MyCn18) is a young planetary nebula located about 8,000 light years away in Musca Constellation.
The central star of the Hourglass Nebula is a hot Wolf-Rayet (WR) star, with a temperature of about 110,000 K. The star has ejected its material and is now responsible for the nebula’s glow.
MyCn18 is approaching us at an approximate velocity of 67.8 kilometers per second.
The Hourglass Nebula expands at 10 kilometers per second.
