NGC 4361's central star, which has the Henry Draper Catalogue designation HD 107969, [5] is an extremely hot [WC] Wolf-Rayet type star.Its temperature is 126,000 K. [6] It is nearly 18,000 times brighter than the Sun, but is only 6.1% its size.
The Ring Nebula is located in the lower right of the image Gum Nebula: 809–950 ly (248–291 pc) [16] [17] Emission nebula: Extends about 36° of the sky Bubble Nebula (NGC 6822) 758 ly (232 pc) [18] [19] [20] H II region: The Bubble Nebula is located in the upper left of the image NGC 6188: 600 ly (180 pc) [21] Emission nebula: NGC 592
It is associated with a dark cloud L1450 (Barnard 205). Estimates of the distance to this nebula range from 980–1,140 ly (300–350 pc). [4] This nebula is in the western part [4] of the Perseus molecular cloud and is a young region of very active star formation, [6] being one of the best-studied objects of its type. [4]
Gyulbudaghian's Nebula (gyool-boo-DAH-ghee-an) is a reflection nebula in the northern constellation Cepheus, located about 1.5 degrees west of the much brighter reflection nebula NGC 7023. The light illuminating it comes from the T Tauri star PV Cephei .
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
It is known as the Blue Snowball Nebula, Snowball Nebula, and Caldwell 22. This nebula was discovered October 6, 1784 by the German-born English astronomer William Herschel . In the New General Catalogue it is described as a "magnificent planetary or annular nebula, very bright, pretty small in angular size , round, blue, variable nucleus".
Mz 3 is radially expanding at a rate of about 50 km/s and has its polar axis oriented at an angle of around 30° from the plane of the sky (Lopez & Meaburn 1983; Meaburn & Walsh 1985). It is sometimes compared to the more extensively studied Butterfly Nebula (M 2-9), and it is quite likely that both have a similar evolutionary history.
