Box Nebula NGC 6445: 1786 4.5 11.2 Sagittarius: Eye of Sauron Nebula M 1-42: 10 14 Sagittarius
NGC 2818 is a planetary nebula located in the southern constellation Pyxis (The Compass). It consists largely of glowing gases from the star's outer layers ejected during the final stages of its life when it had run out of the fuel necessary to sustain its core fusion processes.
The entirety of the Orion Nebula extends across a 1° region of the sky, and includes neutral clouds of gas and dust, associations of stars, ionized volumes of gas, and reflection nebulae. The Nebula is part of a much larger nebula that is known as the Orion molecular cloud complex .
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
NGC 6326, a planetary nebula with glowing wisps of outpouring gas that are lit up by a binary [3] central star. A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. [4] The term "planetary nebula" is a misnomer because they are unrelated to ...
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 .
Based on the expansion rate, the estimated age of the nebula is 3,080 years. [5] The central star of the planetary nebula is a subdwarf O star with a spectral type of sdO. [7] The best fit model for this star gives an effective temperature of 100 kK, with 5,250 times the luminosity of the Sun [5] and 60.5% of the Sun's mass. [6]
NGC 6188, also known as the Firebird Nebula, is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188.
