This fan-shaped nebula opens from the star R Coronae Australis toward the star T CrA to the south-east. R CrA is a pre-main-sequence star in the Corona Australis molecular complex, one of the closer star-forming regions of the galaxy at a distance of 130 pc. [1] NGC 6729 is a variable nebula which shows irregular variations in brightness and in ...
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius.The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars.
Credit: T.A. Rector (University of Alaska Anchorage) and H. Schweiker (WIYN and NOIRLab/NSF/AURA) Sharpless 101 (Sh 2-101) is a H II region [1] emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically.
NGC 6210, sometimes also known as the Turtle Nebula, [4] is a planetary nebula located in the constellation Hercules, approximately 5.4 ± 1.3 kly from the Sun. [2] It is positioned about 38° above the galactic plane at a vertical distance of about 3.3 kilolight-years (1 kpc) and thus has little extinction from intervening interstellar dust. [5]
NGC 1514, also known as the Crystal Ball Nebula, [3] is a planetary nebula in the zodiac constellation of Taurus, [2] positioned to the north of the star Psi Tauri along the constellation border with Perseus. [4] Distance to the nebula is 466 pc, according to GAIA DR2 data. [full citation needed]
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 .
Orion Nebula: 20 ly (6.132 pc) [64] Diffuse Nebula: The closest major star formation region to Earth. [65] Crab Nebula: 11 ly (3.4 pc) [66] Supernova remnant: The remnant of a supernova that occurred in 1054 AD. [67] Bubble Nebula: 6 [68]-10 [69] [70] ly (1.84-3.066 pc) Emission nebula: Helix Nebula: 5.74 ly (1.76 pc) [71] Emission nebula ...
