The Boomerang Nebula is a protoplanetary nebula [2] located 5,000 light-years from Earth in the constellation Centaurus. It is also known as the Bow Tie Nebula and catalogued as LEDA 3074547. [ 3 ] The nebula's temperature is measured at 1 K (−272.15 °C ; −457.87 °F ) making it the coolest natural place currently known in the Universe .
Enormous Lyα nebula (ELAN) Around the quasar UM287 at around z=2.3. Cosmic filament illuminated by the quasar. MAMMOTH-1: 1,441,000 ly (442,000 pc) [7] Enormous Lyα nebula (ELAN) The nebula is associated with the galaxy overdensity BOSS1441, [7] which is a protocluster at z=2.3. The nebula represents the circumgalactic medium. Its emission is ...
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 .

The structure in the nebula is among the most complex ever seen in planetary nebulae. The spectrum of Butterfly Nebula shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius, implying that the star from which it formed must have been very large.
Researchers have unveiled intricate details of the star-forming region known as the Tarantula Nebula which lies 170,000 light years from Earth. Scientists map violent nebula to discover how stars ...
The name Tarantula Nebula arose in the mid-20th century from its appearance in deep photographic exposures. [7] 30 Doradus has often been treated as the designation of a star, [8] [9] or of the central star cluster NGC 2070, [10] but is now generally treated as referring to the whole nebula area of the Tarantula Nebula. [11] [12]
The Orion Nebula is part of a much larger nebula known as the Orion molecular cloud complex, which extends throughout the constellation of Orion and includes Barnard's Loop, the Horsehead Nebula, M43, M78, and the Flame Nebula. Stars are forming throughout the entire Cloud Complex, but most of the young stars are concentrated in dense clusters ...
