The following well-known nebulae are listed for the purpose of comparison. Orion Nebula: 20 ly (6.132 pc) [48] Diffuse Nebula: The closest major star formation region to Earth. [49] Crab Nebula: 11 ly (3.4 pc) [50] Supernova remnant: The remnant of a supernova that occurred in 1054 AD. [51] Bubble Nebula: 6 [52]-10 [53] [54] ly (1.84-3.066 pc ...
The nebula contains ions of extremely high ionization potential. [20] The helium hydride ion, thought to be the earliest molecule to have been formed in the Universe (about 100,000 years after the Big Bang), was detected in 2019 for the first time in space in NGC 7027. [21] [22] There is also evidence for the presence of nanodiamond in NGC 7027 ...
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [3] The distance, measured by the Gaia mission, is 655±13 light-years. [4]

The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 5700 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years or about 90 trillion kilometers long. [6]
Researchers unearthed the skull of a previously unknown starling-sized bird species named Navaornis hestiae that was so well preserved they were able to digitally reconstruct its brain and inner ...
The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula approximately 2,030 light years away in the constellation Ursa Major. [2] Estimated to be about 8,000 years old, [ 6 ] it is approximately circular in cross-section with a faint internal structure.
The stars have long held a special resonance within Maori culture. Now, the plight of a small seabird has triggered a New Zealand community to seek dark sky status – and the results are awe ...
