Tarantula Nebula
H II region in the constellation Dorado
The Tarantula Nebula (also known as 30 Doradus) is a large H II region in the Large Magellanic Cloud (LMC), forming its south-east corner (from Earth's perspective). The nebula is named for the arrangement of its bright, glowing gas filaments and dusty tendrils which stretch outward and look like the legs of a tarantula.
Discovery
The Tarantula Nebula was observed by Nicolas-Louis de Lacaille during an expedition to the Cape of Good Hope between 1751 and 1753. He cataloged it as the second of the "Nebulae of the First Class", "Nebulosities not accompanied by any star visible in the telescope of two feet". It was described as a diffuse nebula 20' across.
Johann Bode included the Tarantula in his 1801 Uranographia star atlas and listed it in the accompanying Allgemeine Beschreibung und Nachweisung der Gestirne catalog as number 30 in the constellation "Xiphias or Dorado". Instead of being given a stellar magnitude, it was noted to be nebulous.
The name Tarantula Nebula arose in the mid-20th century from its appearance in deep photographic exposures.
30 Doradus has often been treated as the designation of a star, or of the central star cluster NGC 2070, but is now generally treated as referring to the whole nebula area of the Tarantula Nebula.
Properties
The Tarantula Nebula has an apparent magnitude of 8.
Begin with the source’s own compact description: “Tarantula Nebula” is h II region in the constellation Dorado. The dossier treats that line as a proposition to test through Tarantula, Nebula and region, not as a finished interpretation.
Why this record matters
The phrase “h II region in the constellation Dorado” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q224145. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1751, 1753, 1801 and 2070.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
