NGC 1554
reflection nebula in the constellation Taurus
NGC 1554, Struve's Lost Nebula, is a list entry in the New General Catalogue of Nebulae compiled by John L. E. Dreyer. The nebula was discovered by the German-Russian astronomer Otto Wilhelm von Struve and confirmed by Heinrich Louis d'Arrest.
Dreyer describes it as
!!! var, S, R, Nn = *13
which in NGC's encoding is expanded to
a magnificent or otherwise interesting object, variable, small, round, nucleus north of a star of the 13th magnitude
The identification is uncertain; many sources think it is related to NGC 1555, Hind's Variable Nebula, but at NGC 1554's coordinates, (epoch J2000) 04h 22m 00.0s +19° 36′ 00″ there is no nebula. However, there is a 14th magnitude star, 4' west-southwest of T Tauri, so there is a possibility that the nebula Struve discovered was surrounding a variable star and it only flares up every now and then (perhaps even on a centuries long cycle). Alternatively it may have been an error caused by a pair of faint stars.
In fiction
In the 2014 video game Elite: Dangerous, Struve's Lost Nebula is featured as a small planetary nebula near the Pleiades cluster, and approximately 300 light years away from Earth. It has no star, so it physically can not be reached due to the mechanics of the game. This is likely due to an error in creating the astrometrics in the game, which is not uncommon for the game and has been a longstanding issue. There is also a Struve's Lost Sector within the game, but again, due to an error in the game's galactic map, the nebula itself is not within this sector.
“NGC 1554” enters the record as reflection nebula in the constellation Taurus. Crown Archives preserves that source wording while asking what reflection, nebula and constellation can confirm, complicate or overturn.
Why this record matters
“NGC 1554” is worth following because a concise public description often conceals a longer documentary argument. Here, reflection, nebula and constellation provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 9, 2025. The linked authority identifier is Q1044002. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1554, 1555 and 2014.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
