NGC 4565
spiral galaxy in the constellation Coma Berenices
NGC 4565 (also known as the Needle Galaxy, Flying Saucer Galaxy, Berenice's Hair Clip or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10.42. It is a prominent example of an edge-on spiral galaxy, known as the Needle Galaxy for its narrow profile. It was discovered by William Herschel on 6 April 1785.
Characteristics
NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy. Much speculation exists concerning the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot adjudge among various options. However, its exponential shape suggested that it is a barred spiral galaxy. Studies with the help of the Spitzer Space Telescope not only confirmed the presence of a central bar but also showed a pseudobulge within it, as well as an inner ring.
This edge-on galaxy exhibits a slightly warped and extended disk under deep optical surveys, likely due to ongoing interaction with neighboring satellite galaxies or other galaxies in the Coma I group.
“NGC 4565” enters the record as spiral galaxy in the constellation Coma Berenices. Crown Archives preserves that source wording while asking what spiral, galaxy and constellation can confirm, complicate or overturn.
Why this record matters
“NGC 4565” is worth following because a concise public description often conceals a longer documentary argument. Here, spiral, galaxy and constellation provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q622690. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1785.
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.
