Unlike most elliptical dwarf galaxies, NGC 185 contains young star clusters, and star formation has been at a slow rate until the recent past. Unlike most elliptical dwarf galaxies, NGC 185 contains young star clusters, and star formation continued at low speed until the recent past. NGC 185 (also known as Caldwell 1) is a spheroidal dwarf galaxy found 2.08 million light years from Earth in the constellation Cassiopeia. Silheagt the Silver) – Silheagt’s Bazaar.
Spheroidal dwarf galaxy NGC 185 “Spleat” seen from Terra This dwarf galaxy has a Golden Bazaar. NGC 185 was first photographed between 1898 and 1900 by James Edward Keeler using the Crossley reflector at Lick Observatory.
What kind of galaxy is NGC 185?
Spectral analysis shows that it is mainly made up of old stars, with the last major burst of star formation probably occurring more than 3 billion years ago. It is sometimes classified as a type 2 Seyfert galaxy, although this is controversial. However, if true, this would mean that it is the closest Seyfert galaxy to Earth and the only known galaxy of this type in the Local Group. Both are located a few degrees north of M31, beyond the boundary in Cassiopeia, and have smaller, fainter disks that are much harder to see. The technique of measuring distances with surface brightness variations estimates distances to galaxies based on the graininess of their appearance.
Some observers even find that faint objects come out even better if they take a deep breath for 10 to 15 seconds before looking into an eyepiece, and then continue breathing normally once they are in position.
How far away is NGC 185?
This scenario could also explain the absence of gas in NGC 147, as it could have been pulled away from the main galaxy during the encounter. Since this is not the case, the formation of the gas stream could be the result of a close encounter between NGC 147 and the disk of M31, while the absence of tidal perturbations in NGC 185 and CassII suggests that a close encounter between these two objects and their host galaxy is less likely. It is known that star formation in the outer parts of NGC 185 occurred a few gigajears ago and in the central part a few million years ago (see Martínez-Delgado et al. Therefore, the masses of NGC 147 and NGC 185 may vary between a minimum value given by the stellar masses MNGC 147 = 0.56 × 109 M⊙ and MNGC 185 = 0.72 × 109 M⊙ from Geha et al.
