Historically, astronomical observatories consisted generally in a building or group of buildings where observations of astronomical objects such as sunspots, planets, asteroids, comets, stars, nebulae, and galaxies in the visible wavelengths of the electromagnetic spectrum were conducted. At first, for millennia, astronomical observations have ...
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
Its population of approximately 150 stars of 7th magnitude or fainter includes seven red giants [15] and seven white dwarfs. [16] [17] On 20 May 1990 it became the first target ever observed by the Hubble Space Telescope. A line from Beta Crucis through Delta Crucis passes somewhat to the north of NGC 3532.

Prominent stars in the neighborhood of the Sun (center) This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.
In 1957, German astronomer Wilhelm Gliese published his first star catalogue of 915 known stars within 20 parsecs (65 ly) of Earth, listing their known properties and ordered geographically by right ascension. [1] Stars in the first catalogue are designated by coding GL NNN, the N representing the consecutive integer number based on this order. [2]
Messier 38 or M38, also known as NGC 1912 or Starfish Cluster, [4] is an open cluster of stars in the constellation of Auriga. It was discovered by Giovanni Batista Hodierna before 1654 and independently found by Le Gentil in 1749. The open clusters M36 and M37, also discovered by Hodierna, are often grouped together with M38. [5]
The strong geomagnetic storm that created such a show has subsided, according the National Oceanic and Atmospheric Administration, but some parts of the U.S. may again see the northern lights ...
