The clouds are an obstruction to millions of the galaxy's stars detected at visible wavelengths, which compose a bright hazy band appearing 30° wide and arching through the night sky. The clouds within our radial sector of the galaxy span about 800–1,000 parsecs (2,600–3,300 ly ) from Earth. [ 1 ]
Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within the Milky Way galaxy at a distance of about 125 parsecs (407 light-years). [2] It is both close and dense enough that stars behind it cannot be seen from Earth.
The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy , the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [ 1 ] [ 3 ] and contains several hundred million stars. [ 5 ]
In the background are the southern Milky Way on the left and the Magellanic Clouds at the top. [1] The Magellanic Clouds (Magellanic system [2] [3] or Nubeculae Magellani [4]) are two irregular dwarf galaxies in the southern celestial hemisphere. Orbiting the Milky Way galaxy, these satellite galaxies are members of the Local Group.
The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way. The general direction of the Sun's Galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The Sun's orbit about the Milky Way is ...
NGC 290 is an open cluster of stars in the southern constellation of Tucana.This cluster was discovered September 5, 1826, by Scottish astronomer James Dunlop. [7] It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy.
Portal:Astronomy/Picture/7 August 2005. Cigar galaxy, complements of NASA. The Cigar Galaxy is an irregular galaxy 12 million light years away. It can also be called M82 or NGC 3034. The galaxy is a starburst galaxy in the Ursa Minor constellation. This image was obtained as part of the Two Micron All Sky Survey. 9 August 2005 . 10 August 2005
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [ 1 ] [ 2 ] Its central massive object is a supermassive black hole of about 4 million solar masses , which is called Sagittarius A* , [ 3 ] [ 4 ] [ 5 ] a compact radio source which is almost exactly at the galactic rotational ...
