The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north. It uses the right-handed convention ...
Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [ 7][ 8][ 9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
These are globular clusters within the halo of the Milky Way galaxy. The diameter is in minutes of arc as seen from Earth. For reference, the J2000 epoch celestial coordinates of the Galactic Center are right ascension 17h 45m 40.04s, declination −29° 00′ 28.1″. A high proportion of globular clusters are located in the Ophiuchus and ...
The "Teapot" asterism is in Sagittarius. The Milky Way is the "steam" coming from the spout. The galactic center Sagittarius A* is located off the top of the spout. As seen from the northern hemisphere, the constellation's brighter stars form an easily recognizable asterism known as "the Teapot".
The Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. [7] At a distance of around 50 kiloparsecs (163,000 light-years), [2] [8] [9] [10] the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.
The best dates to see the Milky Way are June 28 to July 8, July 28 to Aug. 7, Aug. 26 to Sep. 6 and Sep. 24 to Oct. 5. ... For the latest news, weather, sports, and streaming video, head to The ...
The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [ 3][ 4] Discovered by Brent Tully and Rick Fisher in 1987, [ 5] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments ". [ 4] The precise extent of the void is unknown, but it is at least 45 Mpc (150 ...
