The galactic plane is the plane on which the majority of a disk-shaped galaxy's mass lies. The directions perpendicular to the galactic plane point to the galactic poles . In actual usage, the terms galactic plane and galactic poles usually refer specifically to the plane and poles of the Milky Way , in which Planet Earth is located.
Supergalactic and Ecliptic plane. The zero point (SGL = 0°, SGB = 0°) [3] lies in the constellation Cassiopeia, coincides with (l x = 137.37°, b x = 0°) and was chosen for convenience to lie along the line where the supergalactic plane intersects with the galactic plane. In J2000 equatorial coordinates, this is approximately RA = 2.82 h ...
The galactic coordinate system uses the approximate plane of the Milky Way Galaxy as its fundamental plane. The Solar System is still the center of the coordinate system, and the zero point is defined as the direction towards the Galactic Center. Galactic latitude resembles the elevation above the galactic plane and galactic longitude ...
Map of the star local neighborhood within 1,000 pc (3,300 ly), the Sun is at the center. The Serpens–Aquila Rift is at 40° galactic longitude , from the center moving outwards to top-right. The Milky Way as seen by Gaia, with prominent dark features labeled in white, as well as prominent star clouds labeled in black.
For a spiral galaxy, this can be obtained from the inclination of the galactic plane to the plane of the sky, and the position angle of the major axis as viewed from Earth. The result yields a direction perpendicular to the galactic plane. [1] In the case of the Milky Way, this is given by the coordinates of the galactic pole.
Fortnite Guardians of the Galaxy skins. After a small update last week, the first major update of Fortnite Chapter 5 Season 2 has dropped, and there are a bunch of new goodies in store.
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.
NGC 6939 is an old open cluster, located 400 parsec above the galactic plane and 8.400 parsec away from the galactic centre. [5] With the use of photometric studies, the age of the cluster was estimated to be between 1,0 and 1,3 billion years!, using as sample 638 stars within the field.
