The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
As with other voids, it is not completely empty; it contains the Milky Way, the Local Group, and the larger part of the Laniakea Supercluster. The Milky Way is within a few hundred million light-years of the void's center. [5] It is debated whether the existence of the KBC void is consistent with the ΛCDM model.
The Milky Way has several smaller galaxies gravitationally bound to it, as part of the Milky Way subgroup, which is part of the local galaxy cluster, the Local Group. [ 1 ] There are 61 small galaxies confirmed to be within 420 kiloparsecs (1.4 million light-years ) of the Milky Way, [ 2 ] but not all of them are necessarily in orbit, and some ...
Overview sketch of the Milky Way with the direction of the Galactic anticentre indicated, as seen from the Solar System [1] Map of the Auriga constellation. Elnath is the star at the bottom of the ring. The galactic anticenter is a direction in space directly opposite to the Galactic Center, as viewed from Earth.
The Local Sheet in astronomy is a nearby extragalactic region of space where the Milky Way, the members of the Local Group and other galaxies share a similar peculiar velocity. [2] This region lies within a radius of about 7 Mpc (23 Mly), [3] 0.46 Mpc (1.5 Mly) thick, [1] and galaxies beyond that distance show markedly different velocities. [3]
Based upon the emerging science of nucleocosmochronology, the Galactic thin disk of the Milky Way is estimated to have been formed 8.8 ± 1.7 billion years ago. [6] It may have collided with a smaller satellite galaxy, causing the stars in the thin disk to be shaken up and creating the thick disk, [ 7 ] while the gas would have settled into the ...
Stellar streams in the Milky Way, discovered in 2007. This is a list of stellar streams.A stellar stream is an association of stars orbiting a galaxy.It was once a globular cluster or dwarf galaxy that has now been torn apart and stretched out along its orbit by tidal forces. [1]
The Via Lattea (italian for Milky Way) is a winter sports area in the Italian and French Alps, straddling the French-Italian border at Claviere/Montgenèvre. Located some 70 km (44 miles) west of Turin , it comprises the five Piedmontese resorts of Claviere (1760m), Sansicario (1700m), Sauze d'Oulx (1509m), Pragelato (1524m) [ 2 ] and Sestriere ...
