A video showing in 3D Laniakea and other nearby superclusters of galaxies The Laniakea Supercluster encompasses approximately 100,000 galaxies stretched out over 160 Mpc (520 million ly ). It has the approximate mass of 10 17 solar masses, or 100,000 times that of our galaxy, which is almost the same as that of the Horologium Supercluster . [ 3 ]
The Milky Way Project is a Zooniverse project whose main goal is to identify stellar-wind bubbles in the Milky Way Galaxy. Users classify sets of infrared images from the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer (WISE). [1] Scientists believe bubbles in these images are the result of young, massive stars whose light ...
MilkyWay@home is a volunteer computing project in the astrophysics category, running on the Berkeley Open Infrastructure for Network Computing (BOINC) platform. Using spare computing power from over 38,000 computers run by over 27,000 active volunteers as of November 2011, [3] the MilkyWay@home project aims to generate accurate three-dimensional dynamic models of stellar streams in the ...
The first project to describe the shape of the Milky Way and the position of the Sun was undertaken by William Herschel in 1785 by counting the number of stars in different regions of the sky. He produced a diagram of the shape of the galaxy with the Solar System close to the center .
The Local Group is the galaxy group that includes the Milky Way, where Earth is located. It has a total diameter of roughly 3 megaparsecs (10 million light-years; 9 × 10 19 kilometres), [1] and a total mass of the order of 2 × 10 12 solar masses (4 × 10 42 kg). [2] It consists of two collections of galaxies in a "dumbbell" shape; the Milky ...
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.
An artistic illustration of what it would look like from Earth during the Milky way-Andromeda galaxy collision event. The Andromeda Galaxy is approximately 2.5 million light years away from our galaxy, the Milky Way galaxy, and they are moving towards each other at approximately 300 kilometers (186 miles) per second.
Radcliffe wave. The approximate outline of the Radcliffe wave in Earth's night sky. The Radcliffe wave is a neighbouring coherent gaseous structure in the Milky Way, dotted with a related high concentration of interconnected stellar nurseries. It stretches about 8,800 light years. [ 1 ][ 2 ] This structure runs with the trajectory of the Milky ...
