Milky Way Galaxy (sometimes simply called the Galaxy), large spiral system of about several hundred billion stars, one of which is the Sun. It takes its name from the Milky Way, the irregular luminous band of stars and gas clouds that stretches across th
We can then confirm that we are effectively in a weak gravitational field at the end of the galaxy. Another way is to verify that one has \(\vert h_{\mu \nu }\vert <<1 \) from the traditional decomposition of the GR metric \(g_{\mu \nu }=\eta _{\mu \nu }+h_{\mu \nu...
Edward Emerson Barnard was an astronomer who pioneered in celestial photography and who was the leading observational astronomer of his time. In 1889 he began to photograph the Milky Way with large-aperture lenses, revealing much new detail. He discovere

Great Rift, in astronomy, a complex of dark nebulae that seems to divide the bright clouds of the Milky Way Galaxy lengthwise through about one-third of their extent. From the constellation Cygnus, the rift reaches through Aquila and Sagittarius, where t
