THE star-system best known to us is the Galactic system, which is bounded by the Milky Way. About two million such systems of stars can now be observed; they are known as extra-galactic nebul. A random collection of extra-galactic nebul seems at first to show a bewildering variety of ...
The name of this strange system is an indication of how uncertain astronomers are about its nature. Typically, dwarf galaxies that orbit theMilky Wayare named after the constellation in which they are found, in this caseUrsa Major, the Great Bear. Meanwhile, faintstar clustersare named after t...
From our perspective inside the Milky Way, the resulting disk of stars would be seen as a band of light arching across the sky. Kant even suggested that some of the nebulae visible in astronomer's telescopes are distant, separate star systems themselves, similar to the Milky Way and he ...
Milky Way n. 1.The galaxy containing the sun, solar system, and all of the individually visible stars in the night sky, along with various nebulae, star clusters, and dust clouds, thought to have a super-massive black hole at its center of mass. ...

Yet, the team still suspects something else might influence this, with Negueruela suggesting it could be related to how many stars in the cluster are part of binary or multiple-star systems or even the properties of these binaries. An artist's impression of exoplanets orbiting a red ...

but systems as thin as the Milky Way’s are still very rare12. Moreover, any planes that do form inΛCDM are transient, chance alignments of substructures14,20,21,22rather than long-lived, rotationally supported disks. We examine here the contention that the MW contains an exceptional plane...
