Richtige Antwort: AA gravitationally bound system of stars, gas, dust, and dark matter
Galaxies are enormous gravitationally bound systems containing stars and interstellar material, with dark matter contributing much of their total mass.
Richtige Antwort: CBarred spiral galaxy
Observations indicate that the Milky Way has spiral arms extending from a central bar-shaped concentration of stars.
Richtige Antwort: BA collection of galaxies that includes the Milky Way and Andromeda
The Local Group is a gravitationally associated collection of galaxies whose largest members include the Milky Way, Andromeda, and the Triangulum Galaxy.
Richtige Antwort: DGalaxies form a web of filaments, clusters, and large voids
On very large scales, matter forms the cosmic web, with dense filaments and nodes separated by enormous regions containing relatively little matter.
Richtige Antwort: ALarge gravitationally bound collections containing hundreds or thousands of galaxies
Galaxy clusters are among the largest gravitationally bound structures and contain galaxies, hot gas, and substantial amounts of dark matter.
Richtige Antwort: BA large region of space containing relatively few galaxies
Cosmic voids are enormous underdense regions between the filaments and clusters that make up the cosmic web.
Richtige Antwort: CThe region from which information has had enough time to reach us
Because light travels at a finite speed and the universe has a finite age, there is a limit to the regions from which signals could have reached us.
Richtige Antwort: DContribute additional gravity that influences the motion of visible matter
Dark matter does not emit detectable light, but its gravitational effects help explain observed motions of stars and galaxies that visible matter alone cannot account for.
Richtige Antwort: AA supermassive black hole
Observations of stellar and gas motions indicate that most large galaxies contain black holes with masses millions or billions of times that of the Sun.
Richtige Antwort: BLarge elongated structures containing galaxies and matter
Cosmic filaments are vast concentrations of matter that connect denser regions such as galaxy groups and clusters.
Richtige Antwort: COn large scales, distances between gravitationally unbound galaxies increase over time
Cosmic expansion refers to the increase of large-scale distances as space expands, rather than ordinary motion caused by objects traveling through static space.
Richtige Antwort: DStar system, galaxy, galaxy cluster, cosmic web
Star systems are components of galaxies, galaxies can belong to clusters, and clusters and galaxies collectively trace the much larger cosmic web.
