Based on the red-shift data on galaxies, most astronomers infer that the universe is currently
Lightyears (LY)
blue shifted lines.
expanding
the distance traveled by light in one year
shift toward the red end of the spectrum
They may contain billions of stars in a space much larger than our solar system.
a spiral-shaped formation composed of billions of stars
further away from us
The unit most used by astronomers to express the distances to other galaxies is
Lightyears (LY)
blue shifted lines.
expanding
the distance traveled by light in one year
shift toward the red end of the spectrum
They may contain billions of stars in a space much larger than our solar system.
a spiral-shaped formation composed of billions of stars
further away from us
The Milky Way galaxy is best described as
Lightyears (LY)
blue shifted lines.
expanding
the distance traveled by light in one year
shift toward the red end of the spectrum
They may contain billions of stars in a space much larger than our solar system.
a spiral-shaped formation composed of billions of stars
further away from us
According to Hubbell's law more rapidly moving galaxies are now
Lightyears (LY)
blue shifted lines.
expanding
the distance traveled by light in one year
shift toward the red end of the spectrum
They may contain billions of stars in a space much larger than our solar system.
a spiral-shaped formation composed of billions of stars

Which statement best describes galaxies?
Lightyears (LY)
blue shifted lines.
expanding
the distance traveled by light in one year
shift toward the red end of the spectrum
They may contain billions of stars in a space much larger than our solar system.
a spiral-shaped formation composed of billions of stars
further away from us
According to the big bang theory, the universe began as an explosion and is still expanding. This theory is supported by observations that the stellar spectra of distant galaxies show a
Lightyears (LY)
blue shifted lines.
