Are galaxies evenly distributed throughout the universe?

Galaxies and dark matter are not spread uniformly across the Universe, and instead have been concentrating, under the pull of gravity, into a weblike structure of clusters and filaments, with enormous voids in between.

Why are galaxies not uniformly distributed?

Galaxies are not evenly distributed throughout the universe. Gravity tends to make galaxies clump together. Galaxy clusters typically contain hundreds or even thousands of galaxies. …

Who found out that stars are not uniformly distributed in space?

Are stars uniformly throughout the universe?

Even to the unaided eye, it is obvious that the stars are not evenly distributed over the heavens. The eye is at once attracted by such brilliant regions as Orion and Cygnus; while in Virgo and Capricornus there is plainly a dearth of stars.

Which is the correct order of the organization of our galaxies?

The answer is a) you, Earth, solar system, Milky Way galaxy, local group, local supercluster, universe. The first four are familiar to us.

How are galaxies spread throughout the universe quizlet?

How are galaxies spread throughout the universe? Clusters of galaxies exist that are themselves often clustered into superclusters. Clusters and superclusters appear to be distributed on surfaces surrounding empty regions of space.

How are galaxies organized within the universe?

How are galaxies organized and distributed within the universe? Galaxies are typically organized into clusters and distributed (not scattered randomly) across the universe. In clusters, galaxies are held together by the force of gravity. If a cluster contains numerous galaxies, then it is a supercluster.

Can the Hubble telescope see other galaxies?

The telescope observes comets and planets. Hubble even discovered moons around Pluto that had not been seen before. The telescope has helped scientists understand how planets and galaxies form. A picture called “Hubble Ultra Deep Field” shows some of the farthest galaxies ever seen.

How are irregular and elliptical galaxies similar?

Elliptical galaxies don’t actively create new stars, but usually contain very old stars and little gas and dust. The stars in an elliptical galaxy are often close together, making the center seem like one giant star. Irregular galaxies are those with no defined shape.

What is cosmological red shift?

In cosmological redshift, the wavelength at which the radiation is originally emitted is lengthened as it travels through (expanding) space. Cosmological redshift results from the expansion of space itself and not from the motion of an individual body.

What characteristics is used to classify galaxies?

Edwin Hubble invented a classification of galaxies and grouped them into four classes: spirals, barred spirals, ellipticals and irregulars. He classified spiral and barred spiral galaxies further according to the size of their central bulge and the texture of their arms.
