Can we see past the Milky Way?

Answer: Yes, you can see a few other galaxies without using a telescope! The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.

What is past the Milky Way?

Cosmic Neighborhood The Milky Way galaxy is in the Local Group, a neighborhood of about 30 galaxies. Our nearest major neighboring galaxy is called Andromeda.

Are there stars outside of galaxies?

Although stars cannot form in the voids between galaxies (since the density of matter is far too low), there are in fact large numbers of ‘intergalactic stars’. It has been estimated, for example, that 10 per cent of the mass of the Virgo galaxy cluster is in the form of these stellar interlopers.

Do stars only exist within galaxies?

Answer: No, not all stars are in a galaxy. They may have once belonged to a galaxy, but they are not a part of it any more. Some of these so-called “stellar outcasts” or “intergalactic stars” have actually been observed by NASA’s Hubble Space Telescope.

How are superclusters distributed throughout the universe?

Galaxies are not distributed randomly throughout the universe, but are grouped in graviationally bound clusters. Recent observations show that superclusters are arranged in sheets with huge voids in between, and that matter in the universe is arranged in a filamentary structure.

How are superclusters 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.

What does the universe look like beyond the cosmological horizon?

We cannot look beyond the cosmological horizon because we cannot look back to a time before the universe began. 2. What does the universe look like on very large scales? a. Galaxies appear to be distributed in chains and sheets that surround great voids. b. Galaxies are uniformly distributed.

Why can’t we see stars further away from US?

We are unable to see the stars that are located at large distances from us across the Milky Way Galaxy suggesting unknown “Dark Matter” is absorbing their light. -the Big Bang explosion caused the constant expansion of space.

What happens when galaxies collide with each other?

Collisions between galaxies have little effect on individual stars. True When galaxies collide, the large-scale galactic structure is affected, but the individual stars are not. True Our theories of galaxy formation are just as well developed and tested as are our theories of star and planet formation.

What is true and false about the distance between galaxies?

Distant galaxies appear to be much larger than those nearby. False Collisions between galaxies are rare and have little or no effect on the stars and interstellar gas in the galaxies involved. False The quasar stage of a galaxy ends because the central black hole swallows up all the matter around it.
