Is the Milky Way infinite?
Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations. Public Domain Image, source: NASA/JPL-Caltech/ESO/Univ.
How do we know that space is infinite?
To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite. If it’s curved, like Earth’s surface, then it has finite volume.
Is the Milky Way small medium or large?
The Milky Way is only a medium sized galaxy with an estimated 200 billion stars. The largest galaxy we know of is called IC 1101 and has over 100 trillion stars.
How does the Milky Way compare in size to other galaxies?
The Milky Way is an averagely large galaxy with a diameter of 100 000 light years and about 200 billion to 400 billion stars; but compared to larger galaxies like M100, M 87, NGC 4921 or Hercules A, the Milky Way looks like a dwarf galaxy.

What is the size of Universe?
93 billion light-years
The observable Universe is 93 billion light-years in diameter. Some scientists believe its true size is even scarier than that. By using the Bayesian model averaging, scientists estimated that the Universe is at least 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.
Is the Milky Way a finite Galaxy?
Answer Wiki. Our galaxy the Milky Way and all other galaxies are most definitely finite. Ours is a spiral shaped disk somewhere between 100-150,000 light years across and a thousand or so light years thick. There are at least 100 billion and perhaps as many as 400 billion stars in the Milky Way.
What does the Milky Way look like?
The Milky Way is a huge city of stars, so big that even at the speed of light, it would take 100,000 years to travel across it. All the stars in the night sky, including our Sun, are just some of the residents of this galaxy, along with millions of other stars too faint to be seen. The further away a star is, the fainter it looks.
Is the Milky Way spiral or elliptical?
The concentration of stars in a band adds to the evidence that the Milky Way is a spiral galaxy. If we lived in an elliptical galaxy, we would see the stars of our galaxy spread out all around the sky, not in a single band. An all-sky image shows the flat plane of the Milky Way galaxy.
How long would it take to travel across the Milky Way galaxy?
It would take the Space Shuttle seven months to fly there. When we leave the solar system, we find our star and its planets are just one small part of the Milky Way galaxy. The Milky Way is a huge city of stars, so big that even at the speed of light, it would take 100,000 years to travel across it.
