Does the Milky Way correspond to the part of the sky where you saw more stars?

The answer is no – unless you count seeing the combined light of many billions of stars. From the Northern Hemisphere, the only galaxy outside our Milky Way that’s easily visible to the eye is the great galaxy in the constellation Andromeda, also known as M31.

What is mainly found in the space between stars in the Milky Way galaxy?

Bottom line: The interstellar medium is the stuff between the stars. Made up mostly of hydrogen and helium gas – plus trace amounts of ices, silicate grains, and all the other elements – it contains all the material needed to make stars and planets.

Do we see stars from other galaxies in the night sky?

We can’t see individual stars in other galaxies. (And the only galaxy beyond our own that’s visible to the naked eye from the Northern Hemisphere is Andromeda — and you would need very dark skies and a map to find it.)

How are stars and galaxies arranged in space?

The stars are arranged in a pinwheel pattern with four major arms, and we live in one of them, about two-thirds of the way outward from the center. Most of the stars in our galaxy are thought to host their own families of planets.

How long does it take for light to travel from one side of the Milky Way galaxy to the other?

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.

Do we know how many galaxies there are?

While NASA previously determined that there were around two trillion galaxies in the universe, new findings say the number is more likely hundreds of billions.

How are galaxies organized?

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. Gravity also forms galaxies into different shapes: spiral, elliptical, and irregular.
