Is there anything in space between galaxies?

The space between stars is known as interstellar space, and so the space between galaxies is called intergalactic space. These are the vast empty spaces that sit between galaxies. Intergalactic space is as close as you can get to an absolute vacuum.

Are there any stars between 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.

What elements make up galaxies?

Many of those points of light are actually galaxies — collections of millions to trillions of stars. Galaxies are composed of stars, dust and dark matter, all held together by gravity. Astronomers aren’t certain exactly how galaxies formed. After the Big Bang, space was made up almost entirely of hydrogen and helium.

Are there planets between galaxies?

Yes. There are “rogue stars” and “rogue planets” between the galaxies. As Jess H. Brewer mentioned, stars and planets can be ejected from galaxies by odd gravitational interactions.

How cold are galaxies?

Jan. 30, 2014: Everyone knows that space is cold. In the vast gulf between stars and galaxies, the temperature of gaseous matter routinely drops to 3 degrees K, or 454 degrees below zero Fahrenheit. It’s about to get even colder.

What will happen if galaxies collide?

When you’re wondering what happens when two galaxies collide, try not to think of objects smashing into each other or violent crashes. Instead, as galaxies collide, new stars are formed as gasses combine, both galaxies lose their shape, and the two galaxies create a new supergalaxy that is elliptical.

How are galaxies created?

Galaxies are thought to begin as small clouds of stars and dust swirling through space. As other clouds get close, gravity sends these objects careening into one another and knits them into larger spinning packs.
