Globular clusters and very small galaxies.
They (scientists) think there are hundreds of thousands of galaxies because the universe is limitless so there may be billions of galaxies!
The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Galaxies contain stars and nebulae, as well as a large variety of other phenomena.
Yes. Our local group of galaxies is made up of 3 larger galaxies (milky-way, Andromeda and M33) and several smaller or dwarf galaxies.
The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".
A group of galaxies is called a galaxy cluster or galaxy group.
No. The local group contains the Milky Way and a few other galaxies.
None. Galaxies on the other hand do contain planets
We are part of the Local Group. The Local Group contains the Milky Way, two other major galaxies, and dozens of dwarf galaxies. The Local Groups is a group of galaxies which, as galaxies go, are close to us.
A group of galaxies is called a cluster.
