What are Featureless galaxies containing old red main-sequence stars and red giants called?
If they have red stars including giants in, they can't be all that featureless.
What are galaxies found in clusters called?
They are simply called "galaxies which are part of a cluster".
What galaxies are sometimes called dwarf galaxies being typically smaller than spiral galaxies?
Elliptical galaxies are sometime called dwarf galaxies.
What are galaxies that are round and disk-like called?
They are called elliptical galaxies.
Why are they called weird galaxies?
irregular galaxies
A what is agroup of galaxies?
A group of galaxies is called a cluster.
What are football shaped galaxies called?
They are elliptical galaxies.
Is it true that elliptical galaxies are sometimes called dwarf galaxies?
You can have dwarf elliptical galaxies.
These galaxies have arms winding outward from inner regions?
They are called Spiral Galaxies or Barred Galaxies.
What is a vast collection of stars?
A vast collection of stars is called a galaxy. Galaxies are massive systems that contain stars, planets, gas, dust, and dark matter, held together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
What is called the dwarf galaxies?
Dwarf galaxies are small galaxies that contain relatively few stars compared to larger galaxies, typically having a total stellar mass of less than a billion solar masses. They can be classified into different types, such as dwarf elliptical, dwarf irregular, and dwarf spheroidal galaxies. Despite their small size, dwarf galaxies can play a significant role in our understanding of galaxy formation and evolution, as well as dark matter. They often exist in groups or clusters and can be satellites of larger galaxies, like the Milky Way.
Which sources of light have been found to be collections of billions of stars and not individual stars?
Galaxies, such as the Milky Way and Andromeda, are sources of light that have been found to be collections of billions of stars rather than individual stars. These galaxies contain vast numbers of stars, dust, and gas held together by gravity.
