Elliptical, Irregular, and Spiral
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
Yes. Some spiral galaxies do contain at least 1 trillion stars.
Some galaxies are spiral, similar to the Milky Way.
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Approximately 60% of all galaxies are spiral
spiral, barred spiral, elliptical, irregular, and peculiar
some are big.
Yes. Some spiral galaxies are up to 13 billion light-years from Earth.
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
