Here is how I define 'galaxy':
NOUN
1) (a) (Astronomy) a huge cluster of stars consisting of the interstellar medium and dark matter that comes in various shapes as spiral, elliptical, and irregular and is the main component of the universe; (b) (Astronomy) (-G-) the huge star cluster containing the Sun and its planets and appearing as a luminous band stretching across Earth's night sky
2) a group of famous or successful people
Extragalactic
A spiral galaxy.
An Irregular Galaxy is a galaxy that has no shape or form as defined by the classes of the "Hubble sequence" An Amorphous galaxy is a galaxy that has neither spiral nor elliptical in shape as defined by "The Atlas of Peculiar Galaxies". See related links for pictorial representation
A galaxy is a single vast interstellar region held together by a huge gravitational field.
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.
Astronomers refer to a galaxy with a jumbled scattering of stars as an "irregular galaxy." These galaxies lack a defined shape or structure, distinguishing them from spiral or elliptical galaxies. Irregular galaxies often contain young stars, gas, and dust, and they can be the result of gravitational interactions or collisions with other galaxies.
An irregular galaxy is a galaxy with no definite shape like spirals, lenticulars, and ellipticals.
A galaxy doesn't have a clearly-defined edge, just as Earth's atmosphere doesn't have a clearly-defined edge. That is to say, Earth's atmosphere gradually gets thinner when you go further away from Earth; in a similar way, the star density will gradually get less when you go away from a galaxy.

Biome
The term conserve can be defined as protecting from loss. It can also be defined as using something sparingly or being careful with something. Conserving energy for later use is an example using the term.
The U.S. Supreme Court has defined the term "search" to occur when
