A galaxy is a single vast interstellar region held together by a huge gravitational field.
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
energy is scientifically defined as the ability to do work.
They are albino Black Bears (They lack pigmentation)
WORK as is scientifically defined.
Extragalactic
A star is a spheroidal plasma converting mass into energy by nuclear fusion.
that has not scientifically proven yet and only time can tell us. but i highly doubt it
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.
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.
Life is scientifically defined as a characteristic that sets living organisms apart from non-living matter. It encompasses several key properties, such as metabolism, growth, adaptation, response to stimuli, and reproduction. Essentially, life is an organized system capable of self-sustaining processes that allow for the continuation of biological functions.
