Definition Of Galaxy In Science, A galaxy is a physical system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. Their distribution isn’t random, as one might Our home galaxy, the Milky Way, is a barred spiral galaxy spanning roughly one hundred thousand light-years. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a thousand stars, to the largest galaxies known – supergiants with one hundred trillion A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity.
