Difference between Galaxy and Optical telescope

Galaxy vs. Optical telescope

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors.

Similarities between Galaxy and Optical telescope

Galaxy and Optical telescope have 11 things in common (in Unionpedia): Active galactic nucleus, Ancient Greek philosophy, Angular diameter, Electromagnetic spectrum, Galileo Galilei, Hubble Space Telescope, Ibn al-Haytham, Moon, Nebula, Sun, Visible spectrum.

Active galactic nucleus

An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much higher than normal luminosity over at least some portion—and possibly all—of the electromagnetic spectrum, with characteristics indicating that the excess luminosity is not produced by stars.
