Deep space refers to the vast regions of the universe that lie beyond our solar system. It includes areas far from the gravitational influence of stars and planets, where the density of matter is extremely low. This region is home to galaxies, nebulae, and other celestial phenomena, making it a key area of study for astronomers. Exploring deep space helps scientists understand the origins and evolution of the universe. Instruments like the Hubble Space Telescope and the James Webb Space Telescope are used to observe distant objects, providing valuable data about the formation of stars, galaxies, and the potential for extraterrestrial life.
