Cosmic exploration refers to the scientific study and investigation of outer space, including celestial bodies like planets, stars, and galaxies. This field encompasses various methods, such as telescopes, space probes, and manned missions, to gather data about the universe's structure, origins, and potential for life. Key missions in cosmic exploration include NASA's Hubble Space Telescope, which has provided stunning images and valuable information about distant galaxies, and the Mars Rover missions, which explore the surface of Mars for signs of past life. These efforts help expand our understanding of the cosmos and our place within it.
