Deep space exploration refers to the study of regions in space that are far beyond our solar system. This includes investigating distant stars, galaxies, and cosmic phenomena. Scientists use advanced technology, such as telescopes and space probes, to gather data about these areas, helping us understand the universe's origins and structure. Missions like the Hubble Space Telescope and Voyager spacecraft have provided valuable insights into deep space. These explorations help answer fundamental questions about the existence of other planets, the potential for life beyond Earth, and the overall evolution of the cosmos.
