Astrophysical sources

Astrophysical sources are natural cosmic objects or events that emit energy or signals detectable from Earth. Examples include stars, black holes, galaxies, supernovae, and pulsars. These sources produce various forms of radiation—light, X-rays, radio waves—and particles that help scientists study the universe’s composition, evolution, and physical laws. Understanding astrophysical sources allows us to learn about extreme conditions, the lifecycle of celestial objects, and the fundamental processes shaping the cosmos. Essentially, they are the universe’s natural laboratories, providing insights through the signals they send across space.
