cosmic X-ray background

The cosmic X-ray background is a faint glow of X-ray radiation that fills the universe. It is primarily produced by the remnants of high-energy events, such as exploding stars and interactions between galaxies. When these energetic processes occur, they release X-rays that travel through space, creating a background that can be detected from Earth. Scientists study this radiation to learn about the universe's evolution, the behavior of black holes, and the distribution of matter in cosmos. Overall, it helps us understand the high-energy processes that shape the universe around us.
