XMM-Newton

XMM-Newton is a space-based observatory launched by the European Space Agency to study X-ray radiation from celestial objects. It orbits Earth and uses advanced telescopes and detectors to capture high-energy signals from phenomena like black holes, neutron stars, and galaxies. By analyzing these X-rays, scientists can understand the physical processes occurring in extreme environments, providing insights into the universe's structure, evolution, and the fundamental physics governing it. XMM-Newton's observations help expand our knowledge of cosmic events that are invisible in visible light.
