Jets

Jets are high-speed streams of particles, mainly electrons and protons, that are ejected from energetic astronomical objects like black holes, neutron stars, or active galactic nuclei. They are propelled by powerful magnetic fields and occur when material accretes onto these objects. Jets can extend thousands to millions of light-years into space, emitting strong radiation across the electromagnetic spectrum, especially in radio and X-ray wavelengths. They play a significant role in galaxy evolution by influencing their surroundings through energy and matter transfer. Jets are fundamental in understanding cosmic processes involving extreme gravity, magnetic fields, and high-energy physics.
