It is unlikely that dangerous cosmic rays will pass close to Earth tonight. Cosmic rays are high-energy particles that constantly reach Earth from outer space, but they are not typically associated with specific “close passes” like comets or asteroids. Earth’s atmosphere acts as a natural shield, protecting us from the majority of cosmic rays. While cosmic rays can pose a threat to astronauts and sensitive electronics in space, they do not usually pose an immediate danger to people on Earth. It’s always advisable to consult reliable sources such as space agencies or astronomy organizations for the most accurate and up-to-date information.
