3I/ATLAS Turns Blue Near Sun; NASA Models Struggle to Explain Non-Gravity Push

3I/ATLAS is the third confirmed interstellar comet, originating outside our solar system. As it approached the Sun, it displayed unusual activity: brightening, jets, color changes, and non-gravitational acceleration, likely caused by outgassing. While some speculated about alien technology, most scientists believe these behaviors are natural for comets. The blue color and other features can be explained by comet chemistry and solar effects. 3I/ATLAS offers a rare opportunity to study material from another star system, providing valuable insights into how comets form and behave beyond our solar neighborhood.
