• Ancient interstellar object 3I/ATLAS offers first glimpse into thick disk comet chemistry

    Interstellar comet 3I/ATLAS, first observed by the ATLAS survey in Chile on July 1, 2025, is the third confirmed object of its kind to enter the solar system. Analysis of its hyperbolic trajectory and inbound velocity of ~58 km/s confirms its extrasolar origin, while kinematic modeling suggests it formed in the Milky Way’s ancient thick disk, offering a rare opportunity to study early galactic comet chemistry.

  • Extremely rare gigantic jet captured from the International Space Station over Mexico and U.S. Southwest

    An extremely rare gigantic jet, powerful bolt of upward lightning, was captured from the International Space Station as it soared above a thunderstorm over northern Mexico and the U.S. Southwest on July 3, 2025. The striking image, taken by NASA astronaut Nichole Vapor Ayers, shows the jet piercing into the ionosphere, offering a rare glimpse of one of Earth’s most elusive atmospheric phenomena.
