Astronomers Stunned by Age and Origin of Interstellar Comet 3I/ATLAS
Interstellar comet 3I/ATLAS may be up to 14 billion years old and comes from outside our solar system, offering unprecedented cosmic insights.
Scientists studying the interstellar visitor 3I/ATLAS say the object may be among the oldest ever observed, possibly dating back up to 14 billion years potentially older than our Sun. Unlike normal comets from within the solar system, this icy body’s hyperbolic trajectory shows it originated outside our star’s gravitational influence, likely from the Milky Way’s thicker stellar disk.
