Scientists have identified an interstellar comet older than the Sun, challenging current understanding of its origins. In Chile, a robotic telescope detected a moving object on July 1st, which led to a surprising revelation – it’s not just a regular solar system visitor but a wanderer from another star in the Milky Way.
This rare discovery puts a new branch of astronomy to the test, as astronomers seek to understand the formation and behavior of such objects. The comet is believed to have formed around a distant star elsewhere in the galaxy, showcasing the vast complexity of our cosmic neighborhood.
