Comet C/2024 S1 (ATLAS) is no more.

Monday (October 28), comet evaporated as it headed toward perihelion, the closest point to the sun in its orbit. It was previously hoped that the comet, officially designated C/2024 S1 (ATLAS), could become a “Halloween treat” visible to the naked eye, but ultimately these were just wishful thinking; astronomers had already begun to observe the cosmic snowball beginning to disintegrate earlier this month.

Now, thanks to the Solar and Heliospheric Observatory (SOHO), a spacecraft operated jointly by NASA and the European Space Agencywe know with certainty how and when comet ATLAS met its demise.
