Sun's Heat Ends Comet ATLAS's Journey Early

Imagine a comet swooshing through space, expected to brighten up our nights around Halloween. Sadly, Comet ATLAS didn't make it. It got too close to the sun and melted into nothing. It's like when a popsicle melts in your hand on a hot day, but on a way larger scale. Comet ATLAS, first spotted in September, was special. It belonged to a group of comets named after an astronomer who studied them, Heinrich Kreutz. These comets, called sungrazers, get really close to the sun. Sometimes, they're visible from Earth. But often, they don't survive the journey. The sun's heat and gravity are just too much.

Scientists captured the melting moment with NASA's Solar and Heliospheric Observatory. Just 750, 000 miles from the sun's surface, Comet ATLAS disintegrated. It might have been big and bright, maybe even outshining Venus. But that close encounter with the sun was the end of its voyage. These sungrazers are thought to be pieces of a larger comet that broke apart ages ago. While some can be seen from Earth, many don't survive the sun's intense heat. It's a sad end, but it's also a reminder of the powerful forces at work in our solar system.
