In a twist of cosmic fate, a comet dubbed the "Halloween comet" met its end on Monday. Discovered on September 27 by an Asteroid Terrestrial-impact Last Alert System in Hawaii, this icy, gaseous, and rocky celestial body had sparked interest for its potential visibility during Halloween. However, as it approached its closest point to the sun, known as perihelion, the comet began to break apart, ultimately vaporizing. The European Space Agency and NASA's Solar and Heliospheric Observatory mission captured this dramatic event.

Comet C/2024 S1 was a sungrazer, a type of comet that passes close to the sun. These comets often face the sun's intense heat, which can cause them to disintegrate. Astronomers had been divided on whether this comet would survive its journey. Karl Battams, a computational scientist at the Naval Research Laboratory, explained that sungrazing comets are particularly challenging to predict.

The comet reached its perihelion on Monday morning, coming within 1% of Earth's distance from the sun, less than 1 million miles away. This proximity led to its complete vaporization. In contrast, another comet, C/2023 A3 Tsuchinshan–ATLAS, survived its perihelion in September but is no longer visible to the naked eye.

Sungrazing comets rarely survive their close encounter with the sun. The NASA Sungrazer Project, led by Battams, has discovered over 4, 000 such comets, none of which have survived their perihelion. Notable exceptions include comet C/2011 W3 Lovejoy, which managed to survive in 2011.

Between now and 2030, only three comets are expected to be visible without a telescope. While there might be undiscovered comets that could become visible, the Halloween comet, part of the Kreutz family of comets, will not produce any meteor showers. Its fate serves as a reminder of the unpredictable nature of comets and the challenges of studying these celestial bodies.
