Comet 332P/Ikeya-Murakami

Observed in 2016

This remarkable image reveals the ancient comet 332P/Ikeya-Murakami in the dramatic process of disintegrating as it approaches the Sun, providing one of the sharpest views ever captured of an icy comet breaking apart. Comets are fragile objects composed of ice, dust, and rocky material left over from the solar system's formation over 4.5 billion years ago. As they venture close to the Sun, solar heating causes their ices to vaporize and internal stresses can tear them apart, especially if they have been weakened by previous passages or structural flaws. The disintegration of 332P offers astronomers a rare opportunity to study the internal structure and composition of these primordial frozen bodies. The fragments visible in this image will continue to drift apart along the comet's orbit, gradually dispersing into space and potentially creating meteor showers if Earth's orbit intersects their debris stream in the future.
