Michigan State University and NASA researchers discover seven dark comets that reveal new solar system secrets.

The so-called 'planetesimal belts' are filled with tiny millimeter-sized particles created by collisions between comets.

Comet ATLAS (C/2024 G3) came within 8.3 million miles of the sun on January 13 as it reached its perihelion, and is now disintegrating.
