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.

G3 may be hard to see due to weather patterns and the California wildfires, said Tim Brothers of the Massachusetts Institute of Technology.
