The 16 students from teacher Dennis Mitchell's 7th-grade science class at Evergreen Middle School in Cottonwood, Calif., found what looks to be a Martian skylight — a hole in the roof of a cave on Mars.
The intrepid students were participating in the Mars Student Imaging Program at the Mars Space Flight Facility at Arizona State University. The program allows students to frame a research question and then commission a Mars-orbiting camera to take an image to answer their question.
