A NASA image of a pyramid-like structure in Mars' Candor Chasma has sparked renewed debate over ancient alien life, though scientists say natural processes likely formed it.
A recently released NASA image of a pyramid-like structure in Mars' Candor Chasma has reignited public debate over potential ancient alien life.
First spotted in 2001 by researcher Keith Laney, the three-sided formation's symmetry has led some, including filmmaker Brian Dobbs and researcher George Haas, to suggest it may be artificial.
While NASA has not confirmed any non-natural origin, the structure's shape has fueled speculation despite scientific consensus that natural geological processes are the most likely explanation.
No evidence of extraterrestrial life or civilization has been found.
