Huge, deep hole on Mars leaves scientists baffled
A depression huge and deep on Mars has left astronomers baffled.According to NASA, “the depressions are thought to be caused by sublimation, which is when a material goes directly from a solid to a gas phase.”According to Science Alert, there are many ways such holes are formed on Mars, which is colder than Earth— meteorites leave craters;
lava tubes collapse and produce deep pits; floods from long ago hollow out grand canyons; and volcanos melts ice fashioning funnels.The depression was discovered by the MRO's High Resolution Imaging Science Experiment, or HiRISE camera, which allows NASA to see Martian objects larger than 3 feet from about 125 to 250 miles above.

The camera takes repeated images throughout Mars’ seasons to monitor the terrain’s changes.
