You might have heard that they found another chamber in the Great Pyramid recently. Archaeologists and physicists did this by using muons–a type of subatomic particle–to see inside the rock.
Here’s how they did it:
There is another way muon tomography is helping scientists keep people safe: by looking through volcanoes.
Unfortunately, the last online bulletin of the volcano observatory at Guadeloupe (English translation of website here) is from 2014.
I hope the Great Pyramid discovery may encourage more volcanologists around the world to check out the technique!
