In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

In this illustrated math problem, students use pi to compare the area of the Hubble Space Telescope and Webb Telescope’s primary mirror.

In this illustrated problem set, students use pi to calculate the size of a Mars rock sample, compare the mirrors of two space telescopes, deduce an asteroid's makeup, and size up a solar eclipse.

In this illustrated math problem, students use the mathematical constant pi to calculate how far the TESS spacecraft travels as it sends data to Earth.

Students will learn about the expanding universe and the redshift of lightwaves, then perform their own calculations with a distant supernova.

In this illustrated math problem, students use pi to calculate the distance across a disk of debris around the star Beta Pictoris.

In this illustrated problem set, students use pi to reveal the size of a planet outside our solar system, find out how much helium is raining out from Jupiter's cloud tops, locate a seismic event on Mars and study an interstellar object detected in our so

In this illustrated math problem, students use pi and data from the Kepler space telescope to find the size of a planet outside our solar system.
