Numbers
Astrophysicists apply their knowledge of maths to solve problems about the Universe. They collect information using telescopes, and use maths and statistics to interpret the information. Astrophysicists also use mathematical models and formulas to understand the physics of the Universe. We would not have been able to discover black holes or know that the Universe is expanding without maths.
Astronomers use numbers all the time (especially really big ones!). Astronomy grew out of solving problems about time and distance.
