🇬🇧🇨🇳 astrophysics - 天体物理学 : English Lesson

Meaning of "astrophysics" ("天体物理学"), detailed definition, and a short video lesson below.

Astrophysics is the science that tries to understand how space really works by using the rules of physics. Instead of just looking at stars and planets and saying, “Wow, that’s pretty,” astrophysics asks questions like: How hot is that star? Why does that planet move that way? What are black holes made of? Astrophysicists use math, telescopes, and ideas about forces, light, and energy to explain what stars, planets, galaxies, and other space objects are doing and why.
