Why astronomy? :
When I was little, I saw pictures of stars in an astronomy book and thought they were beautiful. Later, one of my relatives told me, “The light from the stars you see now was emitted a long time ago.” I was fascinated by the sheer scale of the universe, where even light can take years to reach us.
