Did you know that every star you see in the night sky is a giant nuclear reactor? Stars like our Sun fuse hydrogen into helium in their cores, releasing immense energy through a process called nuclear fusion. This energy travels millions of kilometers to light up our skies and sustain life on Earth! And here’s the mind-blowing part—some stars are so massive, they end their lives as black holes, where gravity is so strong that not even light can escape! The universe is a wild place—stay curious!"
