Black Holes, Aliens, and Asteroids


There isn’t enough time to cover every astronomy topic in Unit 5. But there was time for three more. Three of my favorites… black holes, aliens, and asteroids. Today in class, we went through a PowerPoint that discussed each of these fascinating topics. We started with black holes, a clump of matter so heavy and dense that its gravity will even suck in light. Then we moved on to alien life; to make a long story short, they’re out there! Lastly we discussed asteroids, the topic that is probably the biggest threat to Earth.
