Black Holes: Crash Course Astronomy #33





It s exciting to think about setting up your own viewing station whether that is on the deck of your home or having a powerful but mobile telescope set up to take to the remove countryside to really get a good shot at some breath taking star gazing. The last thing we would want to do is to take away any of the fun of your hobby of astronomy because the joy of what we do as star gazers is a big part of the appeal. 

That constellation is The Big Dipper. Look to the northern sky on a clear night and widen your field of vision from just focusing on one star and it will pretty much jump out at you. In will look like a big kitchen pot or ladle, right side up in the fall, upside down in the spring. When you have the big dipper under control, you can pretty easily find the North Star. 

But for many of us, it was that first time we saw a rain of fire from the sky that we eventually came to know as a meteoroid shower. At the time when you see the first one, it s easy to remember the movie war of the worlds or some other fantastic image of aliens entering our atmosphere in droves to take over the planet. 

The thing that is most exciting about studying the universe is also the most frustrating and that is that no matter how expert we get, we are always just getting started. But if it s any consolation, some of the most advanced minds in science and from history always felt that way about space. Even the greats such as Copernicus and Einstein looked up into space and felt like they were just a spec in the presence of such infinity. 

But by far, the most talked about concept that has captured the imagination and the fears of science fiction fans and the general public is of another asteroid hitting the earth that could wipe out life as allegedly happened to the dinosaurs. In fact, the movie Armageddon was based on this idea and the concept that somehow mankind could avert that catastrophe with technology. 

Trying to make significant space exploration via telescopes from the terrestrial surface of planet Earth is very difficult. That very thing that keeps us alive, our own Earth s atmosphere presents a serious distraction from being able to see deeper and further into space. The Hubble space telescope was named after the great scientist and visionary Edward Hubble who discovered that the universe was expanding which was explained by what is now known in science as Hubble s Law.
