Deep Time: Crash Course Astronomy #45





To get started in learning how to observe the stars much better, there are some basic things we might need to look deeper, beyond just what we can see with the naked eye and begin to study the stars as well as enjoy them. The first thing you need isn t equipment at all but literature. A good star map will show you the major constellations, the location of the key stars we use to navigate the sky and the planets that will appear larger than stars. 

In modern times, we as people of science discount the astrological side and focus on the astronomy of the heavens. But they were one study for millennia before the age of science made them separate. There is historical evidence that astronomy was a recognized science as far back as the Babylonian civilization hundreds of years before Christ. 

All they have to know how to do is to look up. It really is amazing when you think about it that just by looking up on any given night, you could see virtually hundreds of thousands of stars, star systems, planets, moons, asteroids, comets and maybe a even an occasional space shuttle might wander by. 

So to get us off of first base, let s define some of the key terms that pertain to telescopes to help you be able to talk to them more intelligently. The first area of specialization in telescopes has to do with the types of telescopes people use. The three designs of telescopes that most people use are the Refractor, the Reflector and the Schmidt Cassegrain telescope. 

It was quite a revolutionary book because it also was the first scientific document to suggest that the earth was not the center of the universe and that astronomy should be focused strictly on the observation and recording of events in the cosmos. Over the next 2000 years, we have come a long way. Not only has science and religion completely gone their separate ways since Ptolemy but the science of astronomy makes tremendous strides every year that are so phenomenal, Ptolemy would be truly astounded. 

Moon Fever Of all of the celestial bodies that capture our attention and fascination as astronomers, none has a greater influence on life on planet Earth than it s own satellite, the moon. When you think about it, we regard the moon with such powerful significance that unlike the moons of other planets which we give names, we only refer to our one and only orbiting orb as THE moon.
