Keplerâ€™s First Law of Motion - Elliptical Orbits (Astronomy)
This is certainly true in astronomy both in terms of terms that refer to the cosmos and terms that describe the tools of the trade, the most prevalent being the telescope. 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.
In the English language, the first two days or our week, Sunday and Monday are a reference to astronomy as their literal interpretations would be The Day of the Sun and The Day of the Moon. So if you have found astronomy becoming a consuming passion in your thoughts and what fascinates you about the world we live in, you are in great company as this area of study has been a major part of culture and thought virtually since the dawn of civilization.
These little fun facts should get a pretty spirited discussion going about the origins of the universe and about the possibility of space travel or if there are life on other planets. You can challenge the kids to calculate that if every star in the Milky Way supported nine planets and if only one of them was habitable like earth is, what are the odds that life would exist on one of them?
Other than the Olympic movement, international cooperation to achieve great strides for human kind in space seems to go forward without interruption even when the nations cooperating in those projects are virtually at war back on the surface of the earth. It is a strange thing to watch as Russian, American and other astronauts work together like brothers on space missions even as their home nations are busily pointing missiles at each other back at home.
That trailing plume is what makes up the comet s magnificent tail that makes it so exciting to watch when a comet comes within view of Earth. The origins of comets is similarly mysterious. There are a number of theories about where they come from but it is clear that they originate from outside our solar system, somewhere in deep space.
There are many objects floating around in our solar system other than the planets we know of. It s an interesting piece of trivia that in addition to the planets there are 165 moons orbiting around those nine planets. Some of those moons are so advanced that some scientists have suspected that they might have supported life at some point.
