Space is not just "space". There are gas particles, dust particles and pieces of atoms and molecules floating continuously...because of inertia. Most of the materials are hydrogen and helium. From these materials our Sun was formed and other Suns as well. "A star the size of our sun requires about 50 million years to mature from the beginning of the collapse to adulthood," according to NASA. "Our sun will stay in this mature phase … for approximately 10 billion years." The question is: How did the Sun form in the first place? The Star Nebula Theory explains one way this is possible. The theory presents as a cycle. Like the water cycle. Or the carbon cycle. Or the frog cycle. Matter cannot be created or destroyed... Our sun is an average star. The materials left over from the formation of our sun created the planets, comets, meteoroids and and asteroids still in our solar system. Our solar system time line: Astronomers are finding nebula's, lots of nebula's out in space. Does this mean they are star factories? Churning out stars of all different sizes and mass? Possibly.... Astronomers love looking for them...and I love looking at them. Each are unique and beautiful.

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
