Let’s Begin…

The planets in our solar system are made up of varying formations of rocks, water (ice), and gases. Scientist have figured out where most of these materials come from except water. This led to more research and eventually ...the question: "Did water come from a galaxy far, far away? Realizing that water just wasn't here from the beginning, they had more discovering to do to explain its origins.

Additional Resources for you to Explore
There is so much scientific content to share about the planets. NASA does an excellent job at curating info from global experts and shares it in one space(pun intended).If you want to broaden your research then the main NASA site might be right for you.Since we are a great big global family of learners, The European Space Agency hosts a wonderful website dedicated to children too.Since there is so much happening beyond our atmosphere, let's not leave out some information about comets and asteroids. Here is the Canadian Space Agency's Asteroids page with more mind info for you. Make sure you scroll down to see the excellent graphic comparing everything from comets to meteorites to fireballs.All of this learning about water leads me to this question. Are there creatures on Earth that are better equipped to go without water than others? This BBC Earth page explains that there are many.
The more I learn about space and our solar system, the more I realize the vastness of it all. It is so difficult to ponder the cosmos and more often than not, I am in awe of the scientists that have made it their life's work to explore and explain it. Whether it is through technological advancements, space flight, or astronomy the beauty and deeper understanding of space is now only a few clicks away for those of us staying on terra firma. As a child, I dreamt of going to space like the astronauts on the Apollo missions, and then it was the Space Shuttle. As those dreams faded, I maintained a deep interest in the astronomy, physics, and engineering involved in the study of space. I am excited to see what is next as we continue our global pursuirt to explore beyond our terrestrial borders. One thing is for sure, I hope there is water.

Water, sun and air are all vital to the survival of every living thing on Earth. Very few species would live long with out them. What other things from nature do you think are important to our survival too? Why?
