Why Stars?
Throughout history, many civilizations have been fascinated by the stars in the night sky. But the question is why. Why have many civilizations been fascinated by stars? What makes the night sky so attractive to humans? Why did they ascribe meaning to tiny dots that shone brightly, and seemed so far away? I present the […] Continue reading
Blog 4 – Weather vs. Climate
There is often a lot of confusion when we talk about weather versus climate, and the impact both have on our planet. Many people who deny climate change/global warming do so because they are confused between weather and climate.

What color is the Sun? (not yellow)
by me The Sun is the brightest and biggest celestial body in our solar system. Its diameter is 865,000 miles, which is about 110 Earths long. Without the Sun’s light, there would be no life on Earth. The Sun is so important to us humans, yet some people don’t take the time to appreciate its […] Continue reading

But the frontier of space presents a distinct challenge from previous frontiers — it is simply SO large. Large enough, in fact, that for the first time in the […] Continue reading
The Cosmic Spin-off That Created Our Solar System
Alright, let’s dive into how our solar system came to be, and trust me, it’s quite the cosmic tale. Picture this: over 4.5 billion years ago, the universe decides it’s time for a little creation project. So, in a neighborhood of our Milky Way galaxy, a giant cloud of gas and dust, known as a […] Continue reading
Nature’s Closely Guarded Secret – Nuclear Fusion
We are, quite literally, made of stardust. Stars are the birthplace of many of the elements that make up our physical reality as we know it. Heavier elements (heavier than Iron, specifically) were created in a Supernova — a violent explosion of epic proportions at the end of a massive stars life. Inside of every […] Continue reading

Carbon Dating
Ever wonder how we know how old dinosaurs were? Or how long humans have been on the Earth? Well, it all comes down to a technique that scientists use called carbon dating. The process starts with the Sun’s radiation colliding with a N-14 causing a proton to fall off and creating C-14. This C-14 reacts […] Continue reading
