NASA is America’s space agency, but that is not all. A lot of people forget that the first A in NASA stands for Aeronautics. NASA is the National Aeronautics and Space Administration. They do more than just launch rockets. NASA is also involved in aeronautical research. They work to develop […]

Here’s another non-astronomy entry.
70 years ago today, the era of the great airships came to an end. Yes, Zeppelins (giant rigid airships) continued to fly for a few years, and airships still fly today in the form of blimps (smaller non-rigid airships). But the large rigid airships would never again […]

Visual light is only a small part of the electromagnetic spectrum. While historically astronomy started with observations of visual light, that really doesn’t see everything that there is to see out there. Many objects emit primarily infrared light, radio waves, X-rays, or any of the other wavelengths of electromagnetic radiation. And, a […]

Yesterday, the F-35 Lightning II Joint Strike Fighter flew its first test flight. Besides really liking aircraft, it was interesting to me because they are building the things just a few miles from where I live, and the test flight was also just a few miles from my home. Prototype aircraft have […]

Well, if you are outdoors doing astronomy, eventually you see all sorts of things in the sky. And, there’s always something new that you’ve never seen before. Last night was one of those nights.

This weekend there was an airshow near where I live (so close that you could hear the jets if you were outside). Well, yesterday I decided to take a day to just have fun, so I went to the airshow. It was as interesting as such things always are. However, the crowds […]

I had an idea to write about cosmic rays and cosmic ray exposure, but this post turned out to be a much larger project than I thought. Below you will find information about cosmic rays themselves, as well as the exposure that airline crews experience due to cosmic rays.
A century ago, scientists were just […]
