As someone who has been an enthusiastic amateur astronomer and photographer for the last 50 years, I have learned that the universe is a very colorful place. Even without a telescope, it’s apparent that the planet Mars and the star Antares are brilliant reds. With a short time exposure using only a normal camera, more colors appear, like the contrasting red and blue bright areas in Orion’s sword.

The part of the electromagnetic spectrum visible to the human eye is quite small. The infrared portion, whose light the Webb telescope collects, is a lot wider. It encompasses a large number of wavelengths. The use of algorithms that add color to that data to help visualize what is out there in no way diminishes the “reality” of the photographs.

A picture of the “Stephan’s Quintet” of galaxies, shown in one of the photos from the new telescope, was used in the almost 80-year-old movie, “It’s a Wonderful Life”. I took a screen grab of the old black-and-white picture from the movie, and made this video comparison with the brand new image.

Color enhancements aside, there’s no denying the huge technological strides that have allowed for much sharper detail and revealed many more objects than old earthbound telescopes. That’s as real as it gets.

I thought the Feder interview was excellent, even more so because he was allowed to edit his own words.

I like the Table of Contents w/links. I do scan the entire newsletter when I first open it and having the links to look at specific content afterwards is nice.
