At our December meeting I shared a video from the Minnesota State University at Moorhead Planetarium speculating on possible explanations for the Star of Bethlehem. i also referenced a second video from the BBC Sky At Night program on the same topic. They came to different conclusions, see what you think.

The Chicxulub Asteroid
Sixty-six million years ago, the dinosaurs looked up from their world-domination and saw something plunging from the sky. They couldn’t have known it, but their world was over. Here are a few links about current findings and theories of that day:
- The New Yorker magazine, March 29, 2019 – this article discusses the possibility that a paleontologist may have found a large fossil trove from the actual day that the asteroid hit:
- A BBC article that essentially summarizes the New Yorker article
- A Space.com post that discusses the idea that it was an asteroid that struck
- A Harvard Gazette article from February 2021 that instead theorizes a comet from the Oort Cloud smashing into the Earth
- A Livescience.com post that talks about what probably happened in the moments and hours following the impact
- And if you ever wondered how and why cockroaches survived the impact (which of course they did – they were there before it hit, and are still with us), here you go.

Chankillo is a solar observatory in northern Peru that’s over 2500 years old. It’s now been named a UNESCO World Heritage Site. There’s a good description of the site and how it may have been used here, including descriptions of the thirteen towers that were integral to it’s purpose.
