Here’s an image of the moon’s crater, Tycho, that I took in March of this year (Tycho is the bright crater in the center of the picture). Tycho is about 50 miles in diameter and it is very young – only around 108 million years old! There are other craters on the moon that are almost 4 billion years old, so Tycho is a mere baby compared to those senior citizens of the lunar landscape. Tycho was formed as a result of another celestial body hitting the moon at that spot, and with binoculars you can see “rays” of bright material that has been thrown far away from the impact site.
Tycho has a role in the science fiction movie 2001: A Space Odyssey, since it is the location where modern humans find an alien machine (or “monolith”) buried in the crater.
I’ve always been interested in the night sky, and I can remember receiving my first (toy) telescope when I was about six years old. While my interest in astronomy increased in high school, I only started getting seriously into astrophotography – a hobby that combines astronomy and photography – about 10 years ago. Since then I’ve taken pictures of the sun, moon, planets and “deep sky” objects, all of which I would like to share with you. The hobby has come a very long way since I started looking through a telescope many years ago!
