Greenwich

The Royal Greenwich Observatory at Longitude 0 degrees. This point marks east from west and is used to calculate time worldwide.

I had to include this photo in the blog, being an amateur astronomer myself. It is part of William Herschels telescope who is an astronomy hero.

Here is what it used to look like before a tree fell on it.

Touching a meteorite.
