The Moon and planet Jupiter

This morning the Moon and planet Jupiter (The little bright dot next to the church tower) had an relatively close encounter, at least from our point of view here on Earth.

The distance to the Moon and Jupiter varies, this morning planet Jupiter was about 1,800 times further away than the Moon. It took the light from the Moon about 1 second to reach my camera, but the light from Jupiter had traveled for almost 40 minutes.

So watching pictures like this is like traveling with a time machine. The old Church tower is present time, watching the Moon we have traveled 1 second back in time and when watching Jupiter we have traveled 40 minutes back in time.

So when this light left Jupiter, I was back home and enjoyed my breakfast. It's things like this that make space so cool :-)
