Is the Moon unchanging?

28. April 2011, 11.20
Ever since the discovery of the telescope, man has been fascinated by the observation of the surface of the Moon. The constantly changing light coming from the Sun causes craters, mountains, valleys and plains to take on continuously varying appearances. Yet, as we look at this atmosphereless natural satellite, we get the impression that the Moon has not changed, even over the span of a human lifetime. But is this really the case?

Biggest full Moon in over 18 years

25. March 2011, 11.43
On 19 March 2011 everything came together perfectly – in a completely clear sky there was a full Moon and, what is more, at almost the exact time, the Moon passed through the point of closest approach to Earth on its elliptical orbit. This meant we were able to admire an unusually large and bright full Moon. Not wanting to let this opportunity pass, I photographed the Moon through my telescope.
