#4b: Let There Be First Light!, by medicat

This image tied with the Venus transit, and it involves our sister planet as well. But this time, instead of the Sun, the larger object is the Moon: Occasionally, the two line up in the sky providing us with this amazing view of objects that are actually separated by tens of millions of kilometers.

By coincidence, this conjunction happened when both the Moon and Venus were in the same phase; the distant planet mimicking the far closer Moon. Note how dark the Moon is compared to Venus: On average Venus reflects five times as much sunlight as the Moon.

And making this picture all the more remarkable: It was the first observation for the telescope used!
