Tonight the Moon, Earth and Sun will fall into line to create a partial lunar eclipse. Between the hours of 8pm and 10pm, a small section near the top of the Moon will plunge into the Earth's shadow.
This event has been somewhat overshadowed (ha! ha!) by the Transit of Venus that occurs on Wednesday. But I must say, that I have a particular love of lunar eclipses. I think it's because they happen at night - so not only do you get to see the eclipse, but you can also check out the starry night sky.
The eclipsed Moon will be found below the constellation of Scorpius, at 9pm on 4 June (created using the Starry Night software).

This eclipse will occur in the eastern sky, with the Moon just beneath the constellation of Scorpius - one of the constellations that really is true to its name. Looking at the curving line of stars, it is easy to picture a Scorpion up there in the sky. And if you are away from city lights, then you'll see the brightest part of the Milky Way, which lies towards the Scorpion's tail.
The other great thing about lunar eclipses is that you don't need any special equipment at all to view them. Just a clear night sky and the willingness to spend some time outdoors, marveling that we are part of a much larger Universe.
