Moon and planets

On the night of May 19th the Moon appeared to pass very close to Venus, it was a beautiful sight just after sunset. Unfortunately as the Moon was fairly new, it necessarily set not long after the Sun, and seen from the UK had not reached its closest approach before setting. This picture is from earlier on in the evening. The Moon is sneaking up on Venus, in preparation for giving it a wedgie.

Closer shot of the crescent Moon. Note how the low-angled morning light shows craters in deep shadow along the terminator. That is just an astronomickal term, there is not a killer robot from the future living on the Moon. Or at any rate if there is, it is not visible in this photo.

Jupiter is high and bright in the south at the moment, and I got this nice picture from my cosy living room with just the 200mm telephoto. It is no trick to be able to see Jupiter, as it is genuinely awesome in size, bigger than all the other planets put together, twice, and a bit more, but I was pleased to be able to see the four principal moons as well: from left to right, Callisto, Ganymede, Io and Europa.

If you looked at the Solar System from far away, you would conclude there was one main planet, Jupiter, plus some annoying specks. Jupiter has more moons than the Sun has planets (over 60 at last count), but then it acts like a giant Dyson, vacuuming up any asteroids and comets that wander too close, with no loss of suction! In 1994 the Shoemaker-Levy 9 comet hit Jupiter, creating an explosion about the size of the Earth, and seriously denting its no-claims bonus.

If you expose for its moons, Jupiter is just a bright blob, so here is a picture attempting to show detail of the planet itself. You can see its coloured bands and stripes, especially the large white equatorial zone. It is sometimes said that Jupiter is a failed star, and in Arthur C. Clarke’s novel 2010 it is turned into a star by some helpful people from a black monolith. This would be convenient for us here on Earth as it would provide valuable light to see by at night, and deter burglars. In reality though that would not happen, as Jupiter is a long way short of enough mass to kick-start nuclear fusion, but on the other hand if you have a giant black monolith you can do basically anything.
