The highlight this month is Jupiter, rising in the South-East at sunset before commuting towards the South-West overnight. Take a look through binoculars and you will be able to see up to four moons around the planet. Take another look just a few hours later, and you may notice that the moons have moved slightly in their orbit around Jupiter.

August should be an exciting month. There will be a meteor shower and a partial lunar eclipse. On the night of the 11th the Perseid meteor showers will be at their peak, radiating from a point in Cassiopeia in the north-east. They can best be seen after 12.30 pm when the Moon has set.
The partial lunar eclipse occurs conveniently at 8.40 pm on Saturday August 16, 15 minutes after sunset in London and half an hour after moonrise. The eclipse will continue until 11.40 pm. At its peak some 80 per cent of the lunar surface will be in shadow.

August skies are filled with the glittering eyes of distant suns, as the heart of the Milky Way wheels into view for its annual visit.
Our solar system lies on an arm of the spiral galaxy we call home, far removed from its brilliant core of gas, dust and innumerable stars. From this vantage point, we get a beautiful wide-angle view of the galaxys centre. This vista is best enjoyed from the southern hemisphere, or at least thats what I hear. At some point before my body returns to stardust, Id like to get a look at the real thing.

The moon's shadow swept across the planet from Canada to China on Friday, delighting throngs of skywatchers who flocked to see a total eclipse of the sun.
The stellar spectacle which arises when the moon passes directly between the sun and Earth began in northern Canada, tracked across Greenland and the Arctic, then moved through Russia and Mongolia.
