Starwatch: Summer is the time to look for the constellation Sagittarius

The full constellation never rises above the UK horizon, but its most recognisable part, the teapot, will be visible

It's a good time of year to track down the summer constellation of Sagittarius, the archer, who is usually depicted as a centaur drawing a bow.

The chart shows the view looking south from London at 23:00 BST on 28 July, when the most recognisable portion of the constellation will be visible. Often called the teapot because of its distinctive shape, it fits into the larger constellation. The teapot's spout, as represented by the star Alnasl, depicts the arrow's sharp head in the full constellation. The lid and handle represent the upper body and outstretched arms.
