Stargazers in the UK have an opportunity to spot Sagitta, also known as 'the arrow', in the northern summer sky. Despite being the third-smallest constellation, its distinctive arrow shape makes it relatively easy to identify against a dark backdrop.
Sagitta can be located partway along the imaginary line that connects the stars Vega and Altair, which form part of the summer triangle alongside Deneb. Observers in London can view it by looking up towards the zenith while facing south at 10:30 PM BST on Monday.
The constellation has been recognised since ancient times, with the 2nd-century astronomer Ptolemy including it in his list of 48 constellations. Greek mythology offers several potential origins for the arrow, including one fired by Hercules or one of Cupid's arrows.
Those in the southern hemisphere can also observe Sagitta during August, though it will appear lower in their northern sky compared to its visibility from the UK.
