Myth

The hero Bellerophon tamed Pegasus and rode him against the Chimera, but tried to fly to Olympus; Zeus sent a gadfly, and the horse threw him.

Look for

The Great Square is a signpost of autumn skies. Count the stars inside it: under a good sky you will see a handful; under a city, none.

Discovery

In 1995 Michel Mayor and Didier Queloz found a giant planet whipping round the star 51 Pegasi every four days. It won them the 2019 Nobel Prize.
