27 August 2018 Ade Ashford

If you’ve never seen a comet, there’s currently a bright example visible in the late evening about to make a close approach to the 6th brightest star in the night sky on the UK night of 2–3 September. We show you how to find Comet 21P/Giacobini-Zinner around the time it passes within a degree of prominent star Capella.
