Go outside and look up at the beautiful clear autumn night sky.
With apps like stellarium (or pocket universe) simply point your phone at the sky to identify stars, planets, nebula, start clusters, etc.
A great way to get into star gazing and a great guide to identify objects for closer look if you have a good set of binoculars or a small telescope.
Also try ISS Spotter (https://apps.apple.com/au/app/iss-spotter/id523486350) to find out the best time to see the International Space Station pass overhead.
