ASTRONOMICAL EVENTS

2020'S METEOR SHOWERS by Jay Chesters

From October through December there are several key meteor showers before the end of 2020. Starting with the faint and fast Orionids in October, through to the bold and bright Geminids in December there's lots happening in the sky. Thanks to some fortunate moon phases, we're also looking forward to dark skies. Get away from the city lights, find somewhere dark, then sit back and watch the skies.

Read on for the key facts.
