Comet Neowise is passing Earth for the first time in almost 6,800 yearsThe cosmos are concluding a spectacular month of celestial events with a double feature: two meteor showers peaking at the same time. The southern Delta-Aquariids are active every year from around July 12 to August 23, according to NASA. This year the meteor shower is peaking on Monday, July 27 into Tuesday and Wednesday. If you can't spot the showers, look for them again during the Perseids meteor shower in August, when they will still be visible. While Perseids — the most spectacular meteor shower of the year — is currently active, its peak won't come until next month.
