The Eta Aquarids meteor shower, originating from Halley's comet, is expected to peak on Tuesday, with better visibility in the southern hemisphere. While Europe can still see them, conditions are less favorable. Viewers can expect 10 to 15 meteors per hour in Europe and North America, compared to over 50 in southern regions. Optimal viewing occurs in the early predawn hours away from city lights, with the next major meteor shower occurring in late July.
