Halley’s comet swings near Earth every 75 years. But debris left by the comet leads to two major meteor showers annually.

The Eta Aquarid meteor shower, one of the most striking annual celestial events, is expected to peak in May, offering skywatchers the chance to witness dozens of meteors streaking through the atmosphere.

Many Southern Hemisphere observers consider this shower to be the best meteor shower of the year, but it's a different story for Northern Hemisphere skywatchers.
