The Eta Aquarid meteor shower is the legacy of Halley’s Comet in the May night sky

Do you remember Halley’s comet? The last time this famous object was visible was in 1986, 36 years ago.

Younger readers may remember little or nothing of this famous cosmic wanderer (it takes about 75 years to go around the sun once; your next chance will come in the summer of 2061). Or maybe, if you were out there at the time, you didn’t see Halley’s Comet at all due to light pollution or the comet’s low altitude above the horizon.
