astronomical event
Meteor shower, perhaps
An astronomical event is any significant occurrence or phenomenon observable in space or the sky, from eclipses and meteor showers to planetary alignments and supernovae.
These events range from predictable—like the annual Perseid meteor shower—to rare and unexpected, such as a comet's appearance.
We stayed up to watch the lunar eclipse, the most anticipated astronomical event of the year.
Amateur and professional astronomers alike track astronomical events, which can last from seconds to months.
