The cosmos is offering up a double feature in August: a pair of supermoons culminating in a rare blue moon.
The cosmos is offering up a double feature in August: a pair of supermoons culminating in a rare blue moon.
Catch the first show Tuesday evening as the full moon rises in the southeast, appearing slightly brighter and bigger than normal. That’s because it will be closer than usual, just 222,159 miles (357,530 kilometers) away, thus the supermoon label.
The moon will be even closer the night of August 30 — a scant 222,043 miles (357,344 kilometres) distant. Because it’s the second full moon in the same month, it will be what's called a blue moon.
“Warm summer nights are the ideal time to watch the full moon rise in the eastern sky within minutes of sunset. And it happens twice in August,” said retired NASA astrophysicist Fred Espenak, dubbed Mr. Eclipse for his eclipse-chasing expertise.

The last time two full supermoons graced the sky in the same month was in 2018. It won’t happen again until 2037, according to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project.
Masi will provide a live webcast of Tuesday evening’s supermoon, as it rises over the Coliseum in Rome.
