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害羞草研究所檚 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 Aug. 30 害羞草研究所� a scant 222,043 miles (357,344 kilometers) distant. Because it害羞草研究所檚 the second full moon in the same month, it will be what害羞草研究所檚 called a blue moon.

The last time two full supermoons graced the sky in the same month was in 2018. It won害羞草研究所檛 happen again until 2037, according to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project.

Masi will provide a live of Tuesday evening害羞草研究所檚 supermoon, as it rises over the Coliseum in Rome.

害羞草研究所淢y plans are to capture the beauty of this 害羞草研究所� hopefully bringing the emotion of the show to our viewers,害羞草研究所� Masi said in an email.

害羞草研究所淭he supermoon offers us a great opportunity to look up and discover the sky,害羞草研究所� he added.

This year害羞草研究所檚 first supermoon was in July. The fourth and last will be in September. The two in August will be closer than either of those.

Provided clear skies, binoculars or backyard telescopes can enhance the experience, Espenak said, revealing such features as lunar maria 害羞草研究所� the dark plains formed by ancient volcanic lava flows 害羞草研究所� and rays emanating from lunar craters.
