Stargazers will be in for another celestial treat Tuesday night as three cosmic events will occur at the same time during the full moon.
After last month brought space enthusiasts a blue supermoon, September’s harvest moon will not only coincide with a supermoon, but also with a blood moon and partial lunar eclipse.
While harvest moons happen each year close to the start of fall and supermoons three to four times a year, all three events taking place at the same time are “quite rare,” astrophysicist Teresa Monsue of NASA’s Goddard Space Flight Center told NPR.
The moon is considered “super” when it is full and its orbit is at the closest point to Earth, according to NASA. When the Earth is positioned between a full moon and the sun, and the moon passes through Earth’s shadow, a lunar eclipse takes place.
