A lunar eclipseoccurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra. When the Moon is within the umbra, it will turn a reddish hue. Lunar eclipses are sometimes called “Blood Moons” because of this phenomeno...

The Moon will be in the constellation Libra. Here are some more skywatching tipsfor the month of May.
The same phenomenon that makes our sky blue and our sunsets red causes the Moon to turn red during a lunar eclipse. It’s called Rayleigh scattering. Light travels in waves, and different colors of light have different physical properties. Blue light has a shorter wavelength and is scattered more easily by particles in Earth’s atmosphere than red li...
NASA’s mission team for the Lunar Reconnaissance Orbiter (LRO), NASA’s spacecraft in orbit around the Moon, will turn the instruments off during the eclipse. The spacecraft is solar-powered, so LRO will power down to preserve its battery while the Moon is in shadow. The Lucy spacecraft, currently on its journey to study Jupiter’s Trojan asteroids, ...
