Lunar eclipses happen every six months. They are total, partial or penumbral. On Jan. 20, we will see the next total lunar eclipse! This is when the moon moves completely into Earth’s shadow and appears dark red. Partial eclipses are when part of the moon moves into Earth’s shadow and appear to have a piece missing. Penumbral eclipses are when the moon is in the area where some of the sun’s light is blocked and it appears less bright than most full moons.

Details for this eclipse: penumbral begins at 8:37 p.m., partial begins at 9:35 p.m., totality begins at 10:42 p.m. and ends at 11:44 p.m., and partial ends at 12:50 a.m. on Jan. 21 (times are Central Time).

Weather permitting, the observatory will be open to view the eclipse. We hope you can join us for this event or for our Public Nights on the first Friday each month, from sunset to 10 p.m.:
