The first total lunar eclipse in more than two years coincides with a supermoon this week for quite a cosmic show. Better look quick: the total eclipse will last about 15 minutes as Earth passes directly between the moon and the sun. Circling the moon for 12 years, the orbiter will measure temperature changes on the lunar surface during the eclipse. This will be a nearly total eclipse where the moon dims but doesn’t turn red. The next total lunar eclipse will be May 2022.
