This month’s ‘blood moon’ eclipse to be the longest of the century
NASA explains the entire event will go on for about four hours, while the ‘blood moon’ phenomenon itself will be visible for an hour and 43 minutes at its peak.
July is a busy skywatching month. Our top picks:-Earth at aphelion on the 6th,-A grazing occultation of Aldebaran by the Moon for the Great Lakes on the 10th,-A partial solar eclipse for Tasmania on the 13th,-Mars at opposition & a total lunar eclipse July 27th. More to come! pic.twitter.com/HyyA9Bo40J

A blood moon takes place when Earth blocks the light of the sun from the moon. Some light does get around our planet’s atmosphere, lending the moon a reddish-brown hue. The air around Earth scatters more of the short-wave light, like green and blue, than the longer wavelength light, which is on the red end of the spectrum.
Not everyone will be able to see the long-lasting lunar spectacle, however. While people in Africa, Asia, Australia, Europe, New Zealand and South America will be able to enjoy the eclipse, those in North America won’t be so lucky. On the bright side, the lunar eclipse doesn’t take place for a few weeks, on July 27, so there’s enough time to book a flight to check it out!
