A near-total lunar eclipse will be visible across the U.S. Thursday night
Two weeks after a total solar eclipse wowed skywatchers in southern Europe, a near-total lunar eclipse is set to put on a show Thursday night for people across North and South America.Lunar eclipses occur when Earth slips between the sun and the moon and casts a shadow on the lunar surface.During this week’s event, nearly the entire moon — 96.2% at the eclipse’s peak — will be shrouded in Earth’s shadow.Weather permitting, skywatchers in the continental U.S.
will have some of the best views.The eclipse will also be visible elsewhere in North America, South America, parts of Europe and Africa.During the eclipse, Earth’s shadow will appear reddish orange on the lunar surface because of the way Earth’s atmosphere scatters light from the sun.
That’s why a total lunar eclipse is also known as a “blood moon.”Thursday’s eclipse will begin at 9:23 p.m.ET, when the moon first enters the outer part of Earth’s shadow.

ET, when more than 96% of the lunar surface will be shrouded.The event will end at 3:01 a.m.
ET when the moon exits the outer edge of Earth’s shadow.Most viewers in North and South America, except those in Alaska and the northernmost reaches of Canada, will have a chance to see every stage of the lunar eclipse.For those in Europe and Africa, however, the eclipse will begin early Friday, and the moon will set as the event is progressing.Unlike solar eclipses, lunar eclipses can be viewed safely with the naked eye, and skywatchers can use binoculars and telescopes to catch more dramatic views.The lunar eclipse follows a total solar eclipse — when the sun, the moon and Earth align, with the moon passing in front of the sun and blocking its light — that darkened skies in Spain, a small part of Portugal, Greenland, Iceland and nort...
