Update for 11:15 a.m. on April 18: We are just one day away from witnessing a rare hybrid solar eclipse! Weather forecasts look great for Perth, Australia, one of the locations that will be able to witness the spectacle. We've updated our livestream options below for skywatchers interested in seeing the event who aren't in the path of this rare eclipse. The eclipse will begin at 9:36 p.m. EDT on April 19 (0136 GMT on April 20). Let's hope for clear skies!
A rare celestial event is happening this week.
On Thursday (April 20), the moon will block out the sun during what is known as a hybrid solar eclipse. This type of eclipse shifts from total solar eclipse to annular (ring-shaped) as the moon's shadow moves across the surface of the Earth. The last hybrid solar eclipse happened in 2013, and the next will occur in 2031. After that, future skywatchers will have to wait until March 23, 2164.
The event will be visible from the South Pacific, with the moon's shadow passing over western Australia, East Timor and Indonesia beginning at 9:36 p.m. EDT on April 19 (0136 GMT on April 20) and ending at 2:59 a.m. EDT (0659 GMT) the next day, according to In the Sky (opens in new tab).
If the path of the eclipse doesn't pass over your location, you're still in luck: There will be multiple free livestreams bringing the celestial action right to the screen of your choice.
