Stargazers are in for a treat tomorrow, as a rare 'hybrid' lunar eclipse is set to plunge parts of the world into total darkness.
This type of astronomical event - where the moon blocks out a different proportion of the sun in different parts of the world - only occurs once every 10 years.
In some places, viewers will experience a 'total' solar eclipse, where the face of the sun is completely blocked by the moon.
But in others, an 'annular' solar eclipse will be visible, where the moon appears slightly smaller than the sun, leaving a ring of light around its silhouette.
According to Royal Observatory Greenwich, the event will only be visible from parts of the equator and southern hemisphere, and not from the UK or the US.
But for those in other parts of the world who want to witness the total solar eclipse, NASA is putting on a livestream from Perth Observatory in Western Australia.
This will start at 03:30 BST on Thursday morning (22:20 EDT on Wednesday night), and viewers will have the chance to ask NASA scientists questions about the phenomenon.
The last time a hybrid solar eclipse occurred was way back in November 2013, plunging parts of Africa, Europe and America into darkness.
And keen astronomers certainly won't want to miss this week's event, as the next one isn't due until November 2031.
