Tuesday will mark the last time a total lunar eclipse will light up the night sky...at least for three years.
Tomorrow's eclipse will be seen in North America during predawn hours beginning around midnight and enter totality at around 2am.
The total lunar eclipse, also known as a blood moon, will give off a reddish orange tint.
Though it'll be a while before the next total lunar eclipse, NASA says there will be several partial lunar eclipses before then.
