Astronomers and space enthusiasts are in for a treat this weekend, as a rare green comet is due to make a fly-by past Earth at the same time as a rare eclipse.
The comet, known as 45P/Honda-Mrkos-Pajdušáková, glows bright green, with the heat from the sun making it ooze a purple tail.
However, it's not the only rare cosmic event to take place over the weekend.
Late on Friday evening, an event known as a penumbral lunar eclipse will occur. This happens when the earth, sun and moon line up, and will have the effect of creating the 'snow moon' - a moon which is more bright and luminous than usual.
The eclipse and comet will be best seen in Europe or Africa.
