At the end of May 2013, Jupiter, Venus and Mercury form a celestial triangle in the night sky.
The three planets shine together in a triangle formation low in the western sky in a planetary meet-up known as a conjunction.
We can even see them with naked eyes if the sky is clear and the place is not too bright.
This cosmic show is so special spectacular because it includes the three brightest planets visible in the May night sky.
Venus is the brightest of the trio, with Jupiter a close second and Mercury coming in third.
Flickr photographers snapped awesome photos of this very rare and special event.
