Astronomers do come up with imaginative names, the latest being Cloverleaf Quasar (a.k.a. H1413+117). I guess at a push the image produced by the Chandra telescope looks sort of cloverleaf shaped (see below).

I am not very convinced by this name, well I guess you have to come up with something and heck it is still a very cool image, especially when you think why it is being caused. For more see: http://chandra.harvard.edu/photo/2004/h1413/
