Small white butterfly egg | Jo Angell Design
Coloured scanning electron micrograph (SEM) of an egg of the small white butterfly (Pieris rapae). Eggs are laid singly on the underside of leaves of Brassica plants (cabbage, broccoli) and nasturtiums. The sculpted shell is made of a protein called chorionin and has central aeropyles, breathing pores (brown), that allow air to flow to the developing embryo. Magnification: x160 when printed at 10 centimetres tall.

In March 2003, Saturn’s rings were at maximum tilt toward Earth, a special event occurring every 15 years. With the rings fully tilted, astronomers get the best views of the planet’s Southern Hemisphere. They took advantage of the rings’ unique alignment by using Hubble to capture some stunning images.
