Best known as a swan winging its way across the night, the constellation Cygnus is easily seen in the northern hemisphere's summertime sky. This new view of the Cygnus-X star-forming region by the Herschel Telescope highlights chaotic networks of dust and gas that point to sites of massive star formation.
The butterfly starts life as a caterpillar, which cocoons itself in a silky thread. The caterpillar emerges from it's time in the pod, with colourful wings. The butterflies in the tropical rain forests of the southern hemisphere, can get to incredible sizes, with the wings of these butterflies displaying some of the brightest colours in the natural world.
