NASA finds 'butterfly' in space



Stunning images courtesy of NASA's Spitzer Space Telescope have revealed a 'butterfly' shaped nebula 1,400 light-years from the Sun. Officially known as W40, this red butterfly in space is a nebula, or a giant cloud of gas and dust. The 'wings' of the butterfly are giant bubbles of gas being blown from the inside out by massive stars.
