This colour image of the region known as NGC 2264 — an area of sky that
includes the sparkling blue baubles of the Christmas Tree star cluster and the
Cone Nebula — was created from data taken through four different filters (B, V,
R and H-alpha) with the Wide Field Imager at ESO’s La Silla Observatory, 2400 m
high in the Atacama Desert of Chile in the foothills of the Andes. The image
shows a region of space about 30 light-years across.
