Cosmic Hand Reaches for the LightCredit: NASA. Red represents low-energy X-rays, the medium range is green, and the most energetic ones are colored blue. The blue hand-like structure was created by energy emanating from the nebula around they dying star PSR B1509-58. The red areas are from a neighboring gas cloud called RCW 89.
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 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. Credit: ESO
