Colour Composite of W49A

Composite near-infrared colour image from NTT/SofI of the Giant Molecular Cloud W49A. It covers a sky area of 5 x 5 arcmin 2 and the red, green and blue colours correspond to the Ks- (wavelength 2.2 µm), H- (1.65 µm) and J-band (1.2 µm), respectively. North is up and East is to the left. The labels identify known radio sources. The main cluster is seen north-east of the region labelled "O3". The colour of a star in this image is mostly a measure of the amount of dust absorption towards this star. Hence, all blue stars in this image are located in front of the star-forming region.
