Big stellar cluster in the blue dwarf galaxy NGC 5253

Composite colour-coded image of the small starburst galaxy NGC 5253, at a distance of 11 million light-years. It is based on one near-infrared image (in the K-band at wavelength 2.16 μm; here coded red) obtained with the ESO Very Large Telescope (VLT) and two images in the visual spectral region (V- (0.55 μm) and I-bands (0.79 μm), here blue and green, respectively) with the NASA/ESA Hubble Space Telescope (HST). The image covers 80 x 80 square arcseconds on the sky. North is up and East is to the left.
