The Orion nebula is about 1350 light years from Earth. This infrared image, taken by VISTA, shows young stars deep in the nebula, which are obscured by dust when observed with visible light.
This image, a composite of 10-minute exposures taken at different wavelengths in the near-infrared part of the spectrum, covers a region of sky about 1 by 1.5 degrees.
