This composite image shows the Tarantula Nebula. The background image, taken in the infrared, is itself a composite: it was captured by the HAWK-I instrument on ESO’s Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA), shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks that have been superimposed on the image come from radio observations taken by the ALMA, revealing regions of cold, dense gas which have the potential to collapse and form stars. The unique web-like structure of the gas clouds led astronomers to the nebula’s spidery nickname. Image credit: ESO / ALMA / NAOJ / NRAO / Wong et al. / M.-R. Cioni / VISTA Magellanic Cloud Survey / Cambridge Astronomical Survey Unit.
