And the winner is...

Back in August I mentioned that the US's National Radio Astronomy Observatory (NRAO) was having another competition to find nice images made by the radio telescopes and interferometers that they operate. I've just seen (via Universe Today who, incidentally, mistakenly describe it as a photograph which it certainly isn't) that the winners have been announced. The winning image was created by combining data taken by the Greenbank radio telescope, the Very Large Array in New Mexico and the Midcourse Space Experiment satellite. It shows a huge - we're talking 1000 lightyears across - interstellar bubble that was probably created by the wind from a few hot, massive stars. As this is actually radio emission we are observing, the colours are not the true colours but are chosen to give you an idea of the different chemicals in the image. Read the full press release for more. I must admit, my eye was more slightly more taken by the zoo of galaxies that took second place.
