Logo SpaceweatherThis is a composite image of exploding Comet 17P/Holmes. German astrophotographer Sebastian Voltmer combined various exposures taken through his 4.1-inch refracting telescope and processed the composite to highlight the comet's bright golden core (with jets and streamers), its gossamer green halo and an emerging faint blue tail. It's one of the strangest and most beautiful photos of a comet ... ever.
