the Eagle nebula, an industrious star-making factory located 7,000 light-years away in the Serpens constellation. The image shows the region's entire network of turbulent clouds and newborn stars in infrared light. The color green denotes cooler towers and fields of dust. Since light from the Eagle nebula takes 7,000 years to reach us, this 'supernova' explosion would have appeared as an oddly bright star in our skies about 1,000 to 2,000 years ago.
I've always found it intriguing to know that the further away we look into space, the further back we're looking into time. We are literally looking into the past! ;)
