This very colorful field of view contains an extremely famous object: a supernova remnant known as the Jellyfish Nebula, found approximately 5,000 light-years from Earth in the Gemini Constellation. Ultimately, the remnant is a small part of a much larger whole—called IC 443.

Based on a number of factors, astronomers estimate that the explosion that proceeded the formation of the remnant happened around 35,000 years ago–with the light traversing the intervening space, and arriving on Earth 30,000 years back (when the Neanderthals went extinct).

This image of the Jellyfish nebula was taken using NASA’s Wide-field Infrared Survey Explorer (more commonly known as WISE). NASA examines the region, points out objects of interest, and explains what the colors mean (See a larger image here):
