NASA releases stunning new pic of Milky Way's 'downtown'
NASA has released a stunning new picture of our galaxy's violent, super-energized "downtown."
It's a composite of 370 observations over the past two decades by the orbiting Chandra X-ray Observatory, depicting billions of stars and countless black holes in the center, or heart, of the Milky Way. A radio telescope in South Africa also contributed to the image, for contrast.
