In fact, it is thanks to Hubble's Wide Field Camera 3 (WFC3) that we are able to see Liller 1 so clearly in this image, because the WFC3 is sensitive to wavelengths of light that the human eye can't detect. Liller 1 is only 30,000 light-years from Earth--relatively neighborly in astronomical terms--but it lies within the Milky Way's "bulge," the dense and dust...
