Shown here are higher-energy X-ray objects in or near our galaxy. The sources are largely stellar-mass black holes, neutron stars, pulsars and supernova remnants. The colors depict X-ray energy in which red is lower energy and blue is the highest; white is an even mix of lower-energy and higher-energy X-ray photons. These sources are not included in the Swift survey because they are too distant for the satellite to image. Credit: NASA/Swift/BAT/Markwardt et al.
