False-color image of an all-sky HI (neutral hydrogen) survey. The bright band across the center represents the plane of our Milky Way galaxy, showing vast clouds of hydrogen gas tens to hundreds of light-years across. These structures are shaped by stellar activity within the galactic disk. The image is based on radio wave emissions from hydrogen atoms at a wavelength of 21 centimeters.

ROSAT's all-sky X-ray image reveals the Milky Way Galaxy's plane (horizontally), showcasing bright X-ray sources like the Vela Pulsar and Puppis supernova remnant. Extragalactic objects such as the Virgo Cluster and the Large Magellanic Cloud are also visible. Dark bands represent X-ray absorption by galactic gas and dust. The image uses color to represent different X-ray energy ranges.
