NGC 4151
A false-color image of the nuclear region of the galaxy NGC 4151, showing a region about 1000 light-years across. Blue is radio emission, green is optical emission from ionized oxygen as seen with the Hubble Space Telescope, and red is X-ray emission as seen by the Chandra X-ray Observatory. The X-ray data represent the first such fine-scale X-ray imaging of an extreme galaxy nucleus.
