Data at Wavelength of 0.45 mm (IMAGE) Royal Astronomical Society Caption Data at wavelength of 0.45 mm, combined from SCUBA and SCUBA-2, in a false-color image. The Geminga pulsar (inside the black circle) is moving towards the upper left, and the orange dashed arc and cylinder show the 'bow-wave' and a 'wake.' The region shown is 1.3 light-years across; the bow-wave probably stretches further behind Geminga, but SCUBA imaged only the 0.4 light-years in the center.
