About this Image
XMM-Newton image of Geminga (up) showing the discovery of twin tails. The motion of Geminga across the sky is indicated, showing the trailing tails of the neutron star. The scale bar corresponds to a distance of 1.5 million million kilometres at the distance of Geminga.
EPIC-pn spectrum (below) of Geminga. The data points (black) are shown together with the three components spectrum: a power-law (blue), a cool black-body (green) and a hot black-body (red). The black-body component would originate on a ~60-meter-radius rotating hot spot on the pulsar's surface.
Investigator(s): Caraveo, P. A.; De Luca, A.; Mereghetti, et al.
