A space observatory has detected X-rays coming from Pluto,
despite the fact that scientists believe that the dwarf planet is
incapable of producing high-energy photons.
The X-rays were detected
by NASA’s Chandra X-ray Observatory on four separate occasions as it
flew by Pluto between February 2014 and August 2015.
X-rays are
usually produced by the interaction of solar wind, the flow of charged
particles from the sun, and the neutral gas atoms around a planet or
comet.
