Comet 67P stunning photo of sublimating ice jets?

Comet 67p - sublimated ice jets waterThis stunning picture of comet 67P (active asteroid 67P) shows either lots of jets streaming from its surface or is evidence of an Electric Universe.

How can frozen water in the depths and cold of space be converting straight from ice to gas (sublimation) when buried beneath the surface and so far away from the Sun?

Could the jets be the electrical interaction of the charged asteroid and the Suns solar wind (charged plasma?).
