  We have used the Coronagraphic and Heliospheric Imaging data from Solar
TErrestrial RElations Observatory (STEREO) to observe a prominence which is
erupted on June 7th, 2011. This prominence is subjected to the morphological
evolution of MRT instability from the lower solar corona upto the
inter-planetary space. The unstable structures are converted into the bunch of
localized plasma spikes due to the turbulent mixing, and propagate in the
inter-planetary space upto 1 A.U.
