... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

. This artist s impression shows how photons in the cosmic microwave background (CMB) are deflected by the gravitational lensing effect of massive cosmic structures as they travel across the universe. Gravitational lensing creates tiny, additional distortions to the mottled pattern of the CMB temperature fluctuations. A small fraction of the CMB is polarized; one component of this polarized light, B-modes, have been given an additional signature by gravitational lensing. ESA/Planck Collaboration
