A later stage of freezing than frazil ice. It occurs when the crystals have coagulated to form a soupy layer on the surface. Grease ice reflects little light, giving the sea a matte appearance.

A hypothesized large concentration of mass (about 10^16 solar masses), some hundred million light-years from Earth, in the direction of the Centaurus supercluster, that seems to be affecting the moti
ons of many nearby galaxies by virtue of its gravity.
