Earlier this week, John West of Arizona State University and his colleagues found evidence of a large cylindrical blob of cold material far below the surface of central Nevada.

"Honey dripping off of a spoon is a visual aid to what we think the drip looks like," West told LiveScience. "Dripping honey tends to lead with a large blob of honey, with a long tail of material following the initial blob."

He said the blob is between about 30 miles and 60 miles in diameter and extends from a depth of about 47 miles to at least 310 miles beneath Earth's surface.

Last year, Arizona State University Allen McNamara explained how Earth is not neatly divided into a crust, mantle and core. Rather, several large blobs of highly compressed rock — which he described as behaving like honey or peanut butter — exist.
