A camera aboard the Mars Reconnaissance Orbiter, called the High Resolution Imaging Experiment, or HiRISE, captured an image of the unusual geological feature in December.
The “nose” is actually a hill in the shape of the letter V; its “eyes” are two small, lopsided craters, according to the University of Arizona.
看似“熊的頭顱”的圓圈,被稱為“環(huán)形斷裂口”。研究人員表示,環(huán)形斷裂口可能是沉積物覆蓋撞擊坑后形成的。而“熊鼻子”可能是火山或泥漿噴口(volcanic or mud vent),沉積物可能是熔巖(lava)或泥漿(mudflows)。
The circle making up the “head” — what the university called “the circular fracture pattern” — “might be due to the settling of a deposit over a buried impact crater.”
It speculated: “Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?”
