Geology of Mercury

The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term geo...

APOD_20130612_All of Mercury_수성 표면 전체의 모습

Previously, much of the Mercury's surface was unknown as it is too far for Earth-bound telescopes to see clearly, while the Mariner 10 flybys in the 1970s observed only about half. The above video is a compilation of...

Mercury: Facts

Introduction Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to r...

Mercury may have a layer of diamond beneath its grey surface

When the planet Mercury formed 4 billion years ago, conditions may have been just right to form a thick layer of diamonds below its surface

What is Mercury Made Of? | Space

Mercury is a terrestrial planet with a rocky surface and metallic core.

Mercury's Poles May Be Icier Than Previously Thought

The scorching hot surface of Mercury seems like an unlikely place to find ice, but research over the past three decades has suggested that water is frozen on the first rock from the Sun, hidden awa…

Less than one weight percent of graphite on the surface of Mercury | Nature Astr

The surface of Mercury is enriched in carbon compared with the other terrestrial bodies. Up to 4 wt% of carbon in the form of graphite has been invoked to explain its mysteriously low surface refle...
