Atmosphere of the Planet MercuryI NOTICE, in the Supplement to NATURE of February 9, that the existence of an atmosphere on the planet Mercury has again been pronounced impossible on account of the small mass of the planet.doi:10.1038/135549a0ANTONIADIE. M.NatureNature...
Mercury - Atmosphere, Temperature, Radiation: A planet as small and as hot as Mercury has no possibility of retaining a significant atmosphere, if it ever had one. To be sure, Mercury’s surface pressure is less than one-trillionth that of Earth. Neverth
Peatland vegetation takes up mercury (Hg) from the atmosphere, typically contributing to net production and export of neurotoxic methyl-Hg to downstream ecosystems. Chemical reduction processes can slow down methyl-Hg production by releasing Hg from peat back to the atmosphere. The extent of these p...
Atmospheric gaseous elemental mercury (GEM) concentrations in the Arctic exhibit a clear summertime maximum, while the origin of this peak is still a matter of debate in the community. Based on summertime observations during the Multidisciplinary driftin
The modern English name "mercury" comes from the planet Mercury. In medieval alchemy, the seven known metals—quicksilver, gold, silver, copper, iron, lead, and tin—were associated with the seven planets. Quicksilver was associated with the fastest planet, which had been named after the Roman...

The extent to which humans have polluted environmental reservoirs over centuries or millennia is often expressed in terms of enrichment factors. Natural archives such as lake and peat sediments and ice cores have been used to estimate Hg enrichment in deposition, and by inference in the atmosphere....
(Scientists later determined that the giant planet has more than six moons,)But what lay beneath those colorful clouds? Was there a solid surface? Or did Jupiter’s atmosphere blend i 一样从前,象1610年伽利略观察木星有四非常大月亮,其中之一几乎是行星水星的大小。 (科学家后确定大行星有超过六月亮...
Mercury, the innermost planet of the solar system and the eighth in size and mass. Its closeness to the Sun and its smallness make it the most elusive of the planets visible to the unaided eye. Because its rising or setting is always within about two hou
Mercury was named by the Romans after the fleet-footed messenger of the gods because it seemed to move more quickly than any other planet.
