According to the Messenger findings, carbon dioxide gas makes up over 95 percent of Mercury’s atmosphere. Although on Earth, carbon dioxide is strongly associated with life, it is very unlikely that Mercury’s
Arctic mercury (Hg) concentrations respond to changes in anthropogenic Hg emissions and environmental change. This manuscript, prepared for the 2021 Arctic Monitoring and Assessment Programme Mercury Assessment, explores the response of Arctic Ocean Hg concentrations to changing primary Hg emissions and to...
The smallest planet in the solar system, Mercury bears a strong resemblance to Earth's moon. Like the other three terrestrial planet, Mercury contains a core surrounded by a mantle and a crust. But Mercury's core makes up a larger portion of the planet than others in the solar system, hi...
Exposure is almost always via fish that have been contaminated with methylmercury -- a form of mercury produced in the bodies of tiny sea life that have ingested the elemental form, deposited in bodies of water when rain or snow carry it down from the atmosphere or across land in ...
What layer of the atmosphere is the magnetosphere in? What is the closest planet to Neptune? Which gases made up most of Earth's early atmosphere? What is Rigel made of? What makes Neptune unique? Is Neptune the coldest planet? Why are planets beyond Neptune not gas planets? Which of the...
Mercury has almost no atmosphere, partly because its gravity is so low that it can't keep gases close to its surface. In addition, the planet is so close to the sun that the solar wind blows away any gases that accumulate near the surface. The trace atmosphere of the planet includes sma...
Such an increase in solar energy will introduce Earth to a whole new kind of global warming. The polar ice caps will melt and the atmosphere will fill with water vapor that traps even more heat. By one or two billion years from now, temperatures will have risen so much that the oceans ...
VHS 1256b is actually closer to a brown dwarf than a planet. Its huge, but it isn’t big enough to start fusion and become a star. The silicate clouds in the atmosphere might actually be a type of sand. One of the reasons VHS 1256b could be observed so well is that, unlike many...
