The earliest atmosphere on Mercury
Mercury is a most unusual planet. The smallest planet in the solar system, and the closest planet to the sun, it is in a 3:2 spin resonance, slowly turning and experiencing scorching heat up to 430 degrees Celsius, and the night side frigid, down to.....»»
NASA"s compact infrared cameras enable new science
A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth's upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets......»»
A review of the applications of mercury stable isotopes for tracing volcanism in geologic events
Mercury is a toxic heavy metal that can exist stably as a gas, with high volatility and global distribution in the atmosphere. Volcanoes represent a primary natural source of Hg in the atmosphere, with significant effects on Hg cycles on both global.....»»
Researchers investigate mercury concentrations in fish and wildlife on a global scale
A paper, titled "Global Mercury Concentrations in Biota: Their Use as a Basis for a Global Biomonitoring Framework" and published in the journal Ecotoxicology, describes for the first time currently available mercury data for fish and wildlife on a g.....»»
Why Earthlings are safe when huge solar storms strike our planet
When solar storms and coronal mass ejections hit Earth and create the Northern Lights, people are physically protected from radiation by Earth's magnetic field and atmosphere. From time to time, the sun discharges billions of tons of solar matt.....»»
Mission control is trying "restlessly" to save a spacecraft to Mercury
A joint European and Japanese spacecraft bound for Mercury has encountered thrust problems that could jeopardize the future of the mission. A complex mission to Mercury that began its epic space voyage six years ago has encountered critical thr.....»»

Health systems eliminating a form of anesthesia that hangs in the air for more than a decade after use
Philadelphia-area health systems are phasing out a common anesthesia gas that hangs in the atmosphere for 14 years. Desflurane is the most potent greenhouse gas found in hospitals, which are increasingly engaged in efforts to reduce their carbon foot.....»»
Discovery of the first ancestors of scorpions, spiders and horseshoe crabs
Who were the earliest ancestors of scorpions, spiders and horseshoe crabs? A Ph.D. student from the University of Lausanne (Switzerland), with the support of a CNRS researcher, has identified a fossil that fills the gap between modern species and tho.....»»

NASA’s Quest to Touch the Sun
The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. NASA sent a probe to find out why—by getting closer to the star than ever before......»»
Study finds consistent decline in nitrogen oxides emissions from human activities in China since 2020
Nitrogen oxides (NOx) form aerosols and ozone in the atmosphere and are significant contributors to air pollution and climate change. China is the largest emitter, yet accurate and timely information on NOx emissions in China has been lacking since 2.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
James Webb telescope peers at the atmosphere of a rocky hell world
