First measurement of isotopes in atmosphere of exoplanet
An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b at a distance of 300 light years in the c.....»»
Scientists use carbon isotopes to track "forever chemicals"
Organofluorine compounds—sometimes called "forever chemicals"—are increasingly turning up in our drinking water, oceans and even human blood, posing a potential threat to the environment and human health......»»
How efficiently different US forests will remove atmospheric carbon in the future
Forests absorb carbon by capturing carbon dioxide from the atmosphere, making forest carbon stocks an important resource against climate change. In research published in Ecology and Evolution, investigators examined existing tree regeneration pattern.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Gulf of Mexico "dead zone" larger than average, scientists find
NOAA-supported scientists have announced that this year's Gulf of Mexico "dead zone"—an area of low to no oxygen that can kill fish and marine life—is approximately 6,705 square miles, the 12th largest zone on record in 38 years of measurement. T.....»»
Scientists find a human "fingerprint" in the upper troposphere"s increasing ozone
Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant.....»»
Medieval French diets discovered through isotope analysis reveal social and religious influences
Archaeologists working in the Languedoc region in southern France have used stable isotopes to reveal new insights into medieval dietary practices. The research, published in Archaeological and Anthropological Sciences by lead author Dr. Jane Holmstr.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
TIC 441725813 is a hybrid pulsating subdwarf star, study finds
Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe a subdwarf star designated TIC 441725813. In result, they found that TIC 441725813 is a hybrid hot B subdwarf pulsator. The discovery was detailed in a research.....»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
The discovery of a new Earth-like planet could shed further light on what makes a planet habitable
In an exciting breakthrough for astronomy and the search for extraterrestrial life, a team of international scientists has announced the discovery of Gliese 12 b, a temperate, Earth-sized exoplanet just 40 light-years away—a relatively neighborly 3.....»»
The New Gods of Weather Can Make Rain on Demand—or So They Want You to Believe
In a gold-trimmed command center on the outskirts of Abu Dhabi, scientists are seeking to wring moisture from desert skies. But will all their extravagant cloud-seeding tech—planes that sprinkle nanomaterials, lasers that scramble the atmosphere—.....»»
Scientists untangle interactions between the Earth"s early life forms and the environment over 500 million years
The atmosphere, the ocean and life on Earth have interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article on this c.....»»
Webb directly images giant exoplanet that isn’t where it should be
Six times bigger than Jupiter, the planet is the oldest and coldest yet imaged. Enlarge / Image of Epsilon Indi A at two wavelengths, with the position of its host star indicated by an asterisk. (credit: T. Müller (MPIA/HdA), E......»»
Trees reveal climate surprise: Microbes living in bark remove methane from the atmosphere
Tree bark surfaces play an important role in removing methane gas from the atmosphere, according to a study published 24 July in Nature......»»
Webb images nearest super-Jupiter, opening a new window to exoplanet research
Using the James Webb Space Telescope (JWST), an MPIA-led team of astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius a.....»»
New research proposes better carbon storage with stacked geology
The overarching goal of all carbon capture and storage projects is the same: Keep carbon dioxide (CO2) emissions out of the atmosphere by storing them in the subsurface for good......»»
Carbon dating: Developing a measurement tool for a 23-year-old cold case
When local law enforcement are unable to identify skeletal remains, they may seek out external resources and capabilities like those at Lawrence Livermore National Laboratory's (LLNL) Center for Accelerator Mass Spectrometry (CAMS). That's exactly wh.....»»
