Webb identifies methane in an exoplanet"s atmosphere
The James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a doz.....»»
Tidal wetlands study offers improved predictions of methane gas emissions
An international study led by UAB researcher Ariane Arias-Ortiz, and published in Global Change Biology, has analyzed methane gas fluxes in more than 100 tidal wetlands and marshes in the U.S......»»
More water worlds than we thought might support life
Too much water on exoplanet surfaces would mean high pressure ices, not life. Enlarge / High pressure ices near the crust are a feature of water-rich worlds.` (credit: Benoit Gougeon (University of Montreal)) The possibi.....»»
Astronomers discover iron winds on an ultra-hot exoplanet
An international team of astronomers, including scientists from the University of Geneva (UNIGE) and the PlanetS National Center of Competence in Research, has identified the presence of iron winds in the atmosphere of the ultra-hot Jupiter WASP-76 b.....»»
A space oddity—small exoplanet challenges existing theories on planet formation
A research team led by Lund University in Sweden has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more complex than researc.....»»

The 15 top methane-emitting nations lack policies to rein them in
While the United States and China have taken important steps to reduce their methane emissions, other significant producers of the potent greenhouse gas rarely have concrete national plans to mitigate it, according to a new University of Maryland ana.....»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
Sulfurous acid detected in gas phase under atmospheric conditions for first time
Once again, the atmosphere amazes us with its diverse chemical processes. For the first time, researchers at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig have demonstrated the existence of sulfurous acid (H2SO3) under atmospher.....»»
How vegetation could impact the climate of exoplanets
The term "habitable zone" is a broad definition that serves a purpose in our age of exoplanet discovery. But the more we learn about exoplanets, the more we need a more nuanced definition of habitable......»»
Webb discovers six new "rogue worlds" that provide clues to star formation
Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out......»»
The impact of human activity on air quality: A look at aerosol pollution before and after the Industrial Revolution
A recent study led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences sheds new light on how human activities have altered the composition of the atmosphere over time, particularly focusing on secondary organic aerosols (SOA)......»»
James Webb is explaining the puzzle of some of the earliest galaxies
Webb has been causing bafflement in the field of cosmology. But the problem isn't that the universe is broken - it's that early black holes were playing tricks......»»
Climate change feedbacks lead to surge in natural methane emissions
Attempts to cut greenhouse gases made tougher by increased emissions. Enlarge / A view of the Pantanal wetlands in Brazil. New research shows a large chunk of global methane emissions are from rotting vegetation in tropical wetla.....»»
In six new rogue worlds, Webb Telescope finds more star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it......»»
US grid adds batteries at 10x the rate of natural gas in first half of 2024
By year's end, 96 percent of the US's grid additions won't add carbon to the atmosphere. (credit: DOE) While solar power is growing at an extremely rapid clip, in absolute terms, the use of natural gas for electricity pr.....»»
Study identifies keys to success of evidence-based decision making
Evidence-based decision making (EBDM)—using the best available evidence from multiple sources to make informed decisions—is critical to the success of any organization. In a new study, researchers have explored what makes EBDM work. They found th.....»»
Researchers propose inexpensive 2.2-kilometer telescope that could make exoplanet movies
Can a kilometer-scale telescope help conduct more efficient science, and specifically for the field of optical interferometry? This is what a study recently posted to the preprint server arXiv hopes to address......»»
