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.....»»
A Jupiter-sized planet has been hiding a big secret: A 350,000-mile-long tail
WASP-69b is having a hot girl summer that never ends. The huge gaseous exoplanet, roughly the size of Jupiter and approximately 160 light years from Earth, orbits its searing host star so closely that its atmosphere is boiling away at a rate of 200,0.....»»
Secrets of a hot Saturn and its spotted star unlocked
A team of astronomers including McGill Professor Nicolas Cowan has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star's activity.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar d.....»»
Seeking another Earth? Look for low carbon dioxide
In our own Solar System, Earth has far lower CO2 concentrations than its neighbors. Enlarge (credit: NASA/JPL/Caltech) What do we need to find if we want to discover another Earth? If an exoplanet is too far away for eve.....»»
The importance of corporate climate disclosure and measuring financial costs of environmental impacts
Under the Biden administration, there has been an effort to do a better job of measuring public and private environmental impacts. The federal government is trying to develop ways of improving the measurement of environmental costs and benefits of pu.....»»
Increase in rice farming in sub-Saharan Africa found to be producing rising amounts of methane
A team of engineers and atmospheric scientists at Harvard University, working with a colleague from the California Institute of Technology's Jet Propulsion Laboratory, has calculated the increased amount of methane being expelled into the atmosphere.....»»
Mysterious missing component in the clouds of Venus revealed
What are the clouds of Venus made of? Scientists know it's mainly made of sulfuric acid droplets, with some water, chlorine, and iron. Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been un.....»»
See the weather patterns on a wild, super hot exoplanet
Planet WASP-121 b has a surface temperature of 5,000 degrees Fahrenheit, which researchers predict would lead to some wild weather phenomena......»»
New theoretical framework unlocks mysteries of synchronization in turbulent dynamics
Weather forecasting is important for various sectors, including agriculture, military operations, and aviation, as well as for predicting natural disasters like tornados and cyclones. It relies on predicting the movement of air in the atmosphere, whi.....»»
Iron snow ebb and flow may cause magnetic fields to come and go
Just as snow crystals form in the upper atmosphere, then fall to lower, warmer elevations and melt, scientists believe a phenomenon called iron snow happens in the molten iron cores of some planetary bodies. Cooling near the core-mantle boundary crea.....»»
Quantum thermal transistors: Harnessing quantum measurement and feedback
Researchers are actively engaged in the dynamic manipulation of quantum systems and materials to realize significant energy management and conservation breakthroughs......»»
TRAPPIST-1c isn"t the exo-Venus we were hoping for, but don"t blame the star
A recent study posted to the arXiv preprint server and accepted to The Astrophysical Journal uses computer models to investigate why the exoplanet, TRAPPIST-1c, could not possess a thick carbon dioxide (CO2) atmosphere despite it receiving the same a.....»»
Novel toxic gas sensor improves the limit of nitrogen dioxide detection
Researchers at the Korea Research Institute of Standards and Science developed a toxic gas sensor with the world's highest sensitivity. This sensor can precisely monitor nitrogen dioxide (NO2), a toxic gas in the atmosphere, at room temperature with.....»»
A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets, study finds
Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers' best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical feature in their atmospheres.....»»
The atmosphere of an exoplanet reveals secrets about its surface
As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface of a planet from view. A.....»»
Light measurement enables estimation of the chemical attributes of spice extracts
Spices and other plant-derived products contain many active components, such as polyphenols and flavonoids. However, even the slightest variations in conditions can considerably affect the extraction efficiency of these active components, posing chal.....»»
World"s first coffee bean Certified Reference Material for component analysis
The Korea Research Institute of Standards and Science (KRISS) has developed the world's first Certified Reference Material (CRM) capable of accurate measurement of the nutritional and harmful elements in coffee beans......»»
Ordering of neutrino masses may be revealed by measuring those produced in Earth"s atmosphere
A group of physicists, three with Harvard University's Department of Physics and Laboratory for Particle Physics and Cosmology, and the fourth with the University of Liverpool, has found evidence suggesting that additional measurements of neutrinos g.....»»
Researchers argue back and forth about whether we’ve spotted an exomoon
