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.....»»
How much of Venus"s atmosphere is coming from volcanoes?
There's a lot we don't know about the planet nearest to us. Venus is shrouded in clouds, making speculation about what's happening on its surface a parlor game for many planetary scientists for decades. But one idea that always seems to come up in th.....»»
A compact metasurface array-based system for single-shot spectroscopic ellipsometry measurement
Spectroscopic ellipsometry is widely adopted in semiconductor processing, such as in the manufacturing of integrated circuits, flat display panels, and solar cells. However, a conventional spectroscopic ellipsometer, as shown in Fig.1a, typically mod.....»»
ATLAS provides first measurement of the W-boson width at the LHC
The discovery of the Higgs boson in 2012 slotted in the final missing piece of the Standard Model puzzle. Yet, it left lingering questions. What lies beyond this framework? Where are the new phenomena that would solve the universe's remaining mysteri.....»»
HD 21997 is a high-frequency Delta Scuti pulsator, observations find
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have observed a young star designated HD 21997. Results of the new observations indicate that the studied object is a high-frequency Delta Scuti pulsator. The finding was describe.....»»
New spectrometer helps identify alternative catalyst materials for affordable hydrogen fuel cells
Fuel cells are quickly becoming a viable, clean energy alternative to commonly used fossil fuels, such as gasoline, coal, and oil. Fossil fuels are non-renewable energy resources that release carbon dioxide into the atmosphere......»»
Understanding the northward movement of the subtropical westerly jet in changing climates
The subtropical westerly jet is a high-altitude, fast-moving air current that flows from west to east in the subtropical region of the Earth's atmosphere. It's an important part of atmospheric circulation, influencing weather patterns and climate con.....»»
New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. The finding was published Ap.....»»
Finding new chemistry to capture double the carbon
Finding ways to capture, store, and use carbon dioxide (CO2) remains an urgent global problem. As temperatures continue to rise, keeping CO2 from entering the atmosphere can help limit warming where carbon-based fuels are still needed......»»
Atom interferometer charters Navy"s inertial navigation path to reduce drift
U.S. Naval Research Laboratory (NRL) researchers have developed a patent-pending Continuous 3D-Cooled Atom Beam Interferometer derived from a patented cold and continuous beam of atoms to explore atom-interferometry-based inertial measurement systems.....»»
CMS experiment at CERN measures a key parameter of the Standard Model
Last week, at the annual Rencontres de Moriond conference, the CMS collaboration presented a measurement of the effective leptonic electroweak mixing angle. The result is the most precise measurement performed at a hadron collider to date and is in g.....»»
The universe"s accelerated expansion might be slowing down
The universe is still expanding at an accelerating rate, but it may have slowed down recently compared to a few billion years ago, early results from the most precise measurement of its evolution yet suggested Thursday......»»
First indications of a rare, rainbow ‘glory effect’ on hellish exoplanet
Researchers believe they may have identified a set of rainbow-like colorful rings, called a glory, on a planet outside our solar system for the first time......»»
Heat-trapping carbon dioxide and methane levels in the air last year spiked to record highs again
The levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces, according to the U.S. National Oceanic and Atmospheric Administration......»»
ESA"s solar eclipse maker, Proba-3
Hundreds of millions of people will witness next week's total solar eclipse across North America, and solar physicists from around the globe are flocking to join them. Eclipses offer a brief glimpse of the sun's ghostly surrounding atmosphere—the s.....»»
Researchers envision sci-fi worlds involving changes to atmospheric water cycle
Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture......»»
Space scientists" new sensors shine spotlight on sun-Earth studies
Small, low-cost sensors developed by space scientists at The University of Texas at Dallas to study the Earth's upper atmosphere recently—and unexpectedly—provided information about the sun, something the devices were not designed to do......»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
Using one single image to realize on-orbit calibration of space camera lens distortion
In various space tasks such as space rendezvous-docking and on-orbit maintenance, the measurement of the relative posture and position of non-cooperative spacecraft is a key component. However, the commonly used global positioning system, radar detec.....»»
