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.....»»
New "Eclipse Watch" tool shows eclipses from space any time
Do you wish you could see a total solar eclipse every day? With a new online tool called Eclipse Watch, you can observe the sun's outer atmosphere, or corona, in real time with eclipse-like images from space as we count down to the next total solar e.....»»
Engineers "symphonize" cleaner ammonia production
Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the h.....»»
New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
Arecibo Observatory telescope outfitted with a wideband cryogenic system to expand its capabilities
Constructed within a natural sinkhole in Puerto Rico, the 305-meter-wide Arecibo Telescope played a part in numerous discoveries, including the first detection of an exoplanet. It was the largest radio telescope in the United States from 1963 until i.....»»
What do scientists hope to learn from total solar eclipse in US?
When a rare total solar eclipse sweeps across North America on April 8, scientists will be able to gather invaluable data on everything from the sun's atmosphere to strange animal behaviors—and even possible effects on humans......»»
New computational technique enhances accuracy of measurements in nuclear geoscience
Conventional nuclear measurement techniques, such as Monte Carlo simulations, are known for their extensive computational demands and prolonged processing times, especially when applied to unconventional reservoirs characterized by complex lithologie.....»»
New study reveals influencers of global biogenic volatile organic compound emission trends over the last 20 years
Biogenic volatile organic compounds (BVOCs) emitted by vegetation are important precursors of ozone and secondary organic aerosols in the atmosphere, affecting air quality, clouds, and climate. However, BVOC emissions remain highly uncertain because.....»»
New nearby mini-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new mini-Neptune exoplanet orbiting a nearby star. The newfound alien world, designated TOI-4438 b is about 2.5 times larger than the Earth. The finding was detailed in a paper published.....»»
Estimating coastal water depth from space via satellite-derived bathymetry
Since ancient times, knowing the depth of coastal waters has been key to safe and successful navigation and to exploit the sea's resources. Today, bathymetry—the measurement of sea depth—is even more important, playing essential roles in our unde.....»»
Scientists detail research to assess the viability and risks of marine cloud brightening
As the levels of greenhouse gases in the atmosphere continue to increase and climate change impacts become more costly, the scientific community is redoubling efforts to investigate the potential risks and benefits of artificially shading Earth's sur.....»»
Webb finds hints of a third planet at PDS 70
The exoplanet census now stands at 5,599 confirmed discoveries in 4,163 star systems, with another 10,157 candidates awaiting confirmation. So far, the vast majority of these have been detected using indirect methods, including transit photometry (74.....»»
Livestock farming is responsible for up to a quarter of air pollution in Lombardy region: Study
Agricultural activities and livestock farming are key contributors to the concentrations of hazardous pollutants for health and the environment in the atmosphere, but the potential action in these sectors is often overlooked in public debate......»»
Eyes on the impossible: First near-field, subwavelength thermal radiation measurement
Nanodevices change the way we diagnose disease, process food and water, and store renewable energy. But to keep up with next-generation technology, researchers need to understand the fundamental principles that prompt their functionality......»»
Searching for the decay of nature"s rarest isotope: Tantalum-180m
Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei's protons or neutrons.....»»
Could Earth life survive on a red dwarf planet?
Even though exoplanet science has advanced significantly in the last decade or two, we're still in an unfortunate situation. Scientists can only make educated guesses about which exoplanets may be habitable. Even the closest exoplanet is four light-y.....»»
Climate: Carbon capture tech is booming, and confusing
Humanity's failure to reduce planet-heating carbon pollution—at record levels in 2023—has thrust once-marginal options for capping or reducing CO2 in the atmosphere to center stage......»»
Watch SpaceX’s Starship burn brightly as it hurtles toward Earth
Dramatic footage shows SpaceX's Starship spacecraft lighting up as it reentered Earth's atmosphere following a successful test flight on Thursday morning......»»
SpaceX mega rocket lost in final phase of test flight
Starship, the world's most powerful rocket, flew further and faster than ever before during its third test flight Thursday, although it was eventually lost as it re-entered the atmosphere over the Indian Ocean, SpaceX said......»»
Jailbreaking an iPhone re-enables blood oxygen measurement on Apple Watch; August 2028 expiry
An interesting look behind the scenes of the court battle between Apple and health tech company Masimo reveals that jailbreaking an iPhone re-enables blood oxygen measurement on an Apple Watch. The same report notes that even if Apple doesn’t su.....»»
AI analysis of satellite images shows 1990s USSR collapse increased methane emissions, despite lower oil, gas production
