How astronomers used James Webb to detect methane in the atmosphere of an exoplanet
Scientists using the James Webb Space Telescope recently announced they had made a rare detection of methane in an exoplanet atmosphere......»»
Airborne microplastics aid in cloud formation
It turns out microplastics have an effect on the weather and climate. Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such.....»»
AWS security essentials for managing compliance, data protection, and threat detection
AWS offers a comprehensive suite of security tools to help organizations manage compliance, protect sensitive data, and detect threats within their environments. From AWS Security Hub and Amazon GuardDuty to Amazon Macie and AWS Config, each tool is.....»»
Nearly three years since launch, Webb is a hit among astronomers
Demand for observing time on Webb outpaces supply by a factor of nine. From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther.....»»
New PFAS testing method could make water testing more affordable, portable and accessible
University of Massachusetts Amherst researchers have discovered a new way to detect per- and polyfluoroalkyl substances (PFAS) in water. This marks an important step forward in creating testing devices that are simpler, more cost-effective, faster an.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
Gamma radiation converts methane into complex organic molecules and could explain the origin of life
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, according to a new article published in the journal Angewandte Chemie International Edition.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
Soil sampling in Houston"s greater Fifth Ward reveals toxic levels of lead in yards, play areas
Houston, like many American cities, has areas with soil contaminated by non-biodegradable and persistent pollutants such as arsenic, lead, nickel and cadmium, known as heavy metals and metalloids. These are both naturally occurring in the atmosphere.....»»
Hubble and Webb are the dream team—don"t break them up, researchers say
Many people think of the James Webb Space Telescope as a sort of Hubble 2. They understand that the Hubble Space Telescope (HST) has served us well but is now old and overdue for replacement. NASA seems to agree, as they have not sent a maintenance m.....»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Future space telescopes could be made from thin membranes, unrolled in space to enormous size
Space-based telescopes are remarkable. Their view isn't obscured by the weather in our atmosphere, and so they can capture incredibly detailed images of the heavens. Unfortunately, they are quite limited in mirror size......»»
Cobalt-copper tandem system offers sustainable approach for converting carbon dioxide to ethanol
The continuing release of carbon dioxide into the atmosphere is a major driver of global warming and climate change with increased extreme weather events. Researchers at Johannes Gutenberg University Mainz (JGU) have now presented a method for effect.....»»
The world promised to tame methane: Emissions are still rising
Sitting in his cramped office in Paris, Manfredi Caltagirone admits that one of the world's highest-profile efforts to cut methane emissions so far isn't stopping the gas from escaping and warming the atmosphere......»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
Cybersecurity in crisis: Are we ready for what’s coming?
In this Help Net Security video, James Edgar, CISO at Corpay, reveals insights into cybersecurity health, concerns, challenges, and other considerations for building a solid defense program. Key insights revealed in Corpay’s 2024 State of Busin.....»»
Scientists detect traces of an ancient Mayan city in southern Mexico using laser-sensor technology
Archaeologists using laser-sensing technology have detected what may be an ancient Mayan city cloaked by jungle in southern Mexico, authorities said Wednesday......»»
Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»
