Heaviest element yet detected in an exoplanet atmosphere
Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered the heaviest element ever found in an exoplanet atmosphere—barium. They were surprised to discover barium at high altitudes in the atmospheres o.....»»
A review of the applications of mercury stable isotopes for tracing volcanism in geologic events
Mercury is a toxic heavy metal that can exist stably as a gas, with high volatility and global distribution in the atmosphere. Volcanoes represent a primary natural source of Hg in the atmosphere, with significant effects on Hg cycles on both global.....»»

A surprisingly low amount of methane and a super-sized core hide within the cotton candy–like planet WASP-107 b......»»
Webb cracks case of inflated exoplanet
Why is the warm gas-giant exoplanet WASP-107 b so puffy? Two independent teams of researchers have an answer......»»
Why Earthlings are safe when huge solar storms strike our planet
When solar storms and coronal mass ejections hit Earth and create the Northern Lights, people are physically protected from radiation by Earth's magnetic field and atmosphere. From time to time, the sun discharges billions of tons of solar matt.....»»
Solar storm detected in deep sea observatories
The powerful solar storm driving the aurora borealis over global skies last weekend was also triggering the movement of compasses deep in the ocean, as revealed in new scientific findings shared today by Ocean Networks Canada (ONC), a University of V.....»»
Three new RR Lyrae variable stars discovered
Using the Lulin One-meter Telescope (LOT), astronomers have observed a newly detected candidate ultra-faint dwarf galaxy known as Virgo III. As a result, they discovered three new RR Lyrae variable stars in the vicinity of this galaxy. The finding wa.....»»
Vision Pro international rollout beckons as China approves release
We’re expecting the Vision Pro international rollout to happen not long after WWDC, and we’ve now seen another element of the plan fall into place. An “Apple wearable computer” has been granted the Chinese quality and safety accreditation.....»»
Astronomers discover new Earth-sized world orbiting an ultra-cool star
An international team of astronomers has detected a new, Earth-sized planet just 55 light years away, orbiting an ultra-cool red dwarf star......»»
Astronomers discover merging twin quasars
Using the Subaru Telescope in Hawaii, astronomers have detected a pair of merging quasars at a high redshift, as part of the Hyper SuprimeCam (HSC) Subaru Strategic Program (SPP) survey. The serendipitous discovery is reported in the latest issue of.....»»
Avian flu detected in New York City wild birds
A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a study published in the Journal of Virology,. The work highlights that the interface between animals and humans that may give rise to zoonotic infe.....»»
Health systems eliminating a form of anesthesia that hangs in the air for more than a decade after use
Philadelphia-area health systems are phasing out a common anesthesia gas that hangs in the atmosphere for 14 years. Desflurane is the most potent greenhouse gas found in hospitals, which are increasingly engaged in efforts to reduce their carbon foot.....»»
Electron vortices in graphene detected for the first time
When an ordinary electrical conductor—such as a metal wire—is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery. While moving, electrons frequently collide with impurity atoms or v.....»»
Brazil authorities warn of more floods, landslides as new rains hit south
New rains in waterlogged southern Brazil are expected to be heaviest between Sunday and Monday, authorities have warned, bringing fresh misery to victims of flooding that has killed 136 people so far......»»
NASA’s Quest to Touch the Sun
The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. NASA sent a probe to find out why—by getting closer to the star than ever before......»»
Tauonium: The smallest and heaviest atom with pure electromagnetic interaction
The hydrogen atom was once considered the simplest atom in nature, composed of a structureless electron and a structured proton. However, as research progressed, scientists discovered a simpler type of atom, consisting of structureless electrons, muo.....»»
Study finds consistent decline in nitrogen oxides emissions from human activities in China since 2020
Nitrogen oxides (NOx) form aerosols and ozone in the atmosphere and are significant contributors to air pollution and climate change. China is the largest emitter, yet accurate and timely information on NOx emissions in China has been lacking since 2.....»»
Probing neptunium"s atomic structure with laser spectroscopy
A new technique developed by researchers in Germany can measure ionization states of this element more precisely than before, with implications for its detection and remediation in radioactive waste......»»
New rhizobia-diatom symbiosis solves long-standing marine mystery
Nitrogen is an essential component of all living organisms. It is also the key element controlling the growth of crops on land, as well as the microscopic oceanic plants that produce half the oxygen on our planet. Atmospheric nitrogen gas is by far t.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
James Webb telescope peers at the atmosphere of a rocky hell world
Webb recently investigated the exoplanet 55 Cancri e, finding what could be the first atmosphere of a rocky planet discovered outside the solar system......»»
