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.....»»
Scientists discover planet orbiting closest single star to our sun
Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our sun. On this newly discovered exoplanet, which has at least half the mass of.....»»
Increased sea surface cooling from hurricanes observed along the Southeast Coast of the United States in recent decades
Utilizing satellite observations and ocean reanalysis datasets, researchers have analyzed the change in sea surface cooling induced by hurricanes and the corresponding ocean-atmosphere environment along the Gulf and Southeast coastal regions of the U.....»»
Study elucidates a mechanism for phosphorus cycling in subtropical forests
Phosphorus (P) is an important nutrient element in plant photosynthesis. However, the adsorption of mineral P via leaching and erosion leads to a decrease in P availability and consequently P deficiency......»»
New mission to create total solar eclipses in space
A UK team of researchers including UCL's Professor Lucie Green are working on the launch of a spacecraft mission that will allow us to view the sun's atmosphere in more detail than ever before......»»
Webb detects fast outflow in the host galaxy of a luminous quasar
An international team of astronomers has employed the James Webb Space Telescope (JWST) to perform spectroscopic observations of a luminous quasar known as J1007+2115. They detected a fast outflow originating from the quasar's host galaxy. The findin.....»»
Another building block of life can handle Venus" sulfuric acid
Venus is often described as a hellscape. The surface temperature breaches the melting point of lead, and though its atmosphere is dominated by carbon dioxide, it contains enough sulfuric acid to satisfy the comparison with Hades......»»
New approach reveals details about aerosol properties from hard-to-sample areas in the atmosphere
The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in.....»»
Study shows Mars" early thick atmosphere could be locked up in the planet"s clay surface
Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have been a thick atmosphere to keep that water from freez.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
An international group of researchers including University of Arizona astronomers, using NASA's James Webb Space Telescope, has observed the atmosphere of a hot and uniquely inflated exoplanet. The exoplanet, which is the size of Jupiter but only a t.....»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electro.....»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
New millisecond pulsar discovered
Using the Green Bank Telescope (GBT), astronomers have observed a globular cluster known as Terzan 6. They detected a new millisecond pulsar that is likely associated with this cluster. The finding was reported in a research paper published September.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur.....»»
Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion
The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy, the Milky Way......»»
Sea surface micro layer: Researchers study boundary between the ocean and the air
The boundary between the ocean and the atmosphere, where the air and sea interact, is known as the sea surface microlayer. Understanding how nutrients, pollutants and organic matter are exchanged between the air and the sea is also vital for better u.....»»
