Combining observations to better visualize a superflare
A team of Japanese astronomers used simultaneous ground-based and space-based observations to capture a more complete picture of a superflare on a star. The observed flare started with a very massive, high-velocity prominence eruption. These results.....»»
Astronomers detect radio halo in a massive galaxy cluster
An international team of astronomers has performed radio observations of a massive galaxy cluster known as ACT-CL J0329.2-2330, which resulted in the detection of a new radio halo in this cluster. The finding was reported in a research paper publishe.....»»
Zscaler extends zero trust SASE and eliminates the need for firewall-based segmentation
Zscaler has signed an agreement to acquire Airgap Networks. Combining Zscaler’s zero trust SD-WAN and Airgap Networks’ agentless segmentation technology will transform how enterprises implement zero trust segmentation to IoT/OT devices, and criti.....»»
The heat is on: What we know about why ocean temperatures keep smashing records
Over the last year, our oceans have been hotter than any time ever recorded. Our instrumental record covers the last 150 years. But based on proxy observations, we can say our oceans are now hotter than well before the rise of human civilization, ver.....»»
Satellite observations show climatological characteristics of isolated deep convection over Tibetan Plateau
The Tibetan Plateau is a prevalent region for deep convection owing to its unique thermodynamic forcing. Deep convection can exist as isolated deep convection (IDC), which is small in size, or mesoscale convective systems (MCSs), which are convective.....»»
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.....»»
A natural touch for coastal defense: Hybrid solutions may offer more benefits in lower-risk areas
Common "hard" coastal defenses, like concrete sea walls, might struggle to keep up with increasing climate risks. A new study published in Nature Communications shows that combining them with nature-based solutions could, in some contexts, create def.....»»
Inexplicable cloud of magnetized plasma found in Hydra galaxy cluster
High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma wil.....»»
Climate change threatens Antarctic meteorites
Using artificial intelligence, satellite observations, and climate model projections, a team of researchers from Switzerland and Belgium calculate that for every tenth of a degree of increase in global air temperature, an average of nearly 9,000 mete.....»»
How Will the Solar Eclipse Affect Animals? NASA Needs Your Help to Find Out
NASA’s Eclipse Soundscapes project will collect observations and soundscapes recorded by the public during the April 8 total solar eclipse......»»
JWST observations explore molecular outflows of a nearby merging galaxy
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby merging galaxy known as NGC 3256. Results of the observational campaign, presented March 21 on the pre-print server arXiv, yield essential informa.....»»
Atmospheric observations in China show rise in emissions of a potent greenhouse gas
To achieve the aspirational goal of the Paris Agreement on climate change—limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels—will require its 196 signatories to dramatically reduce their.....»»
Image: Hubble spots the Spider Galaxy
This image from the NASA/ESA Hubble Space Telescope shows the gauzy-looking celestial body UGC 5829, an irregular galaxy that lies about 30 million light-years away. Despite the lack of observations of this relatively faint galaxy, UGC 5829 has a dis.....»»
Persian plateau unveiled as crucial hub for early human migration out of Africa
A new study combining genetic, paleoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa......»»
New analysis sees spike in 2023 global sea level due to El Niño
A long-term sea level dataset shows ocean surface heights continuing to rise at faster and faster rates over decades of observations......»»
Astronomers confirm a new "Trojan" asteroid that shares an orbit with Mars
Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accom.....»»
Astronomers explore stellar populations of an extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented in a paper published Marc.....»»
Eyes open and toes out of water: How a giant water bug reached the island of Cyprus
The island of Cyprus, although considered a hotspot for biodiversity in the Mediterranean, is more famous for its beautiful sunny coasts than for its insect fauna. Nevertheless, some visitors of its highly populated beaches, with their observations a.....»»
Elephant calves have been found buried. What does that mean?
The myth of elephant graveyards has pervaded popular culture, and recent observations of buried Asian elephant calves may finally give that legend some credence......»»
JWST observations shed more light on the nature of a distant galaxy cluster
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational campaign, described in a pape.....»»
