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.....»»
TCP J1822 is a symbiotic star, observations find
Using the Himalayan Chandra Telescope (HCT), Indian astronomers have conducted spectroscopic observations of a star discovered in 2021, known as TCP J1822. Results of the observational campaign indicate that TCP J1822 is a symbiotic star. The finding.....»»
Best of Last Year: The top Phys.org articles of 2023
It was a good year for research across multiple fields as a team at the University of Ottawa, working with colleagues Danilo Zia and Fabio Sciarrino, from the Sapienza University of Rome, demonstrated a novel technique to visualize the wave function.....»»
Research finds marine bacteria, atmospheric rivers can contribute to formation of ice clouds
Understanding cloud formation in polar regions is essential to discern the influence of solar radiation on the polar ice caps. Existing numerical models, however, struggle to replicate ice clouds accurately. Now, using real-world observations and cli.....»»
NuHarbor Security partners with Zscaler to protect distributed workforces
NuHarbor Security has partnered with Zscaler to deliver a new level of cybersecurity capability and business value based on the proven effectiveness of the largest security cloud on the planet. Combining NuHarbor’s nationally recognized leadership.....»»
Large exomoons unlikely around Kepler-1625 b and Kepler-1708 b, astronomers say
Only two of the more than 5,300 known exoplanets have so far provided evidence of moons in orbit around them. In observations of the planets Kepler-1625b and Kepler-1708b from the Kepler and Hubble space telescopes, researchers discovered traces of s.....»»
Astronomers discover galaxies have bipolar gas outflows reaching far into intergalactic space
Astronomers have observed, for the first time in three dimensions, that gas from spiral galaxies is blown upward and downward at high velocity, far out of the galaxy. The observations confirm the prevailing theory of galaxy evolution that says that s.....»»
Forecasting forest health using models to predict tree canopy height
Tree height is an important indicator of a forest's maturity and overall health. Forest restoration projects rely on tree height as a predictor and measurement of success, but forecasting a forest's future tree height based on observations alone is a.....»»
Satellite observations reveal latitudinal variability and asymmetry in local temperature responses to land cover changes
Land cover changes (LCCs) affect surface temperatures at local scale through biophysical processes. However, limited by the coarse spatial resolution of available data, past observation-based studies mainly focused on the potential effects of virtual.....»»
Report: 1.5°C pathways can still be achieved while combining fairness and global climate protection
Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies us.....»»
Neptune-sized exoplanet is too big for its host star
Stars this small shouldn't make planets this big. Enlarge (credit: NASA/JPL-Caltech) You win some, you lose some. Earlier this week, observations made by the Webb Space Telescope provided new data that supports what we t.....»»
Pickier dogs found to have pickier brains
Dogs' food preferences are mirrored in their brain activity, particularly within their caudate nuclei -a brain region associated with reward processing, a new study combining behavioral and neuroimaging data by researchers from the Department of Etho.....»»
An anisotropic density turbulence model from the sun to 1 au derived from radio observations
Density turbulence in the solar corona and solar wind is evident via the properties of solar radio bursts; angular scattering-broadening of extra-solar radio sources observed through the solar atmosphere, and can be measured in-situ in the solar wind.....»»
Astronomers inspect supernova remnants with MeerKAT
Using the MeerKAT radio telescope, astronomers from the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, and elsewhere have investigated a batch of 36 high latitude supernova remnants. Results of the observations campaign, pu.....»»
Using gravitational wave observations of a binary black hole merger to verify the no-hair theorem
An international team of researchers including Prof. Badri Krishnan at Radboud University has verified an important property of black holes known as the no-hair theorem using gravitational wave observations. Their research is published in the journal.....»»
Community scientists needed: Help improve winter weather predictions
Community members across Utah, the Great Basin, and around Lake Erie and Lake Ontario are invited to join people across the country in contributing winter weather observations. The data is collected by scientists for a project that seeks to improve t.....»»
Observations find evolving material, not rings, circling Centaur Chiron
Observations during a stellar occultation detected the presence of evolving material orbiting around Centaur (2060) Chiron, rather than a two-ring system interpretation, according to a paper by Planetary Science Institute Senior Scientist Amanda Sick.....»»
Blending statistical studies of piglet gut bacteria reveals patterns at key growth stages
An analysis combining the results of 14 studies from around the globe has uncovered some common patterns in how the piglet microbiome, specifically the gut bacteria, changes over time......»»
Alien haze, cooked in a lab, clears view to distant water worlds
Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles observations by ground and space telescopes......»»
Groundbreaking method to match celestial objects across telescopes
A team of Johns Hopkins researchers has developed a cutting-edge data science approach capable of matching observations of celestial objects taken across multiple telescope surveys, overcoming a significant challenge in modern astronomy......»»
Study shows plants use air channels to create a directional light signal and regulate phototropism
Plants have no visual organs, so how do they know where light comes from? In an original study combining expertise in biology and engineering, the team led by Prof Christian Fankhauser at UNIL, in collaboration with colleagues at EPFL, has uncovered.....»»
