ALMA successfully restarts observations after cyberattack
Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected JAO computer system servers and.....»»
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.....»»
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.....»»
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.....»»
Lift-off for EIRSAT-1, Ireland"s first ever satellite
Six years of hard work and dedication paid off in spectacular fashion on Dec. 1 as the Educational Irish Research Satellite, EIRSAT-1, successfully blasted off from Vandenberg Space Force Base, California. Hitching a ride on a Space-X Falcon-9 launch.....»»
"DNA curtain" technology provides real-time visualization of replication for new scientific insights
A research team, led by Professor Ja Yil Lee in the Department of Biological Sciences at UNIST has made a breakthrough in the field of molecular biology. Their research, published in the journal Nucleic Acids Research, has successfully imaged the rea.....»»
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.....»»
Ransomware group threatens Yanfeng after claiming cyberattack
Qilin, a ransomware operation known to breach firms in critical sectors via phishing emails, added Yanfeng to its extortion portal Monday......»»
Contact binary asteroids are common, but we"ve never seen one form. Now, researchers want to make one
Ever want to play a game of cosmic billiards? That's commonly how the DART mission was described when it successfully changed the orbit of a near-Earth asteroid last year. If you want an idea of how it works, just Google it and an Easter egg from the.....»»
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.....»»
After 50 years, US to return to moon on January 25
More than 50 years after the last Apollo mission, the United States will try once again to land a craft on the moon on January 25, said the head of what could be the first private company to successfully touch down on the lunar surface......»»
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.....»»
Vigil: Open-source LLM security scanner
Vigil is an open-source security scanner that detects prompt injections, jailbreaks, and other potential threats to Large Language Models (LLMs). Prompt injection arises when an attacker successfully influences an LLM using specially designed inputs......»»
Research unveils nickel-based catalysts with remarkable economic feasibility
In a development set to transform the chemical industry on a global scale, Professor Chang Ho Yoo in the Department of Chemistry at UNIST has successfully developed a highly efficient and stable carbonylation catalytic reaction using nickel catalysts.....»»
Data from NASA’s Webb Telescope backs up ideas on planet formation
