Arecibo Observatory telescope outfitted with a wideband cryogenic system to expand its capabilities
Constructed within a natural sinkhole in Puerto Rico, the 305-meter-wide Arecibo Telescope played a part in numerous discoveries, including the first detection of an exoplanet. It was the largest radio telescope in the United States from 1963 until i.....»»
New cataclysmic variable discovered by astronomers
By analyzing the data from ESA's XMM-Newton and Gaia satellites, astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany and elsewhere have detected a new magnetic cataclysmic variable system, most likely of the polar type. T.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Faintest known star system orbiting the Milky Way discovered
A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered,.....»»
New nearby mini-Neptune exoplanet discovered
An international team of astronomers reports the discovery of a new mini-Neptune exoplanet orbiting a nearby star. The newfound alien world, designated TOI-4438 b is about 2.5 times larger than the Earth. The finding was detailed in a paper published.....»»
Team reports on the occurrence of antibiotic resistance genes in the western Qinghai Lake basin
Antibiotic resistance genes (ARGs) have been widely detected in water, sediment, gut and even the phycosphere of algae. In strong anthropogenic activity areas, antibiotic resistance caused by ARGs can pose a significant threat to human health. Despit.....»»
Webb finds hints of a third planet at PDS 70
The exoplanet census now stands at 5,599 confirmed discoveries in 4,163 star systems, with another 10,157 candidates awaiting confirmation. So far, the vast majority of these have been detected using indirect methods, including transit photometry (74.....»»
Could Earth life survive on a red dwarf planet?
Even though exoplanet science has advanced significantly in the last decade or two, we're still in an unfortunate situation. Scientists can only make educated guesses about which exoplanets may be habitable. Even the closest exoplanet is four light-y.....»»
Higher bacterial counts detected in single-serving milks
Cornell University scientists have detected higher bacterial counts in commercial, paperboard single-serving containers two weeks after processing than in milk packaged in larger containers from the same facilities......»»
Astronomers discover new Saturn-sized exoplanet
An international team of astronomers reports the discovery of a new exoplanet orbiting a solar-type star. The newfound alien world, designated TOI-1135 b is young, hot and comparable in size to Saturn. The discovery was detailed in a paper published.....»»
Study shows that the ATLAS detector can measure the flux of high-energy supernova neutrinos
High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013......»»
Security Bite: Self-destructing macOS malware strain disguised as legitimate Mac app
Security researchers at Moonlock, the relatively new cybersecurity wing of MacPaw, have detected a new strain of macOS malware disguised as a legitimate Mac app that can destroy itself in certain conditions. At its worst, it can unknowingly extract c.....»»
If exoplanets have lightning, it"ll complicate the search for life
Discovering exoplanets is almost routine now. We've found over 5,500 exoplanets, and the next step is to study their atmospheres and look for biosignatures. The James Webb Space Telescope is leading the way in that effort. But in some exoplanet atmos.....»»
Astronomers detect an extremely red supermassive black hole in the early universe growing in the shadows
Analyzing images from the James Webb Space Telescope (JWST), a group of astronomers led by Dr. Lukas Furtak and Prof. Adi Zitrin from Ben-Gurion University of the Negev has detected an extremely red, gravitationally lensed supermassive black hole in.....»»
Possible atmospheric destruction of a potentially habitable exoplanet
Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the planet, likely leaving the.....»»
Scientists find evidence of geothermal activity within icy dwarf planets
A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or ev.....»»
Physicists detect elusive "Bragg glass" phase with machine learning tool
Cornell quantum researchers have detected an elusive phase of matter, called the Bragg glass phase, using large volumes of X-ray data and a new machine learning data analysis tool. The discovery settles a long-standing question of whether this almost.....»»
Chinese astronomers find radio pulsar in a supernova remnant
