Modeling collisions between argon nuclei and neutrinos from a supernova
Massive stars end their lives in explosions called core-collapse supernovae. These explosions produce very large numbers of weakly interacting particles called neutrinos. Scientists working on the Deep Underground Neutrino Experiment, hosted by Fermi.....»»
Modeling organizations’ defensive mechanisms with MITRE D3FEND
Funded by the National Security Agency, MITRE’s D3FEND framework is helping to provide standardization, specificity, and repeatability needed by cybersecurity engineers. As the framework moves from the beta version to version 1.0 in 2024, we asked.....»»
ALMA observations shed more light on molecular clouds associated with supernova remnant LHA 120-N49
Using the Atacama Large Millimeter/Submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as LHA 120-N49. Results of the observational campaign, published November 3 on the pre-print server arXiv, prov.....»»
Tiny Big Bang: ALICE experiment restarts with lead ions
On September 26, 2023, the accelerator team at the CERN European Council for Nuclear Research in Geneva declared stable lead-beam conditions, ushering in the first data-taking campaign of lead-ion collisions in five years. From then until the late ev.....»»
Faster Arctic warming hastens 2-degree-Celsius rise by eight years, finds modeling study
Faster warming in the Arctic will be responsible for a global 2 C temperature rise being reached eight years earlier than if the region were warming at the average global rate, according to a new modeling study led by UCL researchers......»»
Endangered turtle population under threat as pollution may lead to excess female hatchlings
Green sea turtles, Chelonia mydas, are listed as endangered on the IUCN Red List of Threatened Species. They are at risk of extinction due to poaching, collisions with boats, habitat destruction, and accidental capture in fishing gear......»»
Daily Telescope: A spectacular view of a 10,000-year-old supernova remnant
"Without narrowband filters, it’s almost impossible to photograph." Enlarge / The Garlic Nebula in all its glory. Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough lig.....»»
Astronomers are hoping to detect gravitational waves coming from supernova 1987A
A supernova explosion is a cataclysmic explosion that marks the violent end of a massive star's life. During the event, the star releases immense amounts of energy, often outshining the combined light from all the stars in the host galaxy for a very.....»»
Magnetic shielding for particle detectors
Particle physicists who hunt for neutrinos, cosmic-rays and other charged particles rely on sophisticated instruments that detect very faint bursts of light given off when incident particles interact with a medium. The most common such instruments, c.....»»
Supermassive black hole found only half a billion years after Big Bang
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
Half of the mass of an early galaxy is in its central black hole
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
Searching for the supernova neutrino background to the universe
It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to the end of this article. The more massive stars.....»»
Research explores the properties of supernova remnant 1E 0102.2–7219
Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as 1E 0102.2–7219. Results of the study, presented October 2.....»»
Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
A new Antarctic ice sheet modeling study from scientists at UC San Diego's Scripps Institution of Oceanography suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster......»»
NASA rocket to see sizzling edge of star-forming supernova
A new sounding rocket mission is headed to space to understand how explosive stellar deaths lay the groundwork for new star systems. The Integral Field Ultraviolet Spectroscopic Experiment, or INFUSE, sounding rocket mission, will launch from the Whi.....»»
Research characterizes the footprint of neutrinos
The neutrino, one of nature's most elusive and least understood subatomic particles, rarely interacts with matter. That makes precision studies of the neutrino and its antimatter partner, the antineutrino, a challenge. The strongest emitters of neutr.....»»
Using mathematical modeling to save coral reefs
A team of researchers at the University of Waterloo is using mathematical models to help determine the best strategies for saving coral reefs from climate change......»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
Decline of rare right whale appears to be slowing, but scientists say big threats remain
The decline of one of the rarest whales in the world appears to be slowing, but scientists warn the giant mammals still face existential threats from warming oceans, ship collisions and entanglement in fishing gear......»»
In 250 million years, a single supercontinent will form, wiping out nearly all mammals: Modeling study
A recent study published in Nature Geoscience uses supercomputer climate models to examine how a supercontinent, dubbed Pangea Ultima (also called Pangea Proxima), that will form 250 million years from now will result in extreme temperatures, making.....»»
New 3D-printed tumor model enables faster, less expensive and less painful cancer treatment
