Gamma-ray emission detected from the supernova remnant G272.2-3.2
Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have detected significant GeV gamma-ray emission from a supernova remnant (SNR) known as G272.2-3.2. The finding is detailed in a paper published March 29 on the arXiv pre-print reposi.....»»
International SWOT satellite spots planet-rumbling Greenland tsunami
The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France's CNES (Center National d'Études Spatiales), detected the unique contours of a tsunami that sloshed within the steep walls of a fj.....»»

New extended and faint tidal tail discovered
By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. The finding was reported.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
Scientists provide direct evidence of breakdown of spin statistics in ion-atom charge exchange collisions
Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in collisions between highly charged ions and atoms or molecules has emerged as a hot research topic......»»
A global imbalance in reference genomes: Research highlights need for sequencing resources in biodiversity-rich areas
Montana State University and Universidad de los Andes researchers have detected a significant imbalance in the distribution of tetrapod reference genomes. They find a disproportionate concentration of studies in high-latitude regions compared to wher.....»»
Seeing a black hole"s jet in a new light: A look at high-energy particles being blasted across space
Research led by the University of Michigan has pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black holes......»»

Apple’s next-gen M4 Macs look set to embrace serious gaming
Apple's next-generation M4 silicon will serve ray tracing, even on the Mac mini. We might also get some relief with Apple's stingy RAM approach, too......»»
Astronomers take a close look at a dandelion-shaped supernova and zombie star
In 1181, a new star shone near the Cassiopeia constellation for six months before disappearing. This event, recorded as a "guest star" by Chinese and Japanese observers almost a millennium ago, has puzzled astronomers for centuries. It is one of a fe.....»»
Poaching suspected as camera traps find only 11 Sumatran tigers in 2 years
Camera-trap monitoring detected only 11 individual Sumatran tigers (Panthera tigris sumatrae) and no cubs between 2020 and 2022 in the Ulu Masen Ecosystem, Sumatra Island, Indonesia, reports a paper published in Scientific Reports. The high proportio.....»»
Astronomers discover a bright pulse that may be a fast radio burst
Searching for pulsars using the Large Phased Array (LPA) radio telescope, Russian astronomers have detected a bright pulse at a frequency of 111 MHz, which appears to be a fast radio burst event. The finding was reported in a research paper published.....»»

X-ray spectroscopy study maps ultrafast charge delocalization in aqueous environments
The movement of electron density is a subject of interest for chemists worldwide, as substances interact through electrons. These processes are ultrafast and traditionally require time-resolved experiments at the attosecond level to study and describ.....»»
Betelgeuse Betelgeuse? Bright star Betelgeuse likely has a "Betelbuddy" stellar companion
One of the brightest stars in the night sky, Betelgeuse, may not be on the brink of exploding as a supernova, according to a new study of the star's brightening and dimming. Instead, recent research shows that the observed pulsing of the starlight is.....»»
Invasive flathead catfish impacting Susquehanna"s food chain, researchers find
Flathead catfish—native to the Mississippi River basin—were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the ri.....»»
