Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
Mathematical model provides bolt of understanding for lightning-produced X-rays
In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons—the same type used for medical imaging. Researchers could recreate this phenomenon in the lab, but they could not fully explain how and why.....»»
Connecting distant silicon qubits for scaling up quantum computers
In a demonstration that promises to help scale up quantum computers based on tiny dots of silicon, RIKEN physicists have succeeded in connecting two qubits—the basic unit for quantum information—that are physically distant from one another......»»
The first JWST spectrum of the GRB 221009A afterglow
Gamma-ray bursts are the most energetic and luminous events known to occur in the Universe. Short-lived flashes of gamma rays that typically last from a a tenth of a second to less than an hour, gamma-ray bursts may for a brief period of time outshin.....»»
Bright gamma ray burst confounds models of black hole birth
Last October, following one of the brightest flashes of gamma rays ever observed in the sky, telescopes around the world captured a wealth of data from an event that is thought to herald the collapse of a massive star and the birth of a black hole......»»
An archaeological rediscovery offers clues about distant human past
In their recent publication in the Journal of Human Evolution, UConn Department of Anthropology Professor Christian Tryon and Shara Bailey, Director of the Center for the Study of Human Origins at New York University, detail new findings about 40,000.....»»
For the first time, astronomers have linked a mysterious fast radio burst with gravitational waves
We have just published evidence in Nature Astronomy for what might be producing mysterious bursts of radio waves coming from distant galaxies, known as fast radio bursts or FRBs......»»
The multiverse: How we"re tackling the challenges facing the theory
The idea of a multiverse consisting of "parallel universes" is a popular science fiction trope, recently explored in the Oscar-winning movie "Everything Everywhere All At Once." However, it is within the realm of scientific possibility......»»
A new and efficient particle resuspension prediction model based on quasi-static moment equilibrium
A team of researchers explored the resuspension mechanism of deposited particles under the action of airflow. Using advanced image detection technology and numerical simulation method, a particle resuspension model based on quasi-static moment equili.....»»
"Terminator zones" on distant planets could harbor life, astronomers say
In a new study, University of California, Irvine astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the "terminator zone," which is a ring on planets that have one side that al.....»»
Water was present in our solar system before the sun formed
Astronomers are looking to a distant star system still in the planet-forming phase to understand how water came to be on Earth......»»
The likelihood of academies of science recognizing the work of women researchers is improving
A researcher at the University of the Basque Country (UPV/EHU) has explored how the gender gap has evolved in two American academies: the National Academy of Science (NAS) and the Academy of Arts and Sciences (AAAS) in the election of academics in ps.....»»
Distant star TOI-700 has two potentially habitable planets orbiting it
NASA recently announced the discovery of a new, Earth-sized planet in the habitable zone of a nearby star called TOI-700. We are two of the astronomers who led the discovery of this planet, called TOI-700 e. TOI-700 e is just over 100 light years fro.....»»
Powerful yet lonely: The distant quasar left alone in its group
Looking at the night sky with the naked eye, we can only see an infinitesimal part of what the Universe contains, and the largest part cannot even be "seen". Radio wavelengths have gifted us some of the most fascinating astronomical sources: radio-lo.....»»
Does current shellfish anti-predator gear curb "crunching" rays?
According to NOAA Fisheries, more than 80 percent of marine aquaculture production in the United States consists of bivalve mollusks such as oysters, clams and mussels. However, it's not just humans who enjoy eating these shellfish, so do marine rays.....»»
NASA"s Curiosity views first "sun rays" on Mars
Martian sunsets are uniquely moody, but NASA's Curiosity rover captured one last month that stands out. As the sun descended over the horizon on Feb. 2, rays of light illuminated a bank of clouds. These "sun rays" are also known as crepuscular rays,.....»»
James Webb captures an extremely distant triple-lensed supernova
Webb imaged a huge galaxy cluster located 3.2 billion light-years away, which is acting like a magnifying glass and showing a far-off supernova in triplicate......»»
Rare quasar triplet forms one of the most massive objects in the universe
Ultra-massive black holes are the most massive objects in the universe. Their mass can reach millions and billions of solar masses. Supercomputer simulations on Texas Advanced Computing Center (TACC)'s Frontera supercomputer have helped astrophysicis.....»»
Study shows promising results in using the sun"s ultraviolet rays to decontaminate water at high altitudes
Research shows that solar water disinfection (SODIS) may be just as effective at decontaminating Escherichia coli (E coli) infected water at high altitudes as it is at low altitudes. The results of a new study appearing in the Wilderness Medical Soci.....»»
Social media provides space for "digital cosmopolitanism," argue researchers
Social media platforms such as Facebook and Twitter have repeatedly been the subject of negative news coverage. As a result, the positive aspects associated with digital platforms have been overlooked. In light of this, a recent study has explored th.....»»
