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,.....»»
A 15-user quantum secure direct communication network
Quantum secure direct communication (QSDC) based on entanglement can directly transmit confidential information. Scientist in China explored a QSDC network based on time-energy entanglement and sum-frequency generation. The results show that when any.....»»
Unveiling galaxies at cosmic dawn that were hiding behind the dust
When astronomers peer deep into the night sky, they observe what the universe looked like a long time ago. Because the speed of light is finite, studying the most distant observable galaxies allows us to glimpse billions of years into the past when t.....»»
NASA"s Artemis rover will explore permanently shadowed region of the Moon
NASA said the Moon’s South Pole is one of the coldest environments in our solar system. No other missions to the surface of the Moon have explored the region; thus far, scientists have only been able to study it from afar using instruments attached.....»»
Dashcam detective work leads to recovery of space rocks from fireball over Slovenia
On 28 February 2020, at 10:30 CET, hundreds of people across Slovenia, Croatia, Italy, Austria and Hungary observed a bright ball of light hurtling across the morning sky. This delivery of rocks from a distant asteroid to the fields and villages of s.....»»
First complete national assessment of Australia"s sharks and rays
The first complete assessment of extinction risk for all Australian sharks, rays and ghost sharks reveals Australia is home to more than a quarter of shark species on the planet, but 12 percent of those are at risk of extinction......»»
Alphabet"s Project Taara beamed 700TB of fiber-like Internet with 99.9 percent uptime
Google has explored plenty of daring projects over the years, but most of them never see any commercial implementation beyond a few trial runs. That's because the company has cultivated a culture of embracing failure as a way to test ideas and quickl.....»»
Burning space mystery solved as researchers confirm origins of "empty sky" gamma-rays
Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed......»»
Cosmic rays erode away all but the largest interstellar objects
So far, we know of only two interstellar objects (ISO) to visit our solar system. They are 'Oumuamua and 2I/Borisov. There's a third possible ISO named CNEOS 2014-01-08, and research suggests there should be many more......»»
Study inspects galaxy protocluster PHz G237.01+42.50
An international team of astronomers has performed spectroscopic observations of a distant galaxy protocluster known as PHz G237.01+42.50. Results of the study, presented in a paper published September 9 on the arXiv pre-print server, yield essential.....»»
Astronomers spot the same supernova three times—and predict a fourth sighting in 16 years
An enormous amount of gravity from a cluster of distant galaxies causes space to curve so much that light from them is bent and emanated our way from numerous directions. This "gravitational lensing" effect has allowed University of Copenhagen astron.....»»
Solar "Superflares" Rocked Earth Less Than 10,000 Years Ago--and Could Strike Again
Although our sun is considered a quiet star, it is now thought to have repeatedly pelted our planet with enormous eruptions in the not too distant past. Could another occur in the near future? -- Read more on ScientificAmerican.com.....»»
Bringing together the powers of electrochemistry and flow technology
The combination of electrochemistry and flow technology holds much promise for the sustainable production of valuable chemicals, such as biobased feedstocks. Researcher Yiran Cao has explored electrochemical organic synthesis in flow, and especially.....»»
Fans Ask Questions After First Trailer Released for "The Matrix Resurrections"
Moviegoers know that the Matrix trilogy's finale "heavily hinted that our hero will be back at some point in the distant future," writes the Guardian.. "Now he is..." But does the first three-minute trailer for the soon-to-be-released sequel The Mat.....»»
Stars sparkle and shine in Hubble image of a distant globular cluster

Samsung Galaxy Watch 4 Classic: A well-rounded smartwatch
For smartwatches, it’s Apple against the world. Per recent numbers from CounterPoint, the Apple Watch commanded more than one-third of global shipments in Q1. Samsung/Tizen’s own market share is a distant — but respectable — second pl.....»»
Never-before-seen radio waves detected from nearby stars and distant galaxies
Scientists have measured thousands of nearby stars and far away galaxies that have never been identified before at radio wavelengths, while studying a galactic body that neighbors our own Milky Way galaxy—the Large Magellanic Cloud......»»
Exploring how tantalum behaves at high pressures and temperatures
Lawrence Livermore National Laboratory (LLNL) researchers have explored high-pressure behavior of shock-compressed tantalum at the Omega Laser Facility at the University of Rochester's Laboratory for Laser Energetics (LLE). The work showed tantalum d.....»»
