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,.....»»
Astronomers inspect a powerful radio-loud high-redshift quasar
Using the European VLBI Network (EVN), an international team of astronomers has performed high-resolution imaging observations of a powerful and radio-loud high-redshift quasar known as J2102+6015. Results of the observational campaign, presented Jan.....»»
Researchers measure boron flux in high-energy cosmic rays with the CALorimetric Electron Telescope (CALET)
Cosmic rays (CR) constitute high-energy particles that mainly originate outside our solar system. These primary CR interact with interstellar matter to produce secondary CR. The secondary nature of their origin is reflected in the higher abundance of.....»»
Astronomers confirm age of most distant galaxy using oxygen
A new study led by a joint team at Nagoya University and the National Astronomical Observatory of Japan has measured the cosmic age of a very distant galaxy. The team used the ALMA radio telescope array to detect a radio signal that has been travelin.....»»
New modeling study shows that most plastic debris on Seychelles beaches comes from far-off sources
Vast amounts of plastic debris accumulate on beaches across the Seychelles and other small island developing states. Observational analysis (for instance, plastic bottle labels) suggest that much of this waste originates from distant sources and not.....»»
A new, better technology for X-ray laser pulses
The X-rays used to examine a broken leg in hospital are easy to produce. In industry, however, X-ray radiation of a completely different kind is needed—namely, X-ray laser pulses that are as short and high-energy as possible. They are used, for exa.....»»
The mechanism of cosmic magnetic fields explored in the laboratory
Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent research shows that mag.....»»
Lethal pathogen causes widespread biological disruption for frogs, but responses differ by species
A new study by a Western Sydney University researcher has explored a lethal fungal pathogen causing widespread biological disruption for frogs, assessing how responses differ by species across the globe......»»
Two thirds of reef sharks and rays risk extinction: Study
Nearly two thirds of the sharks and rays that live among the world's corals are threatened with extinction, according to new research published Tuesday, with a warning this could further imperil precious reefs......»»
Record-breaking detection of radio signal from atomic hydrogen in extremely distant galaxy
Astronomers from McGill University in Canada and the Indian Institute of Science (IISc) in Bengaluru have used data from the Giant Meterwave Radio Telescope (GMRT) in Pune to detect a radio signal originating from atomic hydrogen in an extremely dist.....»»
A team of physicists devise a model that maps a star"s surprising orbit about a supermassive black hole
Hundreds of millions of light-years away in a distant galaxy, a star orbiting a supermassive black hole is being violently ripped apart under the black hole's immense gravitational pull. As the star is shredded, its remnants are transformed into a st.....»»
Discovery of three faint, distant galaxies may expand knowledge of early universe
The discovery of the faintest known galaxies beyond the neighborhood of the Milky Way could help scientists develop universal models for how the universe's oldest galaxies formed, according to findings announced Jan. 11 at the 241st meeting of the Am.....»»
Gaia helps discover directly imaged planet undergoing nuclear fusion
Scientists have used the subtle movements of a distant star to help discover a new exoplanet—which is displaying signs of undergoing nuclear fusion in its core......»»
To the Stars: Making A Stained Glass Space Shuttle
Space. For most, it is the final frontier. For others, it remains a distant galaxy far, far away. But for some, like the creative team of Nicole and Thure of When Geeks Craft, it is a destination already reached. Their stained-glass, fully-lit repl.....»»
Astronomers find the most distant stars in our galaxy halfway to Andromeda
Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way's stellar halo. The most distant of these stars is more than a million light years from Earth, almost half the distance to our neighboring galax.....»»
Negative online reviews from Black people perceived as less credible, according to new study
Consumers are less likely to perceive a negative review from someone of a Black background as credible, according to a first-of-a-kind study which explored the impact of showing race in online profile pictures and avatars......»»
Bayesian inference massively cuts time of X-ray fluorescence analysis
How can the component elements of an unknown material, such as a meteorite, be determined? X-ray fluorescence analysis can be used to identify an abundance of elements, by irradiating samples with X-rays and analyzing the spectrum they emit, detectin.....»»
Researchers inspect gamma-ray flares of the blazar 3C 279
Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the Publications of the Astron.....»»
$48 Apple Watch Ultra clone is ‘designed with perfection’ so you can ‘explore the un-explored’
The next Apple clone has arrived, this time a carbon copy of the company’s Ultra wearable. What may be most laughable are the bold claims that the $48 copycat has been “designed with perfection” so you can “explore the un-explored” and “.....»»
Blu-ray player gathering dust? Turn it into a laser-scanning microscope
Not as powerful as a commerical one, but thousands cheaper. Enlarge (credit: Getty) Blu-rays never quite managed to usurp DVDs entirely. Recent estimates, based on data gathered by Nielsen VideoScan and MediaPlayNews, s.....»»
Disproportionately large amounts of carbon accumulate at the bottom of deep-sea trenches, research shows
The Earth's deep-sea trenches are some of the least explored places on Earth—as they are very difficult to access, are pitch black and the pressure is extremely high. Collecting samples and making reliable measurements of the processes that regulat.....»»
