Indian regulators keep pushing antitrust report forward, despite Apple"s hold request
India's antitrust regulators have declined to grant Apple's request for a temporary hold on a report that alleges app developers are compelled to adhere to unfair terms to be on the App Store.India's CCI rejects Apple's request to halt investigation.....»»
Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published November 19 in The Astr.....»»
WEAVE spectrograph uncovers dual nature of galaxy shock
Using the set of first-light observations from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph, a team of more than 50 astronomers, led by Dr. Marina Arnaudova at the University of Hertfordshire, has.....»»
Saturday Citations: Sweaty, remarkable humans; ocean level rise projections; closeup of a star in another galaxy
Since we last spoke, researchers at the University of Birmingham have defined the precise shape of a single photon (spoiler: roundish). Economists worry that Trump's grandiose deportation plans could lead to a recession. And astronomers report that t.....»»
Ted Cruz wants to overhaul $42B broadband program, nix low-cost requirement
Cruz claims grant program is "boondoggle," urges Biden admin to halt activities. Emboldened by Donald Trump's election win, Republicans are seeking big changes to a $42.45 billion.....»»
Discovery of van Hove singularities could lead to novel materials with desirable quantum properties
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the van Hove singularity. These interactions give rise to unusual properties in quantum materials, such as superconductivity at hig.....»»
Ring around Tabby"s star
This illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian's Star or Tabby's Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming.....»»
Hubble finds sizzling details about young star FU Orionis
In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our sun. Unlike an exploding.....»»
Astronomers snap first up-close image of a star outside our galaxy
Astronomers have taken a detailed image of a star outside of the Milky Way for the first time......»»
A nearby supernova could end the search for dark matter
The search for the universe's dark matter could end tomorrow—given a nearby supernova and a little luck. The nature of dark matter has eluded astronomers for 90 years, since the realization that 85% of the matter in the universe is not visible thro.....»»
Are fast radio bursts caused by interstellar objects crashing into neutron stars?
Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were first discovered a couple of decades ago, we had.....»»
Astronomers take first close-up picture of a star outside our galaxy
Located a staggering 160,000 light-years from us, the star WOH G64 was imaged thanks to the impressive sharpness offered by the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI). The new observations reveal a star puffi.....»»
Chandra and Hubble tune into "flame-throwing" Guitar Nebula
Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's Chandra X-ray Observatory and.....»»
Predicting the next supernova explosion: New simulations reveal the physics of supernova shock breakout
Stars with masses between 10 and 30 times that of the sun, in their final evolutionary stages, form an iron core that ultimately collapses into a neutron star. This collapse releases a tremendous amount of gravitational potential energy through neutr.....»»
Observations inspect double-lined spectroscopic binary HD 34736
Using various telescopes, an international team of astronomers has conducted a comprehensive study of a double-lined spectroscopic binary known as HD 34736. The study, published November 6 in the Monthly Notices of the Royal Astronomical Society, del.....»»
First pairs of white dwarf–main sequence binaries discovered in clusters shine new light on stellar evolution
Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—"dead" remnants and "living" stars—in young star clusters. Described in a new study published in The Astrophysical Journal, t.....»»
Microsoft and Atom Computing combine for quantum error correction demo
New work provides a good view of where the field currently stands. In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum erro.....»»
New giant radio galaxy discovered with MeerKAT
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not been reported before. The f.....»»
