Gravitational-wave scientists propose new method to refine the Hubble Constant—the expansion and age of the universeA team of international scientists, led by the Galician Institute of High Energy Physics (IGFAE) and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), has proposed a simple and novel method to bring the accuracy of the Hubble constant measurements down to 2% using a single obse…

Gravitational wave scientists from The University of Western Australia have led the development of a new laser mode sensor with unprecedented precision that will be used to probe the interiors of neutron stars and test fundamental limits of general relativity.

Verizon has suffered a data breach. A hacker recently accessed the company’s employee database and stole personally identifiable information about hundreds of its employees. The stolen information includes the full name, phone number, email address, and corporate ID numbers.

According to a Motherboard report, the hacker got access to the Verizon database by tricking an employee to grant them remote access to their corporate computer. They posed as internal support and convinced the victim through social engineering. Once the hacker had access to the database, they launched a script to copy the information.

“These employees are idiots,” the hacker told Motherboard in an online chat. They shared the stolen data, perhaps part of it, with the publication. The report suggests the information is accurate but unclear how up to date. The publication called some of the phone numbers and four people confirmed their full names and email addresses. They also confirmed that they work at Verizon.

SpaceX CEO Elon Musk has revealed the first technical details about the company’s next-generation Starlink ‘Gen2’ satellite design, confirming that it will far outmatch the current generation of satellites by almost every measure.

Speaking in an onsite interview and Starbase tour with YouTuber Tim Dodd (The Everyday Astronaut), Musk – largely unprovoked – revealed that SpaceX has already built at least one functional Starlink Gen2/V2.0 satellite prototype and shipped it to the South Texas Starship factory, where it is currently being stored. More importantly, Musk also provided the first direct specifications for the next-generation spacecraft, stating that each Starlink V2.0 satellite will weigh about 1.25 tons (~2750 lb), measure about seven meters (~23 ft) long, and be almost an order of magnitude more capable than the “Starlink 1” satellites they’ll ultimately supersede.

Almost ten months after SpaceX first revealed its updated plans for a next-generation, 30,000-satellite constellation, those details have confirmed a few key points of speculation about the future of Starlink.

China has to have the capability to identify and destroy SpaceX’s Starlink satellites, according to Chinese military experts in a report released in April. The research, headed by Ren Yuanzhen of the Beijing Institute of Tracking and Telecommunications, was published in the Chinese peer-reviewed journal Modern Defence Technology. The publication inexplicably disappeared from the online version of The South China Morning Post after The South China Morning Post reported on its contents.

David Cowhig, a former US ambassador, was able to complete the translation of the document before it vanished, which allowed him to uncover a number of preventative steps that were suggested to be taken against Starlink. According to the study, China has to “use a mix of soft and hard kill measures to disrupt the operating system of the constellation and deactivate part of the Starlink satellites.”

Neutron stars are normally extremely fast-spinning stellar corpses left over from the intense violence of a supernova, but researchers have found one in a “stellar graveyard” where one should not be – and it spins at a relatively glacial rate of once every 76 seconds.

Researchers with the University of Sydney found the bizarre radio signal, designated PSR J0901-4046, emitted by the neutron star thanks to the MeerKAT radio telescope in South Africa and weren’t even expecting to see it. The region of the sky they were observing was thought to be free of pulsars, since none had been observed there before.

Now they might know why. Capturing eight-second-long samples of the sky, they caught sight of a single pulse from the star, which had to be confirmed with subsequent observation due to its unexpectedly long rotational period.

We might be consumed with CPU news with AMD’s upcoming Zen 4-based Ryzen 7,000 series CPUs, teasing a 16-core engineering sample at 5.5GHz+ but now we’re back to GPU rumors again with NVIDIA reportedly launching the higher-end GeForce RTX 4,090 first.

According to the latest from leaker “kopite7kimi”, NVIDIA will reportedly launch the GeForce RTX 4,090 first, then the GeForce RTX 4,080 and GeForce RTX 4,070 after. This would break tradition, as NVIDIA normally launches the x080 and x070 series GPUs first, followed by the x090 series GPU… but the RTX 4,090 launching first makes sense.
