Webb spots 'Infinity Galaxy' that sheds light on black hole formation

engadget.com Unknown 2025-07-27 00:39:00

Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they dubbed the Infinity Galaxy. It appears to support a leading theory on how some supermassive black holes form. Although "Infinity Galaxy" sounds like a place Thanos would hang out, it merely describes its appearance. Two compact, red nuclei, each surrounded by a ring, give the cluster the shape of an infinity symbol. What's inside is more interesting. (After all, this is a

LIGO detects most massive black hole merger to date

news.ycombinator.com Unknown 2025-07-28 19:06:51

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detected during the fourth observing run of the LVK network on November 23, 2023. LIGO, the Laser Interferometer Gravitational-wave Observatory, made history i

Scientists Detect Sign of Something Impossible Out in Deep Space

futurism.com Unknown 2025-07-29 07:36:51

The very concept of black holes seems improbable. Albert Einstein infamously refused to believe they could exist, even though his theory of general relativity was instrumental in predicting them. Now, scientists have witnessed evidence of something about these baffling cosmic monstrosities that further stretches the boundaries of both physics and credulity: a titanic collision of two already enormous black holes so utterly extreme that it has scientists wondering if the event they seem to have

Black hole merger challenges our understanding of black hole formation

news.ycombinator.com Gayoung Lee 2025-07-30 11:38:20

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to reach our own detectors here on Earth. Today, the LIGO Collaboration announced the detection of the most colossal black hole merger known to date, the final product of which

Configuring Split Horizon DNS with Pi-Hole and Tailscale

news.ycombinator.com Ben Tasker 2025-08-04 23:08:54

I've long had some form of VPN for my devices to use when I'm out and about. Although I used to run OpenVPN, I moved to Tailscale a little while back. Tailscale builds a mesh network using Wireguard protocol and so is able to connect and run quite a bit faster than OpenVPN. Side note: for those wondering, Tailscale is Canadian and can't see the content of connections (although if you're worried about this it's also possible to self-host using Headscale).

Playdate Season 2 review: Taria & Como and Black Hole Havoc

engadget.com Unknown 2025-08-10 21:00:42

We've officially made it to the end of Playdate Season Two, and what a season it's been. Despite having half the number of titles as Season One, this latest round of weekly game releases has made a much stronger impression (on me, at least). If nothing else, it's just been cool to experience the new games in real time with other Playdate owners all at once, which the staggered rollout of the console didn't really allow for with the first season. In an email ahead of the final release, the team a

Nobel Prize Winner Warns About Astronomers Using AI to Make Discoveries

futurism.com Unknown 2025-08-31 20:08:57

A team of astronomers say they've gleaned the mysterious traits of our galaxy's black hole by probing it with an AI model. But a pretty big name on the field is throwing a little bit of cold water on their work. Just a little bit. Reinhard Genzel, a Nobel laureate and an astrophysicist at the Max Planck Institute, expressed some skepticism regarding the team's use of AI, and the quality of the data they fed into the model. "I'm very sympathetic and interested in what they're doing," Genzel tol

Star Quakes and Monster Shock Waves

Like the simulation depicting how a neutron star cracks, this one also predicts the characteristics of the resulting flares astronomers might see through telescopes. In the fleeting moments when monster shock waves rip outward and a black hole pulsar forms, telescopes may be able to catch outbursts of radio waves or a combination of X-rays and gamma rays. In short, the simulations performed by Most and colleagues provide a deeper understanding of the physics driving some of the most energetic ev

Microsoft fixes first known zero-click attack on an AI agent

techspot.com Kishalaya Kundu 2025-09-17 04:48:00

TL;DR: Microsoft has patched a critical zero-click vulnerability in Copilot that allowed remote attackers to automatically exfiltrate sensitive user data simply by sending an email. Dubbed "EchoLeak," the security flaw is being described by cybersecurity researchers as the first known zero-click attack targeting an AI assistant. EchoLeak affected Microsoft 365 Copilot, the AI assistant integrated across several Office applications, including Word, Excel, Outlook, PowerPoint, and Teams. Accordin

Zero-click AI data leak flaw uncovered in Microsoft 365 Copilot

bleepingcomputer.com Unknown 2025-09-18 06:48:50

A new attack dubbed 'EchoLeak' is the first known zero-click AI vulnerability that enables attackers to exfiltrate sensitive data from Microsoft 365 Copilot from a user's context without interaction. The attack was devised by Aim Labs researchers in January 2025, who reported their findings to Microsoft. The tech giant assigned the CVE-2025-32711 identifier to the information disclosure flaw, rating it critical, and fixed it server-side in May, so no user action is required. Also, Microsoft no

Astronomers Are Using Artificial Intelligence to Unlock the Secrets of Black Holes

wired.com Jorge Garay 2025-09-17 22:30:00

There may not yet be telescopes capable of unlocking all the secrets of supermassive black holes, but AI is now on the case. Recently, an international team of astronomers successfully trained a neural network with millions of black hole simulations to allow it to interpret fuzzy data captured from these enigmatic space objects in real life. Of the various methods for investigating a black hole, the Event Horizon Telescope is the most famous. The EHT isn’t a single instrument but rather a numbe
