Star’s extreme proximity to Sagittarius A* means it could open new window onto black hole’s fundamental properties Astronomers have detected the fastest known star in the Milky Way, hurtling around the supermassive black hole at the heart of the galaxy. The star, called S301, travels at about 25,000km (15,500 miles) per second, 100,000 times faster than a commercial plane. It is also the closest known star to the Milky Way’s central black hole, Sagittarius A*, approaching it around the distance of Saturn to the Sun.

All five systems tested were found to be ‘highly vulnerable’ to attempts to elicit harmful responses
Guardrails to prevent artificial intelligence models behind chatbots from issuing illegal, toxic or explicit responses can be bypassed with simple techniques, UK government researchers have found.
The UK’s AI Safety Institute (AISI) said systems it had tested were “highly vulnerable” to jailbreaks, a term for text prompts designed to elicit a response that a model is supposedly trained to avoid issuing.
