Astronomers have captured an image from deep space which shows a jet material coming out from a black hole and entering into a space between the galaxies.
The released image of a black hole — located at the centre of the galaxy Messier 87 (M87) — would enable scientists to determine the behaviour of black holes.
Supermassive black holes are mysterious objects, located at the centre of a space which are gravitationally so powerful that nothing can escape from them not even light. It is still unknown what is inside the black hole or what happens when something goes inside a black hole.
Many supermassive black holes emit powerful light jets that are extremely bright.
Dr Ru-Sen Lu, the lead author of the Shanghai Astronomical Observatory said: “We know that jets are ejected from the region surrounding black holes, but we still do not fully understand how this actually happens.”
“To study this directly we need to observe the origin of the jet as close as possible to the black hole,” said Dr Lu.
The observation was carried out with the help of telescopes from the Global Millimetre VLBI Array (GMVA), the Atacama Large Millimeter/submillimeter Array (ALMA) and the Greenland Telescope (GLT), in 2018.
The focus object in space is galaxy M87 which is 55m light years away. This galaxy hosts a black hole which is 6.5bn times huge than the Sun.
According to scientists, the emitting jets from supermassive black holes are powered by the rotation of the black hole. But they do not yet know what causes them.
The captured image was published in the journal Nature showing the material interacting with matter, spinning around a supermassive black hole, however, the picture does not show the point of origin.
Dr Kazunori Akiyama of MIT’s Haystack Observatory, said: “This is the first image where we are able to pin down where the ring is, relative to the powerful jet escaping out of the central black hole.”
Dr Akiyama, who is also the developer of the imaging software used to visualise the black hole, said: “Now we can start to address questions such as how particles are accelerated and heated, and many other mysteries around the black hole, more deeply.”
An astrophysicist Dr Ziri Younsi at University College London, who was not involved in the process, explained the image as “really exciting”.
“It’s another important piece of the story of how black holes power jets.”
The New York-based cybersecurity firm Wiz has discovered a cache of sensitive data from the Chinese artificial intelligence business DeepSeek that was mistakenly exposed to the public internet.
In a blog post released on Wednesday, Wiz reported that examinations of DeepSeek’s infrastructure revealed that the company had inadvertently exposed over a million lines of unencrypted data. The materials were digital software keys and chat logs that seemingly documented prompts transmitted from consumers to the company’s complimentary AI assistant.
The chief technical officer of Wiz stated that DeepSeek promptly safeguarded the data following the notice from his organisation.
“It was removed in under an hour,” stated Ami Luttwak. “However, this was exceedingly easy to locate, leading us to believe we are not the sole discoverers.”
DeepSeek did not promptly respond to a request for comment.
DeepSeek’s rapid success after the introduction of its AI helper has exhilarated China and incited concern in America. The Chinese company’s evident capacity to rival OpenAI’s skills at a significantly reduced cost has raised concerns regarding the viability of the business models and profit margins of U.S. AI behemoths like Nvidia and Microsoft.
By Monday, it surpassed the U.S. competitor ChatGPT in downloads from Apple’s App Store, prompting a worldwide decline in technology stocks.
WhatsApp has initiated testing of a bulk channel administration feature on iOS for select beta users, enabling the simultaneous selection of many channels, hence enhancing the efficiency of managing following channels.
This essential update enables users to perform bulk activities, including muting many channels simultaneously, designating them as read, and altering notifications. If the chosen channels are muted, users will now have the option to activate notifications. Users can swiftly silence unmuted channels in one action.
Additionally, this feature enables users to unfollow many channels simultaneously, thereby optimizing the process of decluttering their channel list. This change is particularly beneficial for users that oversee numerous subscriptions, as reported by WABetaInfo.
Previously, users were required to manage each channel individually, rendering tasks such as muting or designating channels as read laborious and time-consuming.
The functionality provides enhanced flexibility and control over channel subscriptions, enabling users to efficiently manage notifications. The solution streamlines laborious operations for consumers who subscribe to numerous channels, hence enhancing their entire experience.
Accessibility The bulk management feature is presently accessible exclusively to a limited number of beta testers who installed the latest WhatsApp beta for iOS using the TestFlight application. WhatsApp, owned by Meta, plans to expand the feature’s availability to a larger user base in the next weeks.
This update demonstrates WhatsApp’s dedication to enhancing user experience by offering a clear and efficient method for managing channels and notifications.
Even after two weeks, the global submarine cable AAA-1 problem that was discovered on January 2 near Qatar has not been fixed, causing sluggish internet connection in several Pakistani towns.
According to a representative for Pakistan Telecommunication Company Limited (PTCL), the issue has affected customers’ capacity to effectively access social media applications and browse the online. Even with initiatives to fix the problem, social networking sites still lag during busy times.
Internet traffic has been redirected via alternate channels to lessen the impact, and more capacity has been set up to stabilize the service.
The PTCL representative promised that “Internet service across the country is operating normally, and there will be no issues with web browsing,” noting that social media applications’ lag is common during
