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.”
As news broke that Donald Trump’s social media company was in negotiations to acquire cryptocurrency trading platform Bakkt (BKKT.N), Bitcoin surged to a record high above $94,000, adding to optimism that the next Trump administration would be cryptocurrency-friendly.
This year, Bitcoin, the largest and most well-known cryptocurrency in the world, has more than doubled in value. Just before the close of the previous session, it reached a record high of $94,078 before closing at $92,104 in Asian hours on Wednesday.
According to the Financial Times, which cited two persons with knowledge, NYSE-owner Intercontinental Exchange (ICE.N) is supporting Trump Media and Technology Group (DJT.O), opens new tab, which runs Truth Social, in its pursuit of an all-stock purchase of Bakkt.
In addition to traders taking advantage of the first day of options trading on the Nasdaq over BlackRock’s Bitcoin ETF (IBIT.O), Tony Sycamore, market analyst at IG, stated that the Trump deal chatter had helped push bitcoin to a record high.
As traders hoped that President-elect Trump’s pledged support for digital assets would result in a less stringent regulatory framework and give bitcoin a boost after a sluggish few months, cryptocurrencies have surged since the U.S. election on November 5.
According to data and analytics aggregator CoinGecko, the global cryptocurrency market is now worth over $3 trillion, a new high, due to the growing excitement.
Australian online broker Pepperstone’s head of research, Chris Weston, stated that there is genuine underlying purchasing pressure on bitcoin and that “another kick higher should bring in a fresh chase from those who like to buy what’s strong.”
Speaking at the Senate Standing Committee on IT meeting in Islamabad, which was presided over by Palwasha Khan, was the PTA chief.
The continuous regulation of Virtual Private Networks (VPNs) in Pakistan was the main topic of discussion. The committee called for the next meeting and voiced concerns about the Minister of State for IT’s absence for the third consecutive session.
“We have spent the last two years developing VPN legislation. Uninterrupted internet connection is guaranteed by registered VPNs without sacrificing privacy, according to the PTA chairman.
During the session, Senator Muhammad Humayun criticized the measures, saying, “Shutting down platforms like X (formerly Twitter) is jeopardizing the entire IT industry and impacting the livelihoods of over 2.5 million individuals in Pakistan.”
He opposed laws that would hurt independent contractors and small companies.
Although the PTA promised that registered VPNs would not experience internet outages, committee members wanted to know the exact legal foundation for these regulations. Senator Kamran Murtaza asked for documents that detailed the requirements for registration.
“If VPN services are abruptly halted, there will be a major backlash,” Senator Afnan Ullah said. While pointing out that Pakistan’s IT exports had increased by 20% in the previous year, he emphasised that the sector was still lagging behind India.
Concerns over the viability of the existing VPN whitelist method were voiced by the committee. While IT officials admitted that more than 1 million freelancers in Pakistan rely significantly on VPNs for their business, Senator Humayun pointed out that the laws should be more beneficial than harmful.
The National Computer Emergency Response Team (CERT) has released a security advisory concerning the increasing utilization of artificial intelligence (AI) chatbots, emphasizing potential hazards related to the exposing of private data.
The recommendation recognizes that AI chatbots, like ChatGPT, have gained significant popularity for personal and professional duties owing to their capacity to improve productivity and engagement. Nonetheless, the CERT cautions that these AI systems frequently retain sensitive information, so posing a danger of data breaches.
Engagements with AI chatbots may encompass sensitive information, such as corporate strategy, personal dialogues, or confidential correspondence, which could be compromised if inadequately safeguarded. The warning emphasizes the necessity for a comprehensive cybersecurity framework to alleviate concerns associated with AI chatbot utilization.
Users are advised against inputting critical information into AI chatbots and are encouraged to deactivate any chat-saving functionalities to mitigate the danger of unwanted data access. The CERT additionally advises performing routine system security checks and employing monitoring tools to identify any anomalous behavior from AI chatbots.
Organizations are urged to adopt rigorous security protocols to safeguard against possible data breaches resulting from AI-driven interactions.
