Scientists capture image showing escaping jets from black hole

Published

on

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.

A view of the jet and shadow of M87’s black hole was released on April 26, 2023. — European Southern Observatory/R.-S. Lu (SHAO), E. Ros (MPIfR), S. Dagnello (NRAO/AUI/NSF)

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.”

The supermassive black hole imaged by the EHT is located in the centre of the elliptical galaxy M87, located about 55 million light-years from Earth. This image was captured by FORS2 on ESOs Very Large Telescope. The short linear feature near the centre of the image is a jet produced by the black hole. — NASA/File

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.”

63,000 Instagram accounts are deleted by Meta

The “Yahoo boys,” a group of Nigerian internet scammers, are well-known for their elaborate schemes, which include posing as needy individuals or promising phenomenal returns on investments from prominent Nigerian figures.

63,000 Instagram profiles, according to a statement by Meta, which also mentioned that 7,200 Facebook pages, groups, and accounts that offered advice on con artistry had been deleted.

The organisation also eliminated a smaller, more tightly-knit network of about 2,500 computers that belonged to a collective of about 20 people.

The prospect of compromising photos—fake or real—being released is used in sexual extortion, or “sextortion,” to coerce victims into paying to halt the abuse.

Meta notified the scammers’ attempts to the U.S. National Centre for Missing and Exploited Children, as most of the scammers’ attempts were unsuccessful and largely targeted adults, but there were also attempts made against kids.

The disruption of these networks was not new, according to Meta officials, who also disclosed the current operation in an effort to “raise awareness.”

Governments, particularly lawmakers in the US, where Meta is headquartered, have increased pressure on the social media behemoth to address allegations that its executives have disregarded data indicating that its services are harmful to children. As a result, the company has been under defensive fire in recent years.

One American senator charged Mark Zuckerberg, the CEO of Meta, and other prominent figures in the social media space earlier this year, saying they had “blood on their hands” for not doing enough to shield young people from the growing risks of sexual predatory content on their platforms.

Additionally, in an effort to raise awareness of these risks, the U.S. Surgeon General has advocated for social media apps to have a warning label attached.

A part of the national penal code that dealt with fraud ineffectively gave rise to the term “419 scams” for Nigerian con artists.

Online frauds have increased in number, with individuals responsible operating from wealthy neighbourhoods, college dorms, or impoverished suburban areas while the nation of more than 200 million people experiences increasing economic woes.

A few users, according to Meta, were giving advice on how to pull off scams.

It stated, “Among their attempts were links to photo collections that they could use to create fictitious accounts, as well as offers to sell scripts and instructions to deceive people with.”

Google abandons its plans to do rid of cookies in Chrome

Published

The significant change in course comes as a result of worries expressed by advertisers, who provide the majority of the company’s revenue, that their capacity to gather data for customised advertisements will be restricted due to the removal of cookies from the most widely used browser in the world, leaving them reliant on Google’s user databases.

Due to worries that Google’s proposal would stifle competition in the digital advertising market, the UK’s Competition and Markets Authority has also carefully examined the proposal.

“Rather than discontinuing third-party cookies, we would launch a fresh experience in Chrome that empowers individuals to make a knowledgeable decision that is applicable to all of their online browsing, and they could modify that decision whenever they choose,” stated Anthony Chavez, vice president of the Privacy Sandbox project, which is supported by Google, in a blog post.

A major objective of the Privacy Sandbox project, which was started in 2019 by Alphabet (GOOGL.O), opens new tab unit, is to phase out third-party cookies while simultaneously improving online privacy and boosting digital enterprises.

Though they can potentially be used for unauthorised monitoring, cookies are information packets that websites and advertisers use to identify specific online users and follow their browsing patterns.

Within the European Union, publishers are required to obtain explicit agreement from users before storing cookies, as per the General Data Protection Regulation (GDPR). Cookie deletion is another feature that most popular browsers offer.

While continuing to fund the Privacy Sandbox programme, Chavez stated that Google was collaborating on the new strategy with publishers, privacy organisations, and regulators like the UK’s Information Commissioner’s Office and CMA.

Many responded differently to the announcement.

Analyst Evelyn Mitchell-Wolf of eMarketer stated in a statement, “Advertising stakeholders won’t have to prepare to quit third-party cookies cold turkey.”

One example of how cookies can hurt consumers is when they display predatory advertisements that target specific demographics, according to Lena Cohen, a staff technologist at the Electronic Frontier Foundation. According to Cohen, Google’s choice to keep accepting third-party cookies is a direct result of their advertising-driven business model, even though other major browsers have been banning them for years.
