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.”

WhatsApp launches bulk channel management functionality

Published

By

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

By

In an effort to better prepare young people for opportunities in the quickly changing technology sector, the government has launched a new ICT training portal.

To allow graduates to work with IT companies, Huawei and the Ministry of IT have struck an agreement. This program will give participants hands-on exposure to cutting-edge technology, including cybersecurity and artificial intelligence (AI).

There is now a training program that offers three-year internships to graduates. Huawei has also stated that it is dedicated to helping with training initiatives and contemporary technology.

In order to strengthen technical training, Huawei signed an MOU with COMSATS University Islamabad, further demonstrating its support.

Plans call for establishing training facilities in Karachi and growing the initiative across the country.

These projects funded by the Special Investment Facilitation Council are key to revitalizing Pakistan’s economy and fostering growth in the IT sector.
