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.”

VPNs, X, and Slow Internet Services Are Still Blocked in Pakistan

Published

By

Users are reporting poor performance on numerous social media sites due to widespread slowdowns in internet access. Furthermore, X (previously Twitter) has been inaccessible for the past six days, despite the Sindh High Court’s directive to allow access. In the meantime, Pakistan is blocking VPN services.

X Remains Unblockable

On February 17, 2024, the Pakistani government first prohibited access to X when it was discovered that Rawalpindi’s Commissioner had rigged election results. The block is still in effect, even though there has been no official announcement or explanation for it. Despite the Supreme Court’s decision to lift the prohibition, the administration has not yet disclosed any plans for reinstatement. Furthermore, officials are giving media outlets conflicting information about the limitations.

Blocked VPN Services

Virtual private network (VPN) services are being widely blocked nationwide, which exacerbates the problem. Apart from limiting accessibility to X, the government has initiated the banning of prominent VPN providers, impeding users’ capacity to establish connections with any server.

sluggish internet access

There is a noticeable slowdown in internet speeds and a decline in performance across Pakistan. The problem hasn’t been acknowledged by the Pakistan Telecommunications Authority (PTA), nevertheless. Even though internet service providers (ISPs) insist there aren’t any outages, consumers on social media sites are nonetheless complaining about poor access.

Adding to the current difficulties with online connectivity, internet users in Pakistan experienced yet another disturbance when attempting to use the services of social media site X, formerly known as Twitter.

Users from Islamabad and other regions of the nation were unable to use the site for several hours since the service was down.

The Pakistan Telecommunication Authority (PTA), which is becoming increasingly concerned about the frequent outages, has not made an official remark about the matter.

The suggestion was made at the meeting of the ECP, which was convened to examine the state of law and order in Khyber Pakhtunkhwa and Balochistan.

According to those with knowledge of the situation, there was a suggestion to cut back on mobile and internet service in vulnerable sections of the nation in time for the general elections in 2024.

The election candidates’ security was also a topic of discussion during the conference, and CEC Sikandar Sultan Raja voiced his worries about the rise in attacks on political gatherings in Khyber Pakhtunkhwa and Balochistan.
