Washington, Apr 10: Scientists released the much-awaited first direct image of a massive black hole at the centre of Messier 87, a galaxy which is about 54 million light-years away, at the National Press Club here on Wednesday. 

The image has been taken by the Event Horizon Telescope (EHT), which is a network of 10 radio telescopes spread across the planet, according to The Washington Post. The telescope functioned as if it is a single receiver, tuned to high-frequency radio waves, to take the image. 

The picture - released at six simultaneous news conferences on Wednesday - shows the event horizon, which is the boundary between light and dark around a black hole. A doughnut-like body can be seen in the portrait, which scientists say is the dark silhouette of the black hole against the hot, glowing material that surrounds it. 

"We are able to image one more object in the universe that ... at one point people thought could not be possible. It hits that human explorer spirit. We got another look into the unknown," Feryal Ozel, a member of the science council for the EHT said, calling the occasion her career's highlight.
 
The shape of the black hole matches what theorists had predicted ever since they started wrestling with Albert Einstein, General Theory of Relatively over a hundred years ago, reports The Washington Post. 

The European Commission hailed the occasion as a "paradigm shift" adding, "This major scientific achievement marks a paradigm shift in our understanding of black holes, confirms the predictions of Albert Einstein's General Theory of Relativity and opens up new lines of enquiry into our universe."

Kabul, May 11: Four back-to-back roadside bombs exploded in a northern district of Afghanistan's capital Kabul on Monday, wounding four civilians including a child, police said. Kabul police spokesman Ferdaws Faramarz said a clearance team was at the site of the attacks.

Militants have carried out several roadside bombings and rocket attacks in Kabul and other parts of the country in recent weeks, but Monday's four consecutive explosions appeared to be the first coordinated effort for some months.

The Taliban has not carried out any large attacks in the city since they signed a landmark withdrawal deal with the US in February, meant to pave the way for peace in the country. No group has claimed the attacks. The explosions come as authorities are trying to impose a lockdown in the capital to curb the spread of coronavirus in the country.

Guwahati, Feb 13: Hours after Assam's updated citizenship data disappeared from the website 'nrcassam.nic.in', an FIR was filed against a former NRC official for allegedly failing to submit the password to the sensitive document before quitting her job.

Talking to news agency on Thursday, NRC state coordinator Hitesh Dev Sarma said the complaint against former NRC project officer was filed under Official Secrets Act in Paltan Bazar police station here, as she "did not provide the password to the document, despite written reminders".

"She failed to surrender the password even after tendering her resignation on November 11 last year. She was a contractual employee and no longer authorised to hold the password, after quitting her job. An FIR has been filed against the former NRC project officer on Wednesday for violating the Official Secrets Act," he said.

Sarma also stated that the NRC office had written to her on several occasions for submitting the password, but did not get any response.

"We knew (she had resigned) and, therefore, sent several letters to her for handing over the password. But as she did not respond all these months, we filed a complaint against her yesterday for violating the Official Secrets Act.

"We must know if she has tampered with the sensitive information, after resigning," he added. The NRC state coordinator, however, refuted allegations of "malafide intent" involved in the matter.

"...this (cloud service provided by IT major Wipro) was not renewed by the earlier coordinator. So, the data went offline from December 15 last year. I assumed charge only on December 24," Sarma, who had gone on leave for a weeks after being appointed as the NRC state coordinator, clarified.

He also said that the state coordination committee had discussed the issue in its meeting on January 30 and wrote to Wipro during the first week of February.

"Once Wipro makes the data live, it will be available to the public. We hope that people will be able to access it in the next 2-3 days," Sarma claimed.

Reacting to the development, Wipro had said: "The IT Services Contract was not renewed by the authorities upon its expiry in October, 2019. However, as a gesture of goodwill, the company continued to pay the hosting service fee until January-end, 2020."

In another FIR filed with state criminal investigation department on Wednesday, NGO Assam Public Works (APW) alleged that former NRC Assam coordinator Prateek Hajela tampered with the final NRC list - published on August 31, 2019.

APW member Rajib Deka, in his complaint, accused Hajela of disobeying orders and directions of the Supreme Court, forgery of public register and committed offences under cyber laws for altering or changing public records by misusing his powers and position.

The NGO also said that after publication of the final list, several social networks and sections of the media had reported anomalies, insisting that many 'doubtful' persons were able to insert their names in the final list.

The Centre on Wednesday asserted that NRC data in Assam was safe even though some technical issues have been detected, which would be resolved soon.

Senior journalist-cum-RTI activist Saket Gokhale had sent an application to the NIC, the IT wing of the government, seeking a copy of the contract with Wipro.

"The Assam NRC data suddenly vanishing from the website (& the lack of data security) is incredibly shady. I've filed an RTI with the NIC specifically asking about details of the contract with Wipro, name of the cloud service provider, & all contracts signed for hosting this," he tweeted, while attaching a copy of the RTI application.

Leader of the Opposition in Assam Assembly and Congress leader Debabrata Saikia has also written to the Registrar General of India, requesting him to look into the fiasco urgently.

"It is a mystery as to why the online data should vanish all of a sudden, especially as the process to file appeals was yet to begin, all because of the go-slow attitude adopted by the NRC Authority. There is, therefore, ample scope to suspect that disappearance of online data is a malafide act," he had insisted.
