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."

New Delhi, Feb 16: Aam Aadmi Party (AAP) national convener Arvind Kejriwal was on Sunday sworn-in as the Chief Minister of Delhi for the third time in a row at Ramlila Maidan here, after his party registered a massive victory in the recently concluded Delhi Assembly polls.

Kejriwal was administered the oath of office and secrecy by Delhi Lieutenant Governor Anil Baijal.

The sprawling Ramlila Maidan reverberated with sounds of thousands of people cheering for the AAP leader.

Kejriwal who received a hero's welcome here had extended an invitation to the people of Delhi urging them to attend the swearing-in ceremony to witness "the son of Delhi" taking oath today.

The AAP nearly repeated its 2015 performance in the elections, sweeping the Assembly polls winning 62 seats in the 70-member Assembly, in the face of a high-voltage campaign by the BJP, which fielded a battery of Union Ministers and Chief Ministers in its electioneering spearheaded by Home Minister Amit Shah.

Dhaka, Jan 3: Bangladesh's paramilitary force chief said on Thursday that a total of 445 Bangladeshi nationals returned from India in last two months following the publication of the National Register of Citizens (NRC) by the Indian government.

Border Guard Bangladesh (BGB) Director General Maj Gen Md Shafeenul Islam disclosed the figure during a press briefing here.

"About 1,000 people were arrested in 2019 for illegal border crossings from India to Bangladesh, with 445 of them returning home in November and December," he said.

After verifying their identities through local representatives, BGB came to know that all the intruders are Bangladeshis, Islam said, adding that 253 cases were lodged against them for illegal trespass, while initial investigations found that at least three of them were human traffickers.

The BGB Director said the trespassing did not create any tension between the border forces of Bangladesh and India.

Last week, Islam visited India where he said that the creation of the NRC is completely an "internal affair" of India and the cooperation between the border guarding forces of the two countries is very good.

He said the BGB will continue to do its work of preventing illegal border crossings as per its mandate.

A BGB delegation, led by Islam, was on a bilateral visit to India to hold DG-level border talks with its counterparts, the Border Security Force (BSF).

The talks took place from December 26-29, during which a host of issues related to cross-border smuggling and activities of criminals and others along the 4,096-km-long front were discussed.

Responding to a question, Islam said, "No discussion was held at the conference over the (NRC) issue".

He said during the five-day talks held in New Delhi, the BGB demanded that the BSF should take effective steps to prevent killings of Bangladeshis on frontiers as casualty figures sharply rose in 2019.

"The number of border killings in 2019 was highest in the last four years. As per our calculation, the number of such unexpected deaths was 35," the BGB chief said.

However, the BSF estimate of the casualty figure is much lower than our calculation, he said.

Islam said the BSF is following the policy of maintaining maximum restraint and minimal use of force even after being attacked by "armed border offenders".

A statement issued by the BSF last month in New Delhi after the conclusion of the DG-level talks said, "On the concern of the BGB regarding the death of Bangladeshi nationals on borders, it was informed to them that a non-lethal weapon policy is strictly followed by BSF personnel on borders.

"Firing is resorted to only in self-defence, when BSF patrols are gheraoed and attacked by ‘dah’ (a sharp-edged weapon) etc. It was specified that the BSF does not discriminate between criminals based on nationality," it said.
