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."

Seoul, Jun 6: South Korea on Saturday reported 51 new cases of COVID-19, mostly in the densely populated capital region, as authorities scramble to stem transmissions among low-income workers who can't afford to stay home.

The figures announced by South Korea's Centers for Disease Control and Prevention brought national totals to 11,719 workers and 273 deaths.

At least 34 of the new coronavirus cases were linked to door-to-door sellers hired by Richway, a Seoul-based health product provider.

Vice Health Minister Kim Gang-lip said the spread of the virus among Richway sellers was particularly alarming as most of them are in their 60s and 70s. He called for officials to strengthen their efforts to find and examine workplaces vulnerable to infections.

More than 120 infections have also been linked to a massive warehouse operated by Coupang, a local e-commerce giant, which has been accused of failing to properly implement preventive measures and having employees work even when sick.

South Korea was reporting around 500 new cases per day in early March due to a massive outbreak surrounding the southern city of Daegu, before officials managed to stabilize the situation with aggressive tracking and testing.

But the recent resurgence of COVID-19 in the greater capital area, where about half of South Korea's 51 million people live, is now threatening to erase some of the country's hard-won gains. It has also led to second-guessing whether officials were too quick to ease social distancing and reopen schools.

Health authorities and hospital officials on Friday participated in a table-top exercise for sharing hospital capacities between Seoul and nearby cities and ensure swift transports of patients so that a spike of cases in one area doesn't overwhelm its hospital system.

Jul 3: China under President Xi Jinping has stepped up its "aggressive" foreign policy toward India and "resisted" efforts to clarify the Line of Actual Control that prevented a lasting peace from being realised, according to a report released by a US Congress appointed commission.

The armies of India and China have been locked in a bitter standoff at multiple locations in eastern Ladakh for the last seven weeks, and the tension escalated after 20 Indian soldiers were killed in a violent clash in the Galwan Valley on June 15.

“Under General Secretary of the Chinese Communist Party (CCP) Xi Jinping, Beijing has stepped up its aggressive foreign policy toward New Delhi. Since 2013, China has engaged in five major altercations with India along the Line of Actual Control (LAC),” said a brief issued by US-China Economic and Security Review Commission.

"Beijing and New Delhi have signed a series of agreements and committed to confidence-building measures to stabilise their border, but China has resisted efforts to clarify the LAC, preventing a lasting peace from being realised,” said the report and was prepared at the request of the Commission to support its deliberations.

Authored by Will Green, a Policy Analyst on the Security and Foreign Affairs Team at the Commission, the report says that the Chinese government is particularly fearful of India’s growing relationship with the United States and its allies and partners.

“The latest border clash is part of a broader pattern in which Beijing seeks to warn New Delhi against aligning with Washington,” it said.

After Xi assumed power in 2012, there was a significant increase in clashes, despite the fact that he met Prime Minister Narendra Modi several times and Beijing and New Delhi have agreed to a series of confidence-building mechanisms designed to mitigate tensions.

Prior to 2013, the last major border clash was in 1987. The 1950s and 1960s were a particularly tense period, culminating in 1962 with a war that left thousands of soldiers dead on both sides, according to the records of China's People's Liberation Army, the report said.

“The 2020 skirmish is in line with Beijing’s increasingly assertive foreign policy. The clash came as Beijing was aggressively pressing its other expansive sovereignty claims in the Indo-Pacific region, such as over Taiwan and in the South and East China seas,” it said.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Several weeks before the clash in the Galwan Valley, Chinese Defence Minister Wei Fenghe called on Beijing to “use fighting to promote stability” as the country’s external security environment worsened, a potential indication of China’s intent to proactively initiate military tensions with its neighbours to project an image of strength, the report said.

New Delhi, Jan 10: An IPS officer's thumb was bitten by a woman protester when he was pushing back agitators, who were trying to march towards the Rashtrapati Bhawan here on Thursday, police sources said.

The protesters had gathered after a call was given by JNU Students' Union president Aishe Ghosh to march towards President's House to demand the removal of University's Vice Chancellor, M Jagadesh Kumar.

Ingit Pratap Singh, a 2011 batch officer, who is currently posted as the additional deputy commissioner of the southwest district, was injured in the attack.

According to sources, Singh was trying to pull a male protester when the woman, in a bid to shield her friend, bit Singh's left thumb.
