Things to know about the new black hole photo

The phrase “black hole” was coined because black holes suck all light in, leaving nothing optical to observe. Yet humans have managed to take photos of these mystic supermassive space objects lightyears away.

As we appreciate the first photo of a black hole on the Milky Way, let’s check out some interesting things you may want to know.

Why can’t we ‘see’ black holes?

Humans see things through the reflection of visible light. We cannot visually see a black hole because it is so massive that it pulls light in with gravity – a bit like how Earth pulls us onto its surface.

How did scientists photograph the black hole then?

Scientists are humans and they cannot see black holes either. But they can use advanced technologies to monitor objects around the black hole to learn about it.

In addition to pulling things toward itself, a black hole can also significantly twist the space around it. This also provides data for scientists to visualize it.

For the photo published on Thursday, scientists from many countries around the globe used observatories to form a virtual, Earth-sized telescope to capture the image.

Is this the first ever photo of a black hole?

No. This is only the first photo of a black hole that is located along the Milky Way named Sagittarius A* (Sgr A*).

The first photo of a black hole was revealed back in 2019 by the same project, called Event Horizon Telescope (EHT) Collaboration. The EHT is the giant telescope mentioned above.

UN adopts first global artificial intelligence resolution to ensure AI is safe

The United Nations General Assembly unanimously adopted the first global resolution on artificial intelligence on Thursday, encouraging countries to safeguard human rights, protect personal data, and monitor AI for risks.

The nonbinding resolution, proposed by the United States and co-sponsored by China along with over 120 other nations, also advocates for the strengthening of privacy policies.

“Today, all 193 members of the United Nations General Assembly have spoken in one voice, and together, chosen to govern artificial intelligence rather than let it govern us,” U.S. Ambassador to the United Nations Linda Thomas-Greenfield said.

The resolution is the latest in a series of initiatives – few of which carry significant enforceability – by governments around the world to shape AI’s development amid fears it could disrupt democratic processes, turbocharge fraud, or lead to dramatic job losses, among other harms.

“The improper or malicious design, development, deployment and use of artificial intelligence systems … pose risks that could … undercut the protection, promotion and enjoyment of human rights and fundamental freedoms,” the measure states.

In November, the U.S., Britain and more than a dozen other countries unveiled the first detailed international agreement on how to keep artificial intelligence safe from rogue actors, pushing for companies to create AI systems that are “secure by design.”

Europe is ahead of the United States, with EU lawmakers adopting a provisional agreement this month to oversee the technology. The Biden administration has been pressing lawmakers for AI regulation, but a polarized U.S. Congress has made little headway. In the meantime, the White House sought to reduce AI risks to consumers, workers, and minorities while also bolstering national security with a new executive order in October.

The resolution aims to close the digital divide between rich developed countries and poorer developing countries to ensure that all are included in discussions on AI. It also aims to ensure that developing countries have the technology and capabilities to take advantage of AI’s benefits, including detecting diseases, predicting floods, helping farmers, and training the next generation of workers.

The resolution recognizes the rapid acceleration of AI development and use and stresses “the urgency of achieving global consensus on safe, secure and trustworthy artificial intelligence systems.”

It also acknowledges that “the governance of artificial intelligence systems is an evolving area” that requires further discussions on possible governance approaches and emphasizes that innovation and regulation are mutually reinforcing – not mutually exclusive.

Beijing has consistently ranked first in the global science city rankings for eight consecutive years, as measured by the Nature Index, according to Yin Yong, deputy secretary of the Communist Party of China (CPC) Beijing Municipal Committee and mayor of Beijing.

Nature Index tracks the authorship of articles in prestigious research journals and Beijing’s ranking has shown that the city remains the top science city in the world.

On Tuesday, China’s State Council Information Office held a press conference on leveraging Beijing’s strategic role as the national capital, initiating a new chapter in high-quality development. Yin made the remarks while he answered questions from the media at the press conference.

Yin also introduced the capital’s achievement in seeking scientific and technological innovation and attracting high-level talent in science and technology.

Beijing has 92 colleges and universities, and more than 1,000 research institutes and its numbers of national laboratories and large scientific installations are ranked first in the country.

Beijing’s investment in research and development has also been among the largest in the country. Every 10,000 people in Beijing hold an average of over 262 invention patents, ranking first in China.

The capital has a large talent pool with more than 550,000 scientific researchers. In the field of artificial intelligence, for instance, Beijing’s top talent accounts for about 43 percent of the country’s total.

An average of 337 technology-based enterprises are established in Beijing every day, and the number of national high-tech enterprises and unicorn enterprises rank first among all cities in the country.

KHON KAEN, Thailand, March 5 (Xinhua) — A hydro-floating solar project jointly built by Chinese and Thai companies started commercial operation on Tuesday to support Thailand’s development of clean energy.

The Ubolratana Dam hydro-floating solar hybrid power plant, located in Thailand’s northeastern Khon Kaen province, integrates floating solar panels, clean hydropower, high-efficiency energy storage systems, and smart energy management systems, according to Dongfang Electric International Corporation, one of the world’s largest manufacturers of power-generating equipment that built the project with its Thai partner.

Jiraporn Sirikum, deputy governor of the Electricity Generating Authority of Thailand (EGAT), said building floating solar hybrid power plants is an important step toward the clean energy production and power stability of Thailand, praising the Chinese and the Thai companies for being able to deliver the project ahead of schedule.

“This showed a serious commitment to promoting clean energy in Thailand. We sincerely hope that the floating solar will help to promote clean energy for the community economy and local society,” Jiraporn told a commercial operation launching ceremony.

Liu Hongmei, Chinese Consul General in Khon Kaen, said she believed that the project’s commercial operation would bring greater well-being to the people of Northeast Thailand and mark a new milestone for Chinese enterprise investment in the region.

The Ubolratana Dam hydro-floating solar hybrid power plant is its second such hydro-floating solar project, said EGAT, which aims to build more such projects nationwide to promote clean energy.
