Researchers found what they believe is a 2,000-year-old map of the starsThe star catalog was made by ancient Greek astronomer Hipparchus around 162 and 127 BCE, 1,400 years before the telescope. What is nuclear fusion?

Harnessing the power of the sun in the quest for clean energyScientists, governments, and companies from around the world are increasingly investing in a potential source of energy that could provide unlimited, clean power to everyone on Earth : nuclear fusion. Not this again, but I read some stuff there are indeed some actual progress but if that dog would hunt, yeah better be quick. Clock is running.

See Also A massive star at the end of its life The vision came from the constellation Sagitta where a massive star at the end of its life exploded and collapsed into a black hole, ejecting a jet of light into space more than 2 billion years ago. Or, if you prefer, 20 billion trillion kilometers away from us, a decent fraction of the size of the observable universe. The burst of light it produced was so intense that it blinded the detectors of some telescopes, told the SCMP HEBS chief scientist Xiong Shaolin, who is from the Institute of High Energy Physics at the Chinese Academy of Sciences in Beijing.

Normally FIFA World Cup tournaments are held during the summer in the Northern Hemisphere and come after the end of the football season in Europe. Astronomers named the event GRB 221009A and they report that it was at least 10 times brighter than previous gamma-ray bursts.

This one was so close, cosmically speaking, that it was detected by a fleet of observatories both on and above the Earth, and is already yielding a trove of scientific treasure. The scientists speculate that it also released the same amount of energy that would take thousands of suns their entire lifetimes to generate. When charged particles travel along curved paths at speeds near that of light — or relativistic speeds — they generate an intense form of light called synchrotron radiation.

The event produced a maximum energy level that broke the previous record detected by the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes in Spain in 2019. Despite that, this gamma-ray burst poses no danger to us. It will also be the first time that an Arab country hosts a World Cup.

The event was 10 times more powerful than its predecessor. This was especially impressive since high-energy particles are usually absorbed by starlight on their way to Earth making them impossible to identify. Gamma-ray bursts, or GRBs, are intense blasts of gamma rays—the highest-energy form of light—that typically last from a fraction of a second to a few minutes in length.

China’s Large High Altitude Air Shower Observatory (Lhaaso), located on the Tibetan Plateau in Sichuan province, was able to confirm that the event was indeed a powerful gamma-ray burst.

Lhaaso chief scientist Cao Zhen called the event “totally unexpected and extraordinary.

Over 1,700 have been observed since then."This result is teaching us about a fundamental aspect of the debris from this exploded star — the behavior of its magnetic fields. " Most Popular Razmik Mirzoyan at the Max Planck Institute of Physics in Munich, Germany, further stated that Lhaaso’s input was crucial to spotting the cosmic explosion. “Lhaaso’s wide field of view, combined with its sensitivity, makes it a very powerful detector for measuring diverse classes of cosmic and gamma rays at very high energies,” he said.

Even then it was difficult, as each GRB has idiosyncrasies, making them complicated to understand as a group. Brazil last took the World Cup title in South Korea and Japan 2002, after beating Germany 2-0 in Yokohama.

An extremely rare event Shaolin added that the event was indeed very rare. “Actually it’s one of the closest gamma-ray bursts that has ever happened – something that only occurs every few decades or even once a century,” he said. Short-duration bursts—generally a few seconds long at most—come from two superdense neutron stars colliding and blasting out fierce energy, whereas long-duration ones—lasting several minutes—come from massive stars exploding at the ends of their lives.

The next steps now are for astronomers around the world to work together to better understand GRB 221009A, using data from both the explosion and the afterglow that followed it. At the 2018 World Cup in Russia, Les Bleus were crowned the world champions over their 4-2 win against Croatia, with Griezmann, Pogba and Mbappe among the scorers in Moscow.

Small amounts of polarization indicate that the magnetic fields are close to the leading shockwaves, or shockfront. . A swirling disk of material that wasn’t immediately swallowed by the black hole rapidly forms around it, funneling twin beams of intense energy out into space, one pointing up and the other down, away from the disk.

“In an event like this, a supernova is expected to show up about two weeks after the explosion,” said Bing Zhang from the University of Nevada, Las Vegas. The event highlights the that can be made when scientists worldwide join forces and work toward a common goal. The energy in gamma-ray bursts is almost incomprehensible: In a few seconds they can emit as much energy as the sun will over its entire 12-billion-year lifespan.
