Scientists have recorded the strongest photons that have ever hit Earth



The Tibetan plateau is one of the most isolated areas in the world. At an average altitude of 5000 meters, it is separated from the world by the Himalayas in the south and the Taklamakan desert in the north. This makes it a great place to explore space, for example. For example, there is a research center dedicated to detecting subatomic space particles, where scientists have recently captured the strongest photons that have hit the Earth's surface in the history of observation, according to Technology Review reports.

A team of scientists who analyzed data collected by a research center for the detection of subatomic space particles in Tibet published a study in April describing the most powerful photon ever seen in our planet's history. The research center was built in 1990 and monitors subatomic particles for nearly three decades after the collision of high-energy space radiation with the top of our atmosphere.

So in Tibet, they have been monitoring high-energy photons for almost three decades. His shock to Earth's surface occurs quite frequently. The strongest energy so far has been in dozens of teraelétron volts (TeV 1012). But that was only true until recently. As the technology portal at MIT informs technologyreview.com, scientists have recorded for the first time in history a "swarm" of photons whose energy exceeds 100 TeV. Even the scientists were able to measure the energy of a photon, whose energy reached 500 TeV. In comparison, conventional visible light has only a few electron volts and the collision energy in a Hadron Large Accelerator reaches 14 TeV.

In addition, scientists have been able to estimate where the extreme-energy photons come from. They think they have traveled from the region of the Crab Nebula to the surface of the Earth, which is 6500 light years from Earth. High-energy photons appear to have broken out in the supernova – the explosion in which the nebula originated. It happened in 1054, when the nebula was visible for 23 days, even in daylight. The event was recorded by Chinese and Arab astronomers.

According to astrophysicist Petra Huentemeyer of MIT for ScienceNews, the discovery of Tibet brings "exciting moments." Scientists will now be interested in knowing exactly how high-energy photons emerge when they spread what they can say about the conditions in the middle of the nebulae and what the maximum photons can achieve in space. However, we are likely to wait a few years to answer these questions.
