‘Ghost particle’ seen in 2019 was followed by a star stripped by a neutrino observatory in Antarctica- Technology News, Firstpost

Scientists found a ghost grain to a star stripped as it went too close to a black hole. The torn-off star sent a full-energy neutrino that was released into space at the violent event. In October 2019, the Earth was in the path of these cosmic bullets, which move at almost the speed of light. Surprisingly, one neutrino hit the ice right next to a highly sensitive neutrino detector under the South Pole. Researchers at the observatory, called the IceCube observatory neutrino, saw the full-energy neutrino burned out across the cosmos, traveling more than 700 million light-years.

In a new study published this week in Astronomy of nature, scientists said they were tracing the origin of the subatomic bullet back to the destruction of a star as it was torn by a black hole, about 700 million years ago. The black hole is as big as 30 million suns, and gravity is so powerful that it can tear stars to pieces.

Robert Stein, a scientist at Deutsches Elektronen-Synchrotron’s acceleration and research center, said that when the gravitational force of the black hole comes very close to an object, the black hole pulls a side closer to the star more firmly than the other side of the star, which is also known as the tidal force. As the star approaches, the stretch becomes more intense, eventually tearing the star to pieces. This is the event of a tidal riot. This wonder is the only thing that follows a tidal wave on Earth. Fortunately, the moon is not pulling hard enough to cut the Earth into pieces.

Followed by the crash, half of the debris was removed flying into space, and the other half remained on a disk around the black hole that circulated like water around the drain, which begins to fade. getting hot and shining.

The Zwicky Movement Facility in California saw the call from Earth in April 2019 and in October the South Pole IceCube detector identified a very energetic neutrino that broke into the ice in Antarctica with 10 times the energy of any gravitational accelerator. the Earth that came from the same tidal disturbance event.

Scientists captured the event using a combination of different telescopes, looking at the ultraviolet, optical and radio evidence of the peeling to gather more details about it.
