Ghost particle of Sun’s Fusion cycle discoveredDate: 08 December 2020 Tags: Miscellaneous
A hyper-sensitive instrument in Italy has succeeded at the task of detecting CNO neutrinos from our sun’s core.
Investigators report the first detections of this rare type of neutrinos, called “ghost particles” because they pass through most matter without leaving a trace.
The “ghost particle” detection confirms predictions from the 1930s that some of our sun’s energy is generated by a chain of reactions involving carbon, nitrogen and oxygen (CNO).
This reaction produces less than 1% of the sun’s energy, but it is thought to be the primary energy source in larger stars. This process releases two neutrinos as well as other subatomic particles and energy.
Neutrinos are exceedingly difficult to measure. Virtually all of these “ghost particles” pass through the entire planet without interacting with anything, forcing scientists to utilize very large and very carefully protected instruments to detect them.
A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.
Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect.
India-based Neutrino observatory
India-based Neutrino Observatory (INO) is a particle physics research project under construction to primarily study atmospheric neutrinos deep cave under INO Peak near Theni, Tamil Nadu.
This project is notable in that it is anticipated to provide a precise measurement of neutrino mixing parameters.
The project is a multi-institute collaboration and one of the biggest experimental particle physics projects undertaken in India.
