Deep within a mountain in China, scientists are constructing an enormous sphere designed to capture elusive particles known as neutrinos. These particles are incredibly small and can pass through almost anything, including the entire Earth! But why are scientists so eager to catch neutrinos?
Neutrinos hold valuable information about the beginning of the universe, the Sun, and even the inner workings of our planet. By studying these particles, researchers can gain insights into fundamental processes that govern the cosmos.
The massive sphere is filled with a special liquid that emits light when neutrinos pass through it. Thousands of sensors are installed to detect these fleeting flashes of light, enabling scientists to learn more about the neutrinos' properties and behaviors.
The Jiangmen Underground Neutrino Observatory (JUNO) is located in Guangdong, China. It features a colossal, 12-story high water pool that contains a spherical detector. The primary objectives of JUNO include:
The India-based Neutrino Observatory (INO) is situated in Theni, Tamil Nadu, India. Although smaller than JUNO, INO is still a significant detector. Its main goals are:
Both JUNO and INO represent pivotal scientific ventures that will enhance our understanding of neutrinos and the universe as a whole. They are expected to yield groundbreaking discoveries in the field of particle physics.
Q1. Why is the sphere built underground?
Answer: It is constructed underground to block cosmic particles that might interfere with the experiment's results.
Q2. What can we learn from neutrinos?
Answer: Neutrinos provide insights into the early universe, solar processes, and the Earth's internal structure.
Q3. How does the sphere catch neutrinos?
Answer: The sphere's special liquid lights up when neutrinos pass through, and sensors detect these light flashes.
Q4. What is special about this project?
Answer: JUNO is one of the largest neutrino detectors globally, poised to deepen our understanding of these mysterious particles.
Q5. Is there a similar project in India?
