Neutrino physics -- What are the project goals for the Jiangman underground observatory (JUNO)?

Jiangman underground observatory (JUNO) is a setup at china which is used for detection of neutrino and their oscillation so far as I know. What is the basic goal of making this setup, Are they interested to observe the effect of neutrino on earth i.e neutrino may rise the temp of earth or some thing else please clear if some one know about that ?. Thanks

Google is your friend

Neutrinos are part of Nature and physics seeks to predict and explain how Nature behaves. Do some googling of the solar neutrino problem. The problem was solved by studying the way neutrinos oscillate.
