The Chacaltaya Cosmic Physics Laboratory, located at 5,220 meters in the Andes in Bolivia, is known for the discovery of the pion in 1947 and for research conducted by Nobel Prize-winning scholars. Despite the glacier's disappearance in 2009 due to climate change, the site continues to be used for greenhouse gas monitoring.
Bolivia intends to nominate the Chacaltaya Cosmic Physics Laboratory as a UNESCO world heritage site. This was reported by the Efe agency, underlining that the structure, which belongs to the state university, is located at 5,220 meters above sea level in the Andes and is considered the highest in the world in its area.
The director of the Physical Research Institute, Martín Subieta, explained that the main reason for the request "is the history linked to great scientific goals that have been achieved on this mountain". Among these, the confirmation of the existence of the pion stands out, a subatomic particle detected in 1947. The research directly involved two Nobel Prize-winning scholars.
Despite the glacier's disappearance in 2009 due to climate change, the area continues to host greenhouse gas monitoring stations. In parallel, a short distance away, a new cosmic ray observatory is being built with the support of Japan.
