This photo taken on May 22, 2023 shows the Ngari Observatory at sunset in Ngari Prefecture, southwest China's Tibet Autonomous Region.
You Xianlong, a 36-year-old resident engineer at the Ngari Observatory in Tibet Autonomous Region, is responsible for equipment observation and operation maintenance along with seven colleagues. He is also the longest-serving engineer at the observatory.
You's career began in 2006 when he met Yao Yongqiang, a scientist at the National Astronomical Observatories under the Chinese Academy of Sciences (CAS), who was looking for workers to conduct long-term measurements in challenging plateau environments. Since then, You has been working at the Ngari Observatory for 17 years.
Selecting an observatory site is a complex process that involves examining terrain, geology, and support conditions. It also requires years of measurement and evaluation of factors such as the number of clear nights, astronomical seeing conditions, precipitable water vapor (PWV), and aerosol optical depth (AOD). These factors are closely related to astronomical observations.
Tibet's Ngari region, with an average altitude of over 4,500 meters, has proven to be an ideal location for establishing an astronomical observation base with full bandwidth.
From 2006 to 2011, the observatory's site selection team decided to construct an observation platform on a ridge south of Shiquanhe Town. You Xianlong and his colleagues took turns to keep a watch on the construction site. A typical round of shift would last at least three months.
During that period, You Xianlong and his colleagues faced a lot of difficulties such as limited food choices and threaten from wild animals.
In 2011, the observational platform was completed, marking the inception of the Ngari Observatory.
After over ten years of construction, the Ngari Observatory has now become one of the best astronomical observatories in the Northern Hemisphere. Yao Yongqiang believes that the facility will promote China's exploration into terrestrial planets and extraterrestrial life.
In the future, the observatory plans to build telescopes with diameters greater than ten meters. This prospect excites You Xianlong.

After over ten years of construction, the Ngari Observatory has now become one of the best astronomical observatories in the Northern Hemisphere. Yao Yongqiang believes that the facility will promote China's exploration into terrestrial planets and extraterrestrial life.
In the future, the observatory plans to build telescopes with diameters greater than ten meters. This prospect excites You Xianlong.

You Xianlong walks out a telescope dome at the Ngari Observatory in Ngari Prefecture, southwest China's Tibet Autonomous Region, May 24, 2023.
You Xianlong, a 36-year-old resident engineer at the Ngari Observatory in Tibet Autonomous Region, is responsible for equipment observation and operation maintenance along with seven colleagues. He is also the longest-serving engineer at the observatory.
You's career began in 2006 when he met Yao Yongqiang, a scientist at the National Astronomical Observatories under the Chinese Academy of Sciences (CAS), who was looking for workers to conduct long-term measurements in challenging plateau environments. Since then, You has been working at the Ngari Observatory for 17 years.
Selecting an observatory site is a complex process that involves examining terrain, geology, and support conditions. It also requires years of measurement and evaluation of factors such as the number of clear nights, astronomical seeing conditions, precipitable water vapor (PWV), and aerosol optical depth (AOD). These factors are closely related to astronomical observations.
Tibet's Ngari region, with an average altitude of over 4,500 meters, has proven to be an ideal location for establishing an astronomical observation base with full bandwidth.
From 2006 to 2011, the observatory's site selection team decided to construct an observation platform on a ridge south of Shiquanhe Town. You Xianlong and his colleagues took turns to keep a watch on the construction site. A typical round of shift would last at least three months.
During that period, You Xianlong and his colleagues faced a lot of difficulties such as limited food choices and threaten from wild animals.
In 2011, the observational platform was completed, marking the inception of the Ngari Observatory.
