A professor of Southwest China's Sichuan University with an online username Tianshu, is the creator of the picture. With over 20 years of experience in photography project the "roof of the world", he captured the mountains using four separate photos on November 7, 2018.

"As the plane was flying over the Nepal-China border, I took the photos from the window seat on the left side of the plane,"he said. "The pictures record a range of around 480 kilometers from Mountain Makalu to Mountain Annapurana."

Tianshu emphasized the importance of weather to his shooting. "I was very lucky to encounter such clear weather; it is extremely rare to see so little clouds at such high altitude."

Tianshu and his friend James Xia, also known as Lao J Bu Lao on Sina Weibo, spent dozens of hours marking the names and heights of the 840 peaks. They referenced numerous photo albums, and made image comparisons using a variety of services, including Google Earth. Tianshu said the labeling work is still under way, and the number of markings may exceed 1,000 when completed.

Many mountaineers and experts said they have never seen a panorama of the Himalayas with such range and detail. It may be the clearest, widest and most specific photograph of the snowy Himalaya Mountains that currently exists.
