View Of Comet Helps Solve Mystery Of Earth's Abundant Water

Handout - This artist’s concept of Comet 238P/Read shows the main belt comet sublimating—its water ice vaporising as its orbit approaches the Sun. This is significant, as the sublimation is what distinguishes comets from asteroids, creating their distinctive tail and hazy halo, or coma. The James Webb Space Telescope’s detection of water vapor at Comet Read is a major benchmark in the study of main belt comets, and in the broader investigation of the origin of Earth’s abundant water. NASA's James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for solar system scientists studying the origins of Earth's abundant water. Using Webb's NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapor – around a comet in the main asteroid belt for the first time, indicating that water ice from the primordial solar system can be preserved in that region. Comet Read is a main belt comet – an object that resides in the main asteroid belt

Handout - This image of Comet 238P/Read was captured by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope on September 8, 2022. It displays the hazy halo, called the coma, and tail that are characteristic of comets, as opposed to asteroids. The dusty coma and tail result from the vaporization of ices as the Sun warms the main body of the comet. NASA's James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for solar system scientists studying the origins of Earth's abundant water.

Comet Read is a main belt comet – an object that resides in the main asteroid belt but which periodically displays a halo, or coma, and tail like a comet. Main belt comets themselves are a fair

Chinese expedition on Mt. Qomolangma explores effects of ultra-high altitude on humans

STORY: Chinese expedition on Mt. Qomolangma explores effects of ultra-high altitude on humans DATELINE: May 2, 2022 LENGTH: 0:01:12 LOCATION: SHIGATSE, China CATEGORY: SCIENCE/ENVIRONMENT SHOTLIST: 1. various of the expedition 2. SOUNDBITE (Chinese): ZHU TONG, Academician with Chinese Academy of Sciences STORYLINE: As a testing object himself, Zhu Tong, an academician with the Chinese Academy of Sciences, led his team on Sunday to explore the effects of ultra-high altitude environments on human health at the Mount Qomolangma base camp for mountaineering at an altitude of 5,200 meters. The research is an important project of the comprehensive scientific expedition on Mount Qomolangma, part of China's second scientific research survey on the Qinghai-Tibet Plateau. 　　 SOUNDBITE (Chinese): ZHU TONG, Academician with Chinese Academy of Sciences "In many tough places that are rarely traveled by people, unknown scientific problems are waiting for us to observe, explore, and solve. Therefore, in addition to the b
