2011年2月7日 · They mapped water vapor along a ridge of warm material in the Orion nebula nearly 18 light-years in length. The Orion ridge is associated with the closest region of massive star formation to the Earth, a complex that has long been a key site for astronomers investigating how stars form, which physical processes are at work, and what chemistry ...

1998年4月17日 · But when, like an orbiting dowser, instruments aboard the Infrared Space Observatory (ISO) picked up an intense glow from a cloud near the Orion Nebula, astronomers knew they had found a concentration of water that makes the Pacific Ocean look like a …

2024年10月15日 · Astronomers have identified the largest and most distant water reservoir ever detected in the universe. This immense collection of water, equivalent to 140 trillion times the water in Earth's oceans, surrounds a quasar over 12 billion light-years away.

2024年2月23日 · An international team, including Western astrophysicists Els Peeters and Jan Cami, has found the destruction and re-formation of a large quantity of water in a planet-forming disk located at the...

2024年2月25日 · Researchers Find Destruction of Oceans’ Worth of Water per Month in Orion Nebula OH as a Probe of Warm-water Cycle in Planet-forming Disks (journal link)

2023年12月5日 · In a first-of-its-kind discovery, the James Webb Space Telescope has detected water in the inner region of a disk of planet-forming gas and dust surrounding an infant star.

2024年2月26日 · An international team, which included Western astrophysicists Els Peeters and Jan Cami, discovered the destruction and re-formation of large amounts of water in a planet-forming disk located in the heart of the Orion Nebula. This discovery was made possible thanks to an original multidisciplinary approach combining observations from the James ...

2014年6月17日 · Using ESA's Herschel space observatory, astronomers have discovered that a molecule vital for creating water exists in the burning embers of dying Sun-like stars. Water-building molecule in Helix Nebula. When low- to middleweight stars like our Sun approach the end of their lives, they eventually become dense, white dwarf stars.

2014年8月1日 · We will show that the available amount of this water depends on the conditions in the parental cloud the planetary system has formed from. These clouds can be giant gas clusters with a complex structure associated with bright nebulae or smaller gas aggregations appearing as quiescent dark regions.

Despite the long-standing debate on which mechanisms contributed to the water content on rocky planets in our solar system (exogenous versus endogenous), our work shows that water gas-solid interaction can lead to hydration of the pristine forsterite surface …
