A team of scientists using the Stratospheric Observatory for Infrared Astronomy (SOFIA) has pinpointed the amount and location of water vapor around a newly forming star with groundbreaking precision.

Using data collected aboard SOFIA, the team determined that most of this young star's water vapor is located in material flowing away from the star, rather than within the disk of matter orbiting around it. This location is unexpected, indicating that if planets formed around this star, they might receive only a small fraction of the water in the system.

These observations were made possible by using SOFIA's airborne vantage point in the Stratosphere - at an altitude above 99% of Earth's water vapor, which prevents this type of measurement from the ground - as well as the precision and sensitivity of the EXES (Echelon-Cross-Echelle Spectrograph) instrument aboard SOFIA.

The instrument spreads infrared light into its component colors with very high detail, providing scientists with more information about this light than was previously possible.

"This detection of water vapor would have been impossible for any ground-based observatory, and there are currently no space-borne telescopes providing this capability," said SOFIA project scientist Pamela Marcum.

"These mid-infrared observations allow us to directly measure the amount of water vapor in this young star, expanding our understanding of the distribution of water in the universe and its eventual incorporation into planets. The water detected today could be the oceans of tomorrow in planets that form around these new stars."

These findings were published in Astrophysical Journal Letters in 2015. The team was led by scientists at the University of Michigan, Ann Arbor, Mich., and Johns Hopkins University, Baltimore Md, and the University of California at Davis.

SOFIA is a Boeing 747SP jetliner modified to carry a 100-inch diameter telescope. It is a joint project of NASA and the German Aerospace Center, DLR. NASA's Ames Research Center in California's Silicon Valley, manages the SOFIA program, science and mission operations in cooperation with the Universities Space Research Association headquartered in Columbia, Maryland, and the German SOFIA Institute (DSI) at the University of Stuttgart. The aircraft is based at NASA's Armstrong Flight Research Center's Hangar 703, in Palmdale, California.
