Xie's team reports that the disk reflectance spectrum of HD 181327 at 90–105 AU from it has a broad bowl-shaped dip between 2.7 and 3.4 µm. This is consistent with the 3 µm feature of water ice.

An artist's impression of the water-ice–bearing debris disk around HD 181327. NASA, ESA, CSA, STScI, Ralf Crawford STScI Astronomers have been waiting for such a definitive detection of water ...

HD 181327’s Dynamic Debris Disk Is A Scene Of Constant Collision The star HD 181327 is estimated to be around 23 million years old, considerably younger than our 4.6-billion-year-old Sun.

NIRSpec detected the signature water in HD 181327's spectrum, principally at a wavelength of 3 microns (millionths of a meter), with a peak coming at 3.1 microns.

The researchers observed HD 181327 using JWST's near-infrared spectrograph (NIRSpec), which revealed the telltale chemical traces of water in the outer reaches of the system's debris disk.

Caption The marked asymmetry of the debris disk around the star HD 181327 (shown here in a Hubble image) suggests it may have formed as a result of the collision of two small bodies. Disk ...

NASA's James Webb Space Telescope detected water ice in the debris disk of HD 181327. The star HD 181327, located 155 light-years away, is only 23 million years old. Water ice makes up over 20% of ...

ALMA image of the ring of comets around HD 181327 (colours have been changed). The white contours represent the size of the Kuiper Belt in the Solar System.

In a historic finding, NASA's James Webb Space Telescope has confirmed that crystalline water ice exists in the debris disk surrounding HD 181327, a young star that resembles the sun. The ice that ...

Irregularities observed in one ring-like system in particular, around a star called HD 181327, resemble a huge spray of debris possibly caused by the recent collision of two bodies into the outer ...

NIRSpec detected the signature water in HD 181327's spectrum, principally at a wavelength of 3 microns (millionths of a meter), with a peak coming at 3.1 microns.
