(wave-shaped string of molecular clouds)
The Radcliffe wave is a string of star-forming regions forming a wave-like
shape (like a wavy string), which at its closest point is about 400
ly from Earth, stretching about 9000 ly in length. It
stretches over some length of the Local Arm, its wave-like shape
roughly a full wavelength, reaching above and below the galactic plane.
It was discerned in 2019/2020, using 3D data gathered from Gaia
and other observations. A portion of it consists of most of
Gould's Belt, and given that it is based upon recent, more-reliable
3D data, appears to be an actual physical structure whereas what
is currently termed Gould's Belt includes less-related clouds.
