Abstract

We present a new, very large, highly-elongated, undulating, gaseous

structure lying just beyond the current orbit of the Sun in the Milky

Way. The structure was discovered using 3D-dust mapping techniques, and

it encompasses several star-forming regions formerly associated with

"Gould's Belt" and the "Local Arm" of the Galaxy. Gaia data, along with

several other large surveys, were critical to this discovery. We will

present several three-dimensional views for this new object, and

speculate on its origins.
