Astronomers analyzing 3D maps of the shapes and sizes of nearby molecular clouds have discovered a gigantic cavity in space.
 

The sphere-shaped void, described today in the Astrophysical Journal Letters, spans about 150 parsecs—nearly 500 light years—and is located on the sky among the constellations Perseus and Taurus. The research team, which is based at the Center for Astrophysics | Harvard & Smithsonian, believes the cavity was formed by ancient supernovae that went off some 10 million years ago.

There's a Sky & Telescope article on the Perseus-Taurus Supershell, complete with a video, at https://skyandtelesc...star-factories/

I was going to start a new thread on this but found this thread with more information and links!  Here's another article with some links to your primary sources. This topic adds some ideas about star forming by using 3D maps. You can't tell which object is where with 2D images and this you tube video shows the misinterpretation that can result.

 

We need 3D ZWO cameras and projectors! Imagine having M31 projected in 3D above your table top, then rotate it to view at different angles!
