The puzzle is almost a shapemod of Michael Sun's Curvy Helimate (a hybrid puzzle combining face and edge turning dodecahedron) with one notable difference - the stored cuts along the icosahedral edges. Diogo Sousa found the angle at which these splits happen. It is 58.2825256 - exactly half the jumbling angle.
As the puzzle is similar to the Skewby Copter but the edges still work after a 36 degree corner turn. See image 5. Combining it with the new splits the puzzle has almost ghost like quality - solving it back to its natural shape is not a trivial job. This makes the puzzle somewhat similar to the Rhomdo Transformer.
Stickers were supplied by Jason Gavril.
The name is in honor of the historic first photo of a black hole made by EHT (Event Horizon Telescope) project.
