​NOX MINIMA is a free sky map to print and to build by yourself. It is an elegant tridimensional dome displaying the stars and constellations of your place.
Star data comes from Hipparcos catalogue. The dome is a miniature night sky. The zenith is just at the top of the dome, which is not the case with flat representations. It is simple to perform a panoramic exploration of the sky, making it easier to identify the relative position of stars, constellations, the celestial pole, the ecliptic, etc.
The NOX MINIMA dome is part of the project: "Tapirapé: paper 3D planetarium", host by the School of Science and Technology of Federal University of Rio Grande do Norte, Brazil.
Beautiful, durable and easy to assemble
Print the 3 pages of the PDF of your city's sky. For better results, use medium weight papers (180 gsm).
Use scissors to cut along the lines shown in the animated gif. Ask an adult to help you with scissors.
Glue the segments joining the lines. Always do it from the bottom up, one sector at a time, pressing the glued parts against a flat surface and reinforcing the outside of the dome.
Do the same with the other two pieces of sky. Then glue them together, closing the dome, always from the bottom up.
