Stars Incubator
Star Incubator - Creating Stars in Minecraft
The process of star creation requires special care and sequential actions. First, you'll need a special base for the future star.

After that, you need to compress the structure with obsidian to form a star core.

The next stage is adding glowstone and Ender pearls to create an unstable star.

Be extremely careful as this form is highly unstable and requires gentle handling!
To stabilize it, place the object in a furnace where it will transform into a full-fledged star.

Final step: go to the Nether and activate the star (right-click). With a successful outcome, you'll get a Nether Star, but be prepared - failure will cause the object to break into pieces.
