Gaia is an innovative spacecraft designed and launched by ESA in 2013 with the goal of creating the most detailed view of stars in the Milky Way! This pattern is for a cute and cuddly version of Gaia that you can hold in your hand or hang up as decor!

The universe can be three possible shapes: spherical, flat, and hyperbolic. This pattern includes instructions for all three shapes with two variations for the flat universe and many more for the hyperbolic one.

Black holes are the final stage of large stars in the current universe. These large stars stop being able to fuel themselves with nuclear fusion, and their gravity causes them to collapse to the point where not even electrons and neutrons can hold up the star. This is why stellar sized black holes are sometimes called collapsars.

Accretion disks are disks of high energy gas orbiting a massive star or a black hole. The material in the disk moves at extremely fast speeds, so friction between the gas particles causes them to heat up and emit radiation, giving them their orange glow.
