The star is shedding its outer layers at extreme speeds, creating collision fronts where older, slower material meets newer, faster outflows. These shocks heat the gas and ignite the nebula’s filamentary structure in glowing hydrogen and oxygen emissions. Inside the shell, turbulent instabilities carve the fine threads and arcs, re

Oksana Korda | Astro Art & Science on Instagram: "The Milky Way is a barred spiral galaxy around 13.6 billion years old with large pivoting arms stretching out across the cosmos. Our home galaxy’s disk is about 100,000 light-years in diameter and just 1000 light-years thick. Just as Earth orbits the Sun, the solar system orbits the center of the Milky Way. Despite hurtling through space at speeds of around 515,000mph (828,000kmph) our solar system takes approximately 250 million years to complet
