A colorful, roughly circular supernova remnant, named Cassiopeia A. The center of this remnant contains a white dot, which is a neutron star. The neutron star is surrounded by smoke-like filaments of different colors and densities that extend outward toward the edges of the image. The star is surrounded by thinner, blue, and orange filaments. These filaments also weave throughout the remnant in different concentrations with more of the blue filaments wrapping around the edges of the supernova remnant, and orange filaments shooting out of the remnant toward the top left. In the bottom left, there is a dense field of purple gas. Between the star and edges of the remnant are a dense mix of orange, green, and purple filaments that create a clumpy ring-like shape.
