The Crab Nebula. An oval nebula with complex structure against a black background. On the nebula’s exterior, particularly at the top left and bottom left, lie curtains of glowing red and orange fluffy material. Its interior shell shows large-scale loops of mottled filaments of yellow-white and green, studded with clumps and knots.
