The Crab Nebula. An oval with complex structure extends from lower left to upper right against a black background. On the oval’s exterior lie curtains of glowing yellow and green fluffy material. Its interior shell shows large-scale loops of mottled filaments of yellow-white and green, studded with clumps and knots. Translucent thin ribbons of smoky blue lie within the remnant’s interior, brightest toward its center. The blue material follows different directions throughout, including sometimes sharply curving away from certain regions within the remnant. A faint, wispy ring of blue material encircles the very center of the nebula. Around and within the supernova remnant are many points of blue, green, purple, and white light.

Summary

New data revises our view of this unusual supernova explosion.

The Crab Nebula is a nearby example of the debris left behind when a star undergoes a violent death in a supernova explosion. However, despite decades of study, this supernova remnant continues to maintain a degree of mystery: What type of star was responsible for the creation of the Crab Nebula, and what was the nature of the explosion?

NASA’s James Webb Space Telescope has provided a new view of the Crab, including the highest-quality infrared data yet available to aid scientists as they explore the detailed structure and chemical composition of the remnant. These clues are helping to unravel the unusual way that the star exploded about 1,000 years ago.
