We identify a point-symmetrical morphology comprised of seven pairs of opposite bays in the core-collapse supernova (CCSN) remnant Crab Nebula, which is consistent with the jittering jets explosion mechanism (JJEM) of CCSNe. We use a recently published infrared image of the Crab Nebula and apply image analysis to fit seven pairs of bays in the Crab, each pair of two bays and a symmetry axis connecting them. The seven symmetry axes intersect close to the explosion site, forming a point-symmetrical structure. We explain the bays as clumps that move slower than the low-density ejecta that the pulsar accelerated. Jittering jets that exploded the Crab formed the clumps during the explosion process. This shows that jittering jets explode even very low-energy CCSNe, as the Crab is, adding to the solidification of the JJEM as the primary explosion mechanism of CCSNe.

  1. Long-lived intermittent accretion disks in the jittering jets explosion mechanism (JJEM) of core-collapse supernovae

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    Viscous angular-momentum transport and jet feedback can keep intermittent accretion disks around newborn neutron stars alive long enough to launch the energetic jet pairs seen in some supernova remnants.

  2. Identifying a circum-jet southern ring counterpart to the northern jet of the Crab Nebula

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    A southern circum-jet ring in the Crab Nebula is identified and attributed to a counterjet within the jittering-jets explosion mechanism framework.

  3. Natal kick by early-asymmetrical pairs of jets to the neutron star of supernova remnant S147

    astro-ph.HE 2025-06 conditional novelty 5.0 of 10

    Two close-in-time episodes of unequal, opposite jets, not a single jet pair, can explain the bipolar ears and the ~570 km/s kick of the neutron star in remnant S147.

  4. The two alternative explosion mechanisms of core-collapse supernovae: 2024 status report

    astro-ph.HE 2024-11 reject novelty 4.0 of 10

    A review paper argues that neutrinos alone cannot power most core-collapse supernova explosions and that jittering jets from the newborn neutron star are the primary explosion mechanism.
