Underneath the crust of spinning neutron stars, there’s a material that is not only strong, but looks like pasta? Nuclear pasta to be exact. Here’s what else scientists know.

The Elasticity of Nuclear Pasta
“The breaking strain of materials in neutron star (NS) crusts are relevant for a variety of electromagnetic and gravitational wave phenomena. Crust breaking may occur in magnetar outbursts, resonant crust shattering in NS mergers, and in the starquake model for pulsar glitches. Likewise, the shear modulus of crust matter may affect the oscillation frequency of magnetar flares, the damping of r-modes, and determine the height and lifetime of mountains on a NS.”

Nuclear Pasta In Neutron Stars May Be The Strongest Material In The Universe
“About a kilometer below the surface of a neutron star, atomic nuclei are squeezed together so close that they merge into clumps of nuclear matter, a dense mixture of neutrons and protons. These as-yet theoretical clumps are thought to be shaped like blobs, tubes or sheets, and are named after their noodle look-alikes, including gnocchi, spaghetti and lasagna.”

LIGO: Sources and Types of Gravitational Waves
“Continuous gravitational waves are produced by a single spinning massive object, like an extremely dense star called a neutron star. Any bumps or imperfections in the spherical shape of this star will generate gravitational waves as the star spins.”
