The odd behavior known as a “glitch,” is best observed in the Vela Pulsar, a neutron star located 1,000 light years away.
A group of scientists - led by a team from the Australian University of Monash - pored over data taken from a glitch event in 2016 using data from the Mount Pleasant Radio Observatory in Tasmania.
"Immediately before the glitch, we noticed that the star seems to slow down its rotation rate before spinning back up.
The glitch can be explained by visualizing a neutron star as three separate parts.
Glitches are thought to be caused when excess angular momentum from neutrons in the inner crust is transferred to the particles in the outer crust.

After the glitch, the star’s rotational frequency tapers off, Paul Lasky, an astrophysics lecturer at Monash University, explained.
