A team of scientists from Auckland and Tasmania has finally seen what is known as a stellar glitch after monitoring the Vela Pulsar neutron star for some four years.
The glitch occurs every three to four years when the core of the star, which has been spinning separately from the crust, grabs that crust and causes it to speed up.
It's a big deal and the scientists were able to capture the moment and Dr Willem van Straten from AUT's Institute for Radio Astronomy and Space Research discusses its significance.
