Victoria Kaspi is an astrophysicist whose research focuses on neutron stars: massive, dense celestial objects that emit bursts of radiation as they rotate, and that are formed when a massive star explodes.

Kaspi studies heavy-duty physics – a neutron star is so dense that one teaspoon would weigh 100 million metric tonnes. She uses the largest and most powerful radio and X-ray telescopes in the world to study their physical behaviour. Since neutron stars are the remnants of exploded stars, understanding how they behave reveals how massive stars collapse and what happens during this process. Kaspi’s work sheds light on the nature of matter under extraordinary circumstances, as well as in less extreme settings here on Earth.
