Description |
Pulsars are the collapsed cores of once-massive stars. They are giant flywheels in the Universe and the fastest one can spin up to an incredible 700 times per second. At the same time they have extremely strong magnetic field up to multiple quadrillions of times larger than that of the Earth. The Parkes telescope has discovered more pulsars than all the rest of the telescopes put together. Once discovered and followed-up, these pulsars allow scientists to test theories of gravity, search for the signatures of massive black holes spiralling together and help determine how nuclear matter is bounded together. We hope to understand these exotic stars and to use them as a probe to study the fundamental physics that governs the Universe.
