THOUGHT FOR THE DAY

Vision

"The only way to predict the future is to have the power to shape it."

- Eric Hofer

TOPIC OF THE DAY

What is a Pulsar?

A pulsar is a rapidly rotating neutron star which emits large amounts of electromagnetic radiation (light, x-rays, radio waves, etc.) and particle jets. A neutron star is what is left over when a star 4 - 8 times the mass of our sun burns up most of its fuel and explodes in a supernova. The outer layers of the star shoot outwards rapidly, while the stellar core collapses to a sphere approximately 20 km in diameter. Some neutron stars do not rotate very rapidly but those that do are known as pulsars.
