Pulsating Stars (04:25)
In 1967, scientists discover signals coming from outer space, signals that some people think are coming from aliens. They are pulsating stars sending out beams of magnetic energy from their magnetic fields.
Pulsar: Unique Spin (05:47)
The spinning neutron star is a massive, natural electric generator. Its spin creates a powerful magnetic field. Every pulsar has a unique spin that identifies it and can be used as space locators similar to a GPS system on Earth.
Supernovas/Neutron Stars (05:16)
All planetary masses are annihilated by supernova blasts. Gigantic clouds of stellar debris contain pulsars or neutron stars. When they pulse, they create a pulsar wind nebula.
Millisecond Pulsars and Magnetars (02:48)
About 10% of pulsars are speeding up. Millisecond pulsars gain speed up to 1000 rotations per second from a binary companion star. Magnetars have magnetic power 1000 million million times stronger than Earth's magnetic field.
Pulsars: Electromagnetic and Sonic Waves (05:26)
Former Grateful Dead drummer Mickey Hart transfers electromagnetic waves to sonic waves. Pulsars produce radio waves that travel hundreds of light years to reach Earth.
Cosmic Symphony (03:41)
In a distant star cluster, 47 Tucanae, 22 millisecond pulsars each generate a distinct musical note. The music generated by these pulsars is a strangely haunting song from space. Some pulsars have their own planets.
Quasars outshine everything else in the cosmos. Quasars are huge black holes eating the material around them and irradiating light that can be seen almost all the way across the observable universe. Quasars do not exist in all galaxies.
Quasar Jets (07:48)
The energy emitted from the quasar's high-speed jet probably comes from gas and material that fall toward the black hole but is redirected by strong electromagnetic fields into the jet. A jet streaming out into space is called a DRAGN.
