The discovery and the sound of pulsars

04 May

Supernovae are massive explosions of stars that until 1932 did not have many explanations, although they are observed and studied by astronomers.
Walter Brade and Fritz Zwicky sought the explanation when the subatomic particle called neutron was discovered so they understood that the answer was this, a neutron star.
It is a dense nucleus, as if two suns compressed in a space of the region of the great Sao Paulo of Brazil, but the explanation does not end there.
In 1967, the doctoral student Jocelyn Bell, captured in a radio astronomy equipment a weak pulse coming from a part of the sky with extreme precision, the house 1.3 seconds it repeated, it seemed an intentional signal of somebody or of and some civilization thought his counselor, but it was the discovery of pulsars.
Two important consequences of observation: to the extent that this star collapses its rotation increases greatly, and the other, is that collapse carries along with it the magnetic field forming a dense nucleus that spurs an energy beam dense to the space as pulses.
Russian scientists, capturing the flow of 10 pulsars, have created a song that along with other sounds of the universe form a great symphony of the creation and expansion of the universe.
