Supernova

Bright flash of light in the sky that the Danish astronomer surprising, Tycho Brahe, over 400 years ago is not something strange. At least after a team of scientists discover the secret behind the events that are rarely seen naked eye.

Until now, scientists believe that the bright light coming from exploding stars or supernovas. But what kind of supernova that caused is still an enigma of nature until now.


Recent research published in the journal Nature found that bright light came from the explosion of a white dwarf binary type (white dwarf). The conclusion was obtained after combined scientists from Germany, Japan and the Netherlands, who observed reflections produced after many years.

The story of an event known as Tycho's supernova began to spread on November 11, 1572. As Brahe was surprised to see a bright light in the sky that claimed a very bright star in the constellation Cassiopeia new surroundings. However, a light as bright as the planet Venus was only last two weeks and disappear completely after 16 months.

Since that time no telescope, Brahe recorded in detail. Unlike the moon or the planets, the position of not shake the shiny object in relation to other stars. This shows that the light was far behind.
Shortly events are the panoramic views of being in the same place. Since then, the commitment of Brahe more intensive study of star and start a tradition of modern astronomy.

The resulting light of exploding stars were already far beyond the Earth hundreds of years ago. However, the resultant powder, and still dispersed in the gas space, so that the event can still be followed. Recent research is also performed based on analysis of wave reflection may also be recorded at this time.
