Hypernova

En Hypernova kan udsende en gammastr�le-burst med en ca. 100 gange s� h�j effekt som en supernova i forbindelse med eksplosionen. Hypernova-eksplosionen, der n�ede os den 29. marts 2003, udsendte en effekt p� 1 million gange effektenen fra vores galakses samlede stjerner.

Universet udg�res af elementarpartikler og vakuum. Partiklerne er fordelt uj�vnt og partiklerne og partikelklynger ben�vnes forskelligt afh�ngig af t�thed og m�ngde; klyngerne sp�nder lige fra subatomare partikler til sorte huller.

En m�ngde af partikelklynger i vakuum er:

Gas | Atmosf�re | Solvind | Kosmisk str�ling | Asteroideb�lte | Stjernehob, Stjernet�ge | Solsystem | Galaksehob

However, the likely damage is not to humans directly, but to satellites and the upper atmosphere..."
