Description:
Explosion of Eta Carinae shown by HST. The first explosion in about 1840 produced twin lobes which show no filament-structure due to their electrically non-charged matter. The later explosion shows weak filaments which appeared in about 1890, only around the centre. A model can be given why was this second explosion electrically charged. 3 D picture: by Jon Morse Uni. of Colorado.
