Our Plasma Universe Crab Nebula (NASA) Scientists think the things they've discovered about our Sun are true of other stars as well. Other stars have "solar" winds, and dying stars leave marks of their magnetism. When a dying star explodes, the expanding plasma is shaped by magnetic and electric forces into beautiful structures like the Crab nebula. Not only stars and planets are magnetic. Entire galaxies, including our own Milky Way, have magnetic fields too. Our knowledge sends us out to the stars As we come to understand space weather – the importance of plasmas, space storms and magnetic fields – our understanding of the universe becomes clearer. This knowledge helps us protect our technology and our way of life. It also prepares us to set sail through gusts of solar wind and take our first steps onto other worlds. Bon Voyage!
