[00:00:00]Could a star's space weather decide whether its planets can support life?

[00:00:03]Scientists just found a surprising new way to answer that question. For years astronomers noticed strange repeated dips in starlight around young M [music] dwarf stars. Nobody could explain them until now. Those dips turned out to be enormous rings of cool plasma locked inside the star's magnetic field forming a natural torus structure rotating with every spin. Carnegie scientist Luke Booma calls them built-in space weather stations revealing how energetic particles and magnetic storms behave around these stars without placing a single instrument there. This matters enormously. Most rocky Earth-sized planets orbit M dwarf stars and space weather could be the deciding factor between a living world and a dead one.
