sorry that i put good old astronomers i ment conspiracists. Anyway Thanks for the input. I dont know what these different orbits you were talking about are? Still I am keen to learn. Is it true what he says in the article though? That apparently stars like ours occasionally flare up like mad with explosions that would make the biggest of coronary mass ejections look tiny. Not that i suppose i can worry cos theres not much we can do about that. Still I wouldnt of thought we could detect that just yet on other stars.
