SUMMARY: The Canadian-built MOST space telescope has shed new light on how stars like our own Sun can actually be quite turbulent, vibrating and flaring up unexpectedly. MOST tracked a star called eta Bootis for 28 straight days without interruption, and measured its brightness more than 250,000 times - 10 times more accurately than any previous instrument could reach. MOST should also assist planet hunters by watching how a star brightens and dims as planets pass in front of it, similar to Venus' recent transit across the face of the Sun.
