Close and bright though it is, the Sun still defies a thorough
understanding. One reason is that some of the features on its roiling
surface are too small and short-lived to be studied even by the world's
largest solar telescopes.

With more than twice the aperture of existing solar telescopes (see 'Eyes on the Sun'),
the 4-metre ATST will be large enough to tease out small structures on
the Sun, particularly magnetic flux tubes — the hitherto unseen
precursors to sunspots. Sunspots, in turn, give rise to giant coronal
loops and flares, which can unleash bursts of radiation and cause
magnetic disturbances that sometimes threaten spacecraft, communication
networks and power grids.More details Click here
