Sky & Telescope February 2011 Print Issue
In 1859 a powerful solar storm disrupted telegraph networks worldwide and produced auroras nearly to the equator. Two leading scientists explain what will happen to our modern technological society if the Sun unleashes another storm of similar magnitude. Other articles in this special thematic issue about the Sun discuss recent results and images from NASA's Solar Dynamics Observatory, amateur solar radio astronomy, and how to take great pictures of our nearest star.
