Astronomy Now’s Greg Smye-Rumsby offers tips on how to safely view the partial solar eclipse of 20 March 2015.
Although thick cloud in parts of Indonesia spoiled the view for some along the path of totality, tens of millions more were greeted to spectacular views of the 9 March total solar eclipse. NASA, in partnership with the Exploratorium Science Center, hosted live coverage of the event from the coral island of Woleai in the Pacific Ocean.
A team of scientists has documented atmospheric changes on Io, Jupiter’s volcanically active satellite, as the giant planet casts its shadow over the moon during daily eclipses. Io’s thin atmosphere collapses as the sulfur dioxide gas emitted from volcanoes freezes when shaded by Jupiter. The atmosphere reforms when Io moves out of eclipse and the ice sublimates.
