EARTH'S MAGNETIC FIELD IS CHANGING:
Earth's magnetic field protects us from stormy space weather and cosmic
rays. New data from Europe's SWARM spacecraft show that our planet's
magnetic field is changing. For instance, in recent years magnetism
over North America has weakened by 3.5%, while Asia has seen an
increase of 2%. Other parts of the world are unsettled as well. Visit Spaceweather.com for the full story.
Soon, the season for noctilucent clouds over the northern hemisphere
will begin. A sky watcher in Scotland might have spotted the first
apparition on May 10th. Electric-blue clouds are highlighted on
today's edition of Spaceweather.com.
