IHY
builds on the success of the International Geophysical
Year (IGY). We now extend our global studies out into
the heliosphere and incorporate the drivers of
geophysical change into the global system. As we
approach the "new frontier" of the heliopause and
interstellar space, our heritage clearly extends back to
previous International Years.
The aim
of International Geophysical Year (IGY) in 1957 was to
understand the Earth's atmosphere and oceans and it
required scientists from countries all over the world to
co-ordinate their efforts. It was a monumental year
which saw the launch of the first artificial satellite,
Sputnik 1, and observations that confirmed the theory of
plate tectonics. IHY expands the science of IGY out into
the Solar System. Our Sun is a magnetic star and creates
a gigantic magnetic bubble which surrounds all the
bodies in the Solar System. The magnetic bubble is
called the heliosphere and it gives its name to
International Heliophysical Year (IHY).
The Primary Objectives of IHY are:
Advancing our Understanding of the Heliophysical
Processes that Govern the Sun, Earth and Heliosphere.
Continuing
the tradition of international research and advancing
the legacy on the 50th anniversary
of the International Geophysical Year.
Demonstrating the Beauty, Relevance and
Significance of Space and Earth Science to the World.
