Lucie
Green takes us on a journey from the centre of the sun to planet earth
in a run-down of the latest solar physics research.

110
times wider than Earth; 15 million degrees at its core; an atmosphere
so huge that Earth is actually within it: come and meet the star of our
solar system.
Light takes eight minutes to reach Earth from the
surface of the Sun. But its journey within the Sun takes hundreds of
thousands of years. What is going on in there? What are light and heat?
How does the Sun produce them and how on earth did scientists discover
this? Since the Royal Institution was founded in 1799 our knowledge of
the Sun has changed dramatically and much of the work was carried out at
the Ri.
Join Lucie Green for an enlightening talk, taking you
from inside the Sun to its surface and to Earth, to discover how the Sun
works, how a solar storm can threaten the modern technology that
society relies on and more of the latest research in solar physics.
Lucie
Green is a Professor of Physics based at the Mullard Space Science
Laboratory, UCL’s Department of Space and Climate Physics. She studies
activity in the atmosphere of our nearest star, the Sun. In particular,
she looks at immense magnetic fields in the Sun’s atmosphere which
sporadically erupt into the Solar System.
Lucie is very active in
public engagement with science, regularly giving public talks and
appearing on TV shows like Sky at Night.
