COSMIC MUSINGS - "Another Day of Sun"

COSMIC MUSINGS series presented by United Airlines. 



We take the Sun for granted. Even when it rains, the Sun always shines above the clouds. It rises and sets at predictable times and we go about our daily business. In SoCal, it’s just another day of Sun.


But do we really know our stellar companion? What does it mean, to live in the neighbourhood of a star like the Sun? Let us see the Sun in all its true colors (from radio waves to X-rays), learn about its temper tantrums (solar storms), and feel the magnetic bond between the Sun and Earth. Let us witness the Sun orchestrate the symphony of space weather, and show us the plasma-filled cosmos where electrons and protons run wild. Let our newfound wisdom guide us to habitable planets around other stars. Let us learn to live with the Sun.


Register today to join Friends Of The Observatory to learn about streams of plasma and electric currents churning inside the Sun to create magnetic fields, the role of magnetic fields in heating the solar corona to millions of degrees, which emit UV and X-ray radiation, and drives a magnetized wind pervading interplanetary space. Together with solar flares and coronal mass ejections, the Sun's radiation and wind create space weather on Earth and other planets. Learn about how new discoveries from space missions, ground-based telescopes, and massively parallel computer simulations teach us about about the Sun, and how these lessons are used to understand other stars.

Dr. Miho Janvier
Astrophysicist, Institute for Space Astrophysics

Dr. Miho Janvier is an astrophysicist at the Institute for Space Astrophysics (IAS) in Orsay. While she may have stepped foot at a young age into the field of astronomy in the hope of finding aliens (!), she now focuses as a professional astronomer on the special relationship between the Sun and the planets of the solar system. She is a WIRED Innovation Fellow and a TED Fellow, and has done a lot of outreach activities. She has also developed educational contents using new technologies like virtual and augmented reality ( Miho is also involved in the future European Space Agency mission to the Sun (Solar Orbiter, to be launched in 2020) as a deputy project scientist on the SPICE instrument and scientific co-investigator on the EUI instrument aboard the spacecraft.

Dr. Mark Cheung
Staff Physicist, Lockheed Martin Solar & Astrophysics Lab

Dr. Mark Cheung is a Staff Physicist at Lockheed Martin Solar & Astrophysics Lab in Palo Alto, CA and a Visiting Scholar at Stanford University. Mark is the Principal Investigator for the Atmospheric Imaging Assembly ( on NASA’s Solar Dynamics Observatory (, which has been monitoring the Sun since 2010. Mark is an advisor for NASA’s Frontier Development Lab (hosted at NASA Ames and the SETI Institute), where they apply machine learning and artificial intelligence techniques to accelerate space science discovery and exploration. Originally from Hong Kong, Mark grew up in Australia and did graduate research at the University of Göttingen, Germany and the Max Planck Institute for Solar System Research. He has witnessed four spectacular total solar eclipses, three of them at the beach and most recently at a vineyard in Oregon.


Check-in and the Café at the End of the Universe open at 6:00 p.m. The Observatory will be closed to the general public, and the only area/exhibits inside the building open to ticketed guests is in the immediate vicinity of the Leonard Nimoy Event Horizon theater. The presentation begins at 7:30 p.m. in the Leonard Nimoy Event Horizon theater.



Reservations are required to access event parking and enter Griffith Observatory. In the case of sold-out shows, ticket sales will close. Non-wait list tickets not picked up by 7:40 p.m. will be made available to wait-listed guests. The event wait list may be joined by emailing, including the number of seats requested and a full name for the reservation. Wait list tickets are sold at the door, cash (exact change) only. No refunds are available. All registration closes July 23, 4:00 p.m.
