Description: |
The Dark Side of The Sun Astronomy Lecture By Stony Brook University Astrophysicist at Southampton Cultural Center in Southampton, Suffolk County, Long Island, New York.
Stony Brook University astrophysicist, Frederick M. Walter, will discuss the Sun and how solar phenomena can have potentially catastrophic consequences, like bringing down the North American power grid.
The Sun, a perfectly ordinary middle-aged intermediate mass star, is absolutely critical for life as we know it on Earth. Essentially all the energy we, and all life, has to work with comes from the Sun. Nothing the Sun has done in the past 4 billion years has wiped out life on Earth. But today human beings are advancing in new ways that bring us into direct conflict with less-appreciated aspects of Solar behavior.
Solar magnetic activity causes sunspots and heats the chromosphere and corona. Recombining magnetic fields cause solar flares, solar proton events and coronal mass ejections (CMEs). These reach the Earth, causing the spectacle of the aurorae (the Northern and Southern Lights). More recently, these phenomena have endangered astronauts and destroyed satellites. CMEs play havoc with the power grid, and there is an uncomfortably-high probability that in the near future a large CME will bring down the North American power grid, with catastrophic consequences.
Prof. Walter will review the spectacle of Solar magnetic activity, and lay out the case that modern civilization is inadequately prepared for these new threats, and discuss what we can do about it.
Frederick M. Walter has been a Professor of Astronomy at Stony Brook University since 1989. His fields of research include star birth, stellar weather, and star death using the Chandra and XMM-Newton X-ray Observatories, the Hubble Space Telescope, and telescopes in Arizona, Hawaii and Chile.
The lecture will be followed by guided tours of the night sky through a telescope, weather permitting. This event is free but donations to help support our educational programs are appreciated.
Montauk Observatory
The Montauk Observatory Inc. is a not-for-profit organization, designated as a 501(c)3, with a Mission to provide free year round educational programs, including astronomy lectures and professional planetarium shows. The goal is to build a wonderful observatory building on the East End of Long Island for its state-of-the-art professional grade telescope and to provide discovery programs accessible via the internet.
The leadership of the Montauk Observatory believes that astronomy is a pathway into the study of science which is so often not available to young people and the public today. Our futures are linked to the re-emergence of the love of science and the discoveries that will bring. |
