BayAstro – Events of Week of 11/30/2020 and Beyond

The BayAstro group publishes announcements of interesting events related to astronomy and aerospace in the San Francisco Bay Area. This can include events such as astronomy and interesting physical science lectures, club meetings, star parties, air shows and other events of interest mostly to amateur astronomers and science enthusiasts.

Histories of Communicating Science Beyond the Recent West – Livestream

We are often told science communication originated alongside professionalised science in Western Europe a few hundred years ago. Yet cultures all over the world and throughout time developed unique conventions for communicating their knowledge within their own societies and with others.
This webinar will discuss how we might rethink science communication histories to be more cross-culturally diverse and inclusive, without losing sight of cultures’ unique approaches to knowledge communication.
Our four exceptional speakers will draw on examples from across the world, including pūrākau that communicate mātauranga Māori, medieval European and Arabic pharmaceutical works, ancient Persian water science, and astronomical knowledge in the cuneiform world of Babylonia and Assyria.

Ngā rāwekeweke o Ngātoroirangi – The exploits of Ngātoroirangi: Multiple ways of Knowing
Speaker: Daniel Hikuroa
Arabic Pseudonyms and the “Princes of Medicine:” Conventions of Authorship in Pharmaceutical Texts of Medieval and Early Modern Europe
Speaker: Paula De Vos, San Diego State University
Communicating by doing: Communicating sustainability in Persia
Speaker: Ehasn Nabavi, Australian National University
Not a Less Perfect Version: Astronomical Knowledge in Cuneiform Antiquity
Speaker: Francesca Rochberg, UC Berkeley

Moderator: Lindy Orthia, Australian National University

Astronomy on Tap Santa Cruz: – Livestream

We can’t typically see black holes, but this month we will be discussing the exciting events that light them up.

At the center of most galaxies lies a supermassive black hole (SMBH), larger than our entire solar system and millions of times more massive than our Sun. Despite the considerable influence they have on their host galaxies, most SMBHs are very difficult to detect because they are hidden inside dense, bright clusters of stars. Occasionally, gas or even stars are pulled in by the black hole’s gravity, fueling the black hole’s growth. These ‘accretion’ events also produce bright flares of light that illuminate the black hole. Brenna Mockler (UCSC) and Sierra Dodd (UCSC) will discuss two of the most exciting types of accretion events: tidal disruption events and changing-look quasars.

After Dark Online: Celestial – Rising Tides – Livestream

In December and January, San Francisco Bay will see king tides, extreme tides caused by three colliding factors: the sun and moon aligning – a full moon – while both are at their closest points to Earth. However, the sea level in the Bay is constantly rising, and today’s king tides could be tomorrow’s regular high tides. Learn more about king tides and how sea level rise will impact the Bay Area, as well as how local groups are planning for shifting shorelines and envisioning a more resilient future.

The movements and mechanics of the planets, moons, and stars create awesome effects for us observers on earth. Predictable yet coincidental, these cycles among the stars lead to gravitational bulges, lunar alignments, and a turnaround of apparent motion. Join us this month as we explore these effects as opportunities for wonder and harbingers of future change.

Ages 18+

Asteroseismology & Exoplanets with the NASA TESS Mission & Sky in December – Livestream

The NASA transiting Exoplanet Survey Satellite (TESS) was launched in 2018. It is providing exquisite photometry to enable searches for new exoplanets and studies of stars and other objects. In this talk I will discuss how we are using these data to conduct asteroseismic studies of stars, by detecting intrinsic stellar pulsations, and providing detailed characterisations of host stars and hence their newly discovered planets.

Mapping the Heavens: Celestial Cartography from Ancient to Modern Times

In this online talk, Nick Kanas will explore the evolution of celestial cartography. People have observed the night sky since antiquity in an effort to predict celestial events and understand their place in the universe. Many cultures organized the stars into heavenly patterns that reflected issues important to them. In ancient Greece, the stars were placed in constellations that were viewed as allegorical representations of classical Greek heroes, heroines, and monsters. These images formed the backbone of the cosmological and constellation maps that appeared in stunningly beautiful star atlases of the 17th and 18th Centuries. But telescopic and scientific needs called for more accuracy in star placement, and gradually the heavenly bodies were positioned in increasingly accurate coordinate systems superimposed on the sky. Constellation images became redundant, and they have largely disappeared in today’s modern star atlases.

Nick Kanas, M.D., is a Professor Emeritus (Psychiatry) at the University of California, San Francisco, and a Fellow of the Royal Astronomical Society. He has conducted NASA-funded research, has been an amateur astronomer for over 60 years, and has collected antiquarian celestial maps, books, and prints for nearly 40 years. He has given a number of talks on celestial cartography to amateur and professional groups, and he has written two books on the subject: Star Maps: History, Artistry, and Cartography, now in its 3rd edition, and Solar System Maps: From Antiquity to the Space Age.

After Dark Online: Celestial – Solar Eclipse – Livestream

On December 14, the shadow of the moon will cross Earth in a rare event called a total solar eclipse. For a small portion of Earthly observers – in this case, those in a narrow stripe across South America – the moon will be perfectly lined up between our planet and the sun, casting an eerie darkness and offering a magnificent view of the solar corona. Join us to learn more about this fascinating alignment and prime yourself for the upcoming eclipse.

Predictable yet coincidental, these cycles among the stars lead to gravitational bulges, lunar alignments, and a turnaround of apparent motion.
