Long Now Foundation

The Passage of Time and the Meaning of Life – Livestream

“Life is a process, not a substance, and it is necessarily temporary. We are not the reason for the existence of the universe, but our ability for self-awareness and reflection makes us special within it.” ― Sean Carroll

Sean Carroll is a Research Professor of theoretical physics at the California Institute of Technology, and an External Professor at the Santa Fe Institute. His research has focused on fundamental physics and cosmology, especially issues of dark matter, dark energy, spacetime symmetries, and the origin of the universe.
Recently, Carroll has worked on the foundations of quantum mechanics, the emergence of spacetime, and the evolution of entropy and complexity. Carroll is the author of Something Deeply Hidden, The Big Picture, The Particle at the End of the Universe amongst other books and hosts the Mindscapes podcast.

SETI Institute

Frank Drake Award Gala

The Frank Drake Award of the non-profit SETI Institute celebrates outstanding contributions to the scientific study of the origin, nature, and prevalence of life in the universe, and for work on techniques for the discovery of the existence of such life. (Past winners have included Nobel Laureate Charles Townes, and Bill Borucki, who created the Kepler mission to search for exoplanets.)

This year’s winners are SETI pioneers Paul Horowitz of Harvard and Dan Werthimer of Berkeley. The ceremony, hosted by Adam Savage (of television’s Mythbusters), features discussions with the winners, with Frank Drake himself, and with Jill Tarter.

The virtual ceremony begins at 6 pm on Thursday evening, May 6th, and you are cordially invited.

The Effect of ‘Mascons’ Interior Mass Distribution onto the Dynamic Environment Around Asteroids – Livestream

A sphere cluster (SPH-Mas) based gravity model allows a semi-analytic expression of the linearised equations around irregular-shaped celestial bodies Equilibrium Points (EPs) and an easy method for searching families of periodic orbits around them. The SPH-Mas model can retrieve the same dynamical objects of the shape model when the spheres share a uniform density distribution. The dynamics are solved for a rotating asteroid-fixed frame of angular velocity equivalent to the asteroid spin axis. The SPH-Mas model has the advantage to define the same particles mesh distribution for both astrophysical and astrodynamics tools. To the core of this study, we aim to gain a general insight on the dynamics around Didymos and other minor celestial bodies in term of stable and unstable orbits for studying the dynamics of ejecta particles.

Slugs and Steins: A Century of Paradigm Shifts in our Understanding of the Universe – Livestream

The past century has witnessed the birth of our modern view of the large scale universe as well as an astonishing list of startling changes or paradigm shifts in our understanding. The rate of new discoveries seems to be accelerating with time. This talk will take us from the contributions of Einstein and Hubble to the most recent discoveries about the early history of the universe. We will even discuss the discoveries expected from the next generation of scientific instruments as well as the likelihood of the unexpected discovery.

From Atomic Scales to Asteroid Surfaces: Understanding Space Weathering of Airless Bodies through Coordinated Analyses – Livestream

Soil grains on the surfaces of airless planetary bodies such as the Moon and asteroids are continuously being modified by their exposure to interplanetary space. These surface materials experience micrometeorite bombardment and irradiation by energetic particles from the solar wind, a phenomenon collectively known as space weathering. Such interactions change the chemical and microstructural characteristics of soil grains and, as a result, their optical properties which we can measure with remote sensing spacecraft. In order to understand the nature of space weathering processes on airless planetary surfaces, I combine nanoscale analyses of returned samples with experimental simulations of space weathering in the laboratory. I will present my work using various techniques to simulate micrometeorite impacts and solar wind irradiation of both returned samples and analog materials. I will present results from a novel technique to simulate micrometeoroid impacts using in situ heating inside the transmission electron microscope (TEM). I will also describe the results of new laser and ion irradiation experiments of carbonaceous meteorites which simulate space weathering on the surfaces of organic-rich asteroids. I will explore the microstructural and chemical signatures of space weathering in these samples and their relationship to changes in optical properties of the material. Finally, I will put these experimental results in the context of ongoing planetary science sample return missions, including NASA OSIRIS-REx and JAXA Hayabusa2.

Mount Tamalpias Astronomy Lectures

Gravitational Lensing: Bends in Spacetime – Livestream

One hundred years ago, Einstein predicted that light rays would bend in the space near a massive object – much as light rays refract in an optical lens. Today, we use this fact to weigh galaxies, to discover planets of other stars, and to “see” invisible black holes. How did this idea of gravitational lensing come about, and how do we use it today to probe all fields of astrophysics?

San Mateo County Astronomical Society

Resolving the Local Universe with the JWST & Hubble – Livestream

In his talk, Dr. Weisz highlights the amazing science and images produced by Hubble observations of local galaxies from the past three decades. The pinnacle of these studies is the Panchromatic Hubble Andromeda Treasury (PHAT) program, an 800-hour Hubble survey of our sibling galaxy Andromeda, and one of the largest Hubble programs ever conducted. Dr. Weisz will describe the PHAT survey and its scientific impact and discuss plans for the James Webb Space Telescope, which will succeed Hubble as the most sensitive telescope in existence following its launch in 2021.

Speaker: Dr. Dan Weisz, UC Berkeley
