A Universe of Surprises - Livestream

Our universe is full of surprises, from ghost remnants of black hole jets to exotic planets around distant stars to Boyajian’s star, the most mysterious star in our galaxy. How scientists do cope with surprises? What is it like to think you might have found aliens? And how might you too make a remarkable discovery from the comfort of your home?

Speakers: Chris Lintott and Laura Trouille, Zooniverse

The Drake Equation: Livestream

At the heart of the Search for Extraterrestrial Intelligence (SETI) lies the Drake Equation, a mathematically simple yet fascinatingly enigmatic formula proposed by American astronomer and SETI founder Frank Drake. The Drake Equation provides a way to estimate the number, N, of advanced civilizations present in our Milky Way galaxy. Although N is often assumed to be large - there would be many civilizations in the Galaxy -, large numbers for N are in apparent conflict with observation, a contradiction known as the Fermi Paradox, named after Italian-American physicist and 1938 Nobel Prize winner Enrico Fermi. 

Pascal Lee, planetary scientist at the SETI Institute, examines the state-of-the-art of our knowledge about each term of the Drake Equation, and reaches the perhaps surprising conclusion that N might actually be a very small number, close to 1. We could be it. The implications of N~1 are profound and will be discussed.

Mount Tamalpias Astronomy Lectures

Oumuamua: Interstellar Visitor - Livestream

In 2017, astronomers detected an elongated object swinging past Earth on its way out of the solar system. The size, shape, and motion of Oumuamua (roughly “scout” in Hawaiian) inspired a few excited researchers to suggest the visitation of an interstellar “spaceship." This presentation will explore the physical nature of Oumuamua and a vast fleet of its extrasolar cohorts.

SETI Talks: Could Rogue Planets Harbor Life? - Livestream

Life elsewhere in our galaxy may come in many exotic forms, and scientists have speculated about the existence of life on alien worlds, like rogue planets. Rogue planets are planets that are not orbiting any stars.

It’s awe-inspiring that astronomers have discovered more than 4,000 confirmed exoplanets to date (and thousands of more exoplanet candidates). However, most detection techniques rely on the existence of a host star. To detect rogue planets, astronomers use gravitational microlensing, which involves watching foreground objects pass in front of distant background stars. The chances of such an event are slim, but modern astronomers observe tens of millions of stars every 15 minutes, which will increase to 100 million with the Nancy Grace Roman Space Telescope, to detect them. Based on planets that have already been found, our Milky Way could have 50 billion wandering planets, a staggering number that may imply that if life exists on those worlds, our galaxy is full of it.

If a planet is ripped from the warm environment of its star and drifts in the frigid depths of space, it could still hold on to a liquid ocean - and maybe life - beneath an icy crust. Could submarine aliens on such a planet have a chance at survival? And for how long?

We invited two astronomers to discuss the detection and characterization of rogue planets and their potential to harbor life. Dorian Abbot, an associate professor at the University of Chicago, co-authored a proposal for a habitable planet in interstellar space in 2011. And Matthew Penny, an assistant professor at Louisiana State University, leads the MISHAPS transit survey and numerous other microlensing focused programs.

Franck Marchis, a senior planetary astronomer at the SETI Institute, will host this conversation about the future of rogue planet detection and their potential to harbor life in many sorts of weird situations that we haven’t thought of before.

Fast Radio Bursts: ElectroMagnetic Pulses from Cosmologically Distant Neutron Stars with Hundred GigaTesla Magnetic Field? - Livestream

For over a decade, radio astronomers have been observing millisecond pulses of intense radio emission. They now appear to be associated with strongly magnetized neutron stars called Magnetars, where extreme quantum electrodynamic (QED) and plasma processes take place. The rapidly developing observational picture will be summarized and a plethora of theoretical models will be reported.The possibility that Fast Radio Bursts (FRBs) and pulsar radio emission are an expression of force-free electrodynamics, as originally developed by James Clerk Maxwell, will be discussed.

A Cosmic Perspective: Searching for Aliens, Finding Ourselves - Livestream

Are we alone? Humans have been asking this question throughout history. We want to know where we came from, how we fit into the cosmos, and where we are going. We want to know whether there is life beyond the Earth and whether any of it is intelligent.

Since the middle of the twentieth century we have had tools that permit us to embark on a scientific exploration to try to answer this old question. We no longer have to ask the priests and philosophers what we should believe about extraterrestrial life; we can explore and discover what’s actually out there. Our tools are getting ever better. We have discovered extremophiles in the most unexpected places on this planet and we have discovered that there really are far more planets than stars out there. We haven’t yet found life beyond Earth, but there is currently a debate about the detection of Phosphine in the clouds of Venus, and whether this might imply biology. There is a vast amount of other potentially-habitable real estate to explore beyond our solar system, and there are many plans to do just that. The 21st century will be the century in which we will find some answers, this will be your century.

As we look up and look out, we are forced to see ourselves from a cosmic perspective; a perspective that shows us as all the same, all Earthlings. This perspective is fundamental to finding a way to sustain life on Earth for the long future.
