The Looking Glass Universe – From Baryogenesis to Biogenesis

Is there a connection between the excess of matter over antimatter and handedness in biology?

The laws of physics were long thought to be unchanged when viewed in a mirror.
We have known for over sixty years that they are not.
As Sakharov first explained, this asymmetry, in action during the first moments of the universe, may account for the prevalence of matter over antimatter today.
Likewise, as Pasteur first showed, the laws of biology are similarly asymmetric, as is exhibited by the structure of DNA.
In this talk I will discuss how there might be a causal connection between these two qualities, mediated by cosmic rays.
On the way, I will illustrate this uneven-handedness using recent, exciting, astronomical discoveries, involving black holes, neutron stars and exoplanets.

Roger Blandford took his BA, MA and PhD degrees at Cambridge University. Following postdoctoral research at Cambridge, Princeton and Berkeley he took up a faculty position at Caltech in 1976 where he was appointed as the Richard Chace Tolman Professor of Theoretical Astrophysics in 1989. In 2003 He moved to Stanford University to become the first Director of the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) and the Luke Blossom Chair in the School of Humanities and Science. His research interests include black hole astrophysics, cosmology, gravitational lensing, cosmic ray physics and compact stars. He is a Fellow of the Royal Society, the American Academy of Arts and Sciences, the American Physical Society and a Member of the National Academy of Sciences. In 2008-2010, he chaired a two year National Academy of Sciences Decadal Survey of Astronomy and Astrophysics. He was awarded the 1998 Dannie Heineman Prize of the American Astronomical Society, the 2013 Gold Medal of the Royal Astronomical Society, the 2016 Crafoord Prize for Astronomy and the 2020 Shaw Prize for Astronomy.

NASA’s Juno Mission to Jupiter

Juno’s principal goal is to understand the origin and evolution of Jupiter. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars. With its suite of science instruments, Juno is investigating the interior structure, mapping Jupiter’s intense magnetic field, measuring the distribution of water and ammonia in the deep atmosphere. JUNO is also the first spacecraft to fly over Jupiter’s aurora and measuring both the energetic particles raining down on the planet and the bright “northern & southern lights” they excite. A huge bonus is the small public outreach camera that is taking fantastic images of Jupiter’s beautiful clouds. The images – some science, some art – are processed and shared by the public around the world. NASA’s JUNO mission was launched in August 2011 and has been in orbit over Jupiter’s poles since 4th July 2016.

Dr. Fran Bagenal is a research scientist and professor at the University of Colorado, Boulder and is co-investigator and team leader of the plasma investigations on NASA’s New Horizons mission to Pluto and the Juno mission to Jupiter. Her main area of expertise is the study of charged particles trapped in planetary magnetic fields and the interaction of plasmas with the atmospheres of planetary objects, particularly in the outer solar system. She edited the monograph Jupiter: Planet, Satellites and Magnetosphere (Cambridge University Press, 2004).

Born and raised in the UK, Dr. Bagenal received her bachelor degree in Physics and Geophysics from the University of Lancaster, England, and her doctorate degree in Earth and Planetary Sciences from MIT (Cambridge, Mass) in 1981. She spent five years as a postdoctoral researcher at Imperial College, London, before returning to the United States for research and faculty positions in Boulder, Colorado. She has participated in several of NASA’s planetary exploration missions, including Voyager 1 and 2, Galileo, Deep Space 1, New Horizons and Juno.
