BayAstro – Events of Week of 08/17/2020 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. Many thanks to Ken Lum, who created this event listing.
==================================
Due to concerns about the spread of the Coronavirus or COVID-19 virus, some events have been or may be cancelled. Many venues will be closed perhaps, into September. Other events may offer online links and connections. To check on the status of a given event, check their website for updates.

Perseverance: A Martian Rover to Find Life? – Livestream

The Mars 2020 Perseverance Rover successfully launched on July 30, 2020, is now en route toward Mars. The mission will pave the way for future human expeditions to Mars and demonstrates technologies that could be used by future Mars explorers.

Designed to search for signs of ancient microbial life, the robotic rover is equipped with an instrument that will drill to collect core samples of Martian rock and soil and then store them in sealed tubes for pick-up by a future mission. The Mars 2020 rover will include innovative technologies to explore the Jezero crater region, such as a Mars Helicopter that will become the first powered flight craft on the Red Planet and a sample caching system.

In anticipation of its landing, scheduled for Feb 18, 2021, we invited two SETI Institute researchers to discuss the potential of the mission to find evidence of microbial life and employ new techniques to explore Mars. Chemist and planetary scientist Janice Bishop studies spectral fingerprints of minerals and Mars analogs on Earth and is a member of the CRISM orbital spectroscopy team. Physicist and planetary scientist Pablo Sobron develops spectroscopic instruments for planetary exploration and is a member of the Mars 2020 Science Team. They will tell us how Perseverance will search for traces of past or present microbial life in chemical, mineralogical, or textural fingerprints. Perseverance is the first step towards investigating biology, not just chemistry on Mars through sample return. This talk will describe why Jezero Crater was selected for this mission, the types of investigations to be performed and what they expect the mission to discover.

Speakers: Dr. Janice Bishop, Dr. Pablo Sobron

Probing Fundamental Physics with Strong Gravitational Lensing – Livestream

In general relativity, the presence of matter can curve spacetime, and the path of a light ray will be deflected as a result. This process is called gravitational lensing, analogous to the deflection of light by (e.g. glass) lenses in optics.In rare and extreme cases, light can take different paths to the observer and more than one image of the source will appear.Strong gravitational lensing is lensing that is strong enough to produce these multiple images, arcs, or even Einstein rings. Many useful results for cosmology have come out of using this phenomena.Dr Birrer will shed more light on how astronomers are utilizing strong gravitational lensing to probe the nature of dark matter and dark energy, the dominant but yet unknown components of our Universe.

137 Years of Chabot Space & Science Center in 60 Minutes – Livestream

Chabot Space & Science Center has very old roots in Oakland and the East Bay, and no fewer than three incarnations as a student and public observatory and science education center. Now celebrating the 20th anniversary at its present location on the skyline of the Oakland Hills, the institution as a whole turns 137 this year. This presentation will trace and illustrate the rich and interesting history of an observatory that was, from its inception, dedicated to educating the public about science and the universe.

Speaker: Benjamin Burress, Chabot

Editor’s Note: This event is now listed for Friday, August 19, which is actually a Wednesday. The original listing was for Friday, August 21. The Facebook listing is for August 19.

Mapping the cloudy skies of a galactic black hole with the help of laboratory measurements – Livestream

High-mass X-ray binaries are binary star systems consisting of a supermassive star in orbit around an evolved compact object like a black hole or neutron star. Supermassive stars exhibit strong stellar winds consisting of material from the stellar atmosphere being ejected into space. These winds are unstable with a tendency to fragment into pockets of denser and colder material, referred to as clumps, embedded in tenuous hot gas. In high mass X-ray binaries, these winds are partially focused towards the black hole. As the material falls onto the black hole, energy is released in the form of radiation that allows us to ‘X-ray’ the stellar wind and its structure. Understanding the wind morphology and how it is impacted by the presence of the compact object is crucial for the evolution both of isolated supermassive stars and of these binary systems. In this talk, I will focus on the black-hole binary Cygnus X-1 and how we used laboratory measurements with an electron-beam ion trap to further our understanding of the clumpy wind in this system.

Friends of Mt. Tam Astronomy Night

Galactic Weather – Livestream

Just as Earth has an atmosphere, and stars (like the Sun) have coronas, galaxies are embedded in invisible halos of atomic gases. As galaxies evolve, these gaseous halos exhibit many interesting phenomena similar to rains and droughts on Earth. What do these enormous galactic climate systems look like, how are they studied, and how do they behave?

Speaker: Yong Zheng, UC Berkeley

This event was originally scheduled for July 25.
