'Oumuamua: A Mysterious Interstellar Interloper Dr. Amaya Moro-Martin, Space Telescope Science Institute During the formation of our solar system, a tremendous number of asteroids, comets, and planetesimals were ejected into interstellar space by gravitational encounters. If extrasolar planetary systems, which are now known to be quite common, experienced a similar development, then our galaxy should be teeming with these expelled objects. Astronomers were perplexed that none had been found passing through our solar system. Then, in 2017, the discovery of ‘Oumuamua transformed the situation from puzzlement to bewilderment. Observations with a wide range of telescopes followed the brightness and trajectory of this first interstellar interloper but left important questions about its origin and composition unanswered. Further, what process was responsible for the non-gravitational acceleration found in its unbound orbit? This cosmic visitor will not return to provide explanations. Thus, the intriguing inquiries ‘Oumuamua left behind will remain as we seek out and study other guests from beyond our solar system.

Astronomy Night at the David Dunlap Observatory - ONLINE, July 4, 2020 (All Welcome) Extraordinary Exoplanets with Emily Deibert, PhD candidate at University of Toronto Over 4000 exoplanets have been discovered to date—but what do we really know about them, and how do we know it? Join Emily Deibert in exploring the main methods and missions that have been used to discover the diverse population of exoplanets throughout our Galaxy, and learn about some of the most extraordinary exoplanets we've found so far. She will also discuss how astronomers are starting to learn about what conditions on these exoplanets might be like, and highlight some of the advances we hope to make in the field over the next few years. Emily Deibert is a PhD candidate and Vanier Scholar in the Department of Astronomy & Astrophysics at the University of Toronto. Her thesis focuses on observing exoplanet atmospheres with large, ground-based telescopes around the world. Emily also works as a freelance science writer, and likes to spend her free time reading.

This lecture is part of the free and open to the public lecture series for the Royal Astronomical Society's bicentenary celebrations in 2020. How did our Galaxy form? Is there only one way to form a spiral galaxy like ours, or can they form in different ways? And what role does the mysterious dark matter play in galaxy formation? One way to address these key questions is through the forensic, star-by-star analysis of nearby galaxies. By treating each star as a fossil of galactic evolution, we can piece together a road-map for how the beautiful spiral galaxies of the Universe are produced. In this talk, I’ll discuss what we know about the formation and evolution of the Milky Way and Andromeda, and how Galactic Archaeology can help us better understand the formation of all spiral galaxies.

Professor Lisa Kaltenegger, Director of the Carl Sagan Institute, provides an overview of exoplanet science. How close are we to identifying signs of life on rocky exoplanets? What challenges must be overcome to discover whether we are alone in the Universe? Credit: American Astronomical Society 236th Meeting - Fred Kavli Plenary Lecture

Prof. Sir Martin Rees (Institute of Astronomy, Cambridge) Title: Progress and frustration in Cosmology Abstract: It is gratifying that some of the key numbers describing our Universe have been measured to a precision of a few percent. We are learning about the emergence and properties of galaxies, stars, planets and life -- and how this chain of events depended on these numbers. These advances have sharpened up new mysteries. Some of these will be clarified by new observations; others, such as the overall scale of the universe (and whether we inhabit a multiverse) are likely to prove frustratingly intractable.

Once a month, SAGANet (www.saganet.org) and the NASA Astrobiology Program host a program called "Ask an Astrobiologist", where the public is invited to interact with a high-profile astrobiologist, who replies to Twitter, Facebook, and chat questions live on video. Each session lasts about an hour. Hosted by Dr. Graham Lau (Blue Marble Space Institute of Science) Featured Guest: Dr. Eddie Schwieterman (University of California, Riverside) Directed by Mike Toillion (NASA Astrobiology Program) Illustrations by Aaron Gronstal (NASA Astrobiology Program) Music & Animation by Mike Toillion (NASA Astrobiology Program)

Night Sky Network members enjoyed a webinar on June 16, 2020 hosted by Bruce Pittman from NASA's Space Portal Office, who shared the present, and future of commercial ventures in space. A quiet revolution has been taking place in the development of space over the last 20 years. Sparked by the space ambitions of men such as Jeff Bezos and Elon Musk, these efforts will come into full display over the next 42 months starting with the launch of the NASA Commercial Crew Demo 2 mission by SpaceX now scheduled for May 27th and hopefully ending with Amercians returning to the lunar surface for the first time in 50 years by December 2024. But this story is about more than just getting to space. We will also talk about the start of a space manufacturing revolution that is now beginning on the International Space Station. It has been said that the first trillionaire will be made in space, it may be one of the people that we will talk about. About Bruce Pittman Bruce Pittman is the Director of Commercial Space Development at OffWorld Inc. and is currently working as a contractor in the Space Portal Office at the NASA Ames Research Center in Silicon Valley where he works as the Chief System Engineer. Bruce is a co-founder and Chief Space Officer for the not for profit Future Frontiers Institute. He is also the Senior Operating Officer and Senior Vice President of another non profit, the National Space Society. For more information about the Night Sky Network: https://nightsky.jpl.nasa.gov

your host, Shaun Fletcher will discuss equipment, imaging techniques and processing of planetary images.  Note that there is NO 8pm LIVE STREAM tonight as the AAS meeting tonight is in the planetarium which doesn’t lend itself well for filming

Gibor Basri (University of California, Berkeley) chats about the AAS Journal article on starspot light curves, and where we can go from here given the published article. Article: "Calibration of Differential Light Curves for Physical Analysis of Starspots" https://ui.adsabs.harvard.edu/abs/2018ApJ...865..142B/abstract Gibor's's web presence: https://astro.berkeley.edu/people/gibor-basri/ The intended audience for the AAS Journal Author Series is active researchers.

Part 2, The Shaping of the Space Age by Alan Bond | 14/04/2015

Cosmic Coffee explores a different topic in astronomy or planetary science each week. This week, Lowell Observatory Director Dr. Jeff Hall speaks with Larry Lang, Executive Director of the Flagstaff Symphony Orchestra, and Charles Latshaw, the orchestra's conductor. Together, they'll explore the symphonic sounds of space, such as "The Planets" by Gustov Holst. *This episode of Cosmic Coffee is sponsored by APS. Cosmic Coffee is presented each Thursday at 9am AZ/PT.
