Learn about the second industrial revolution as Karun Thanjavur demonstrates the amazing power of artificial intelligence. The future is here today!
Abstract: Artificial intelligence (AI), specially Deep (Machine) Learning applications are already ubiquitous in everyday use, and have been called the second industrial revolution. Deep Learning algorithms, called Neural Networks, thrive on Big Data, the happy ‘problem’ we now face of enormous amounts of data available in astronomy and in almost all fields of human endeavour. Piggybacked on the impressive recent advances in high performance computing, neural networks are trained on these available large datasets to then perform a variety of human-like tasks, such as realtime decision making, identifying subtle patterns in the data, forecasting, making recommendations based on experience, and so on. In this presentation I aim to provide an overview of this rapidly burgeoning field, explain in simple terms the construction and working of a neural net, and illustrate these principles with a few examples drawn from literature and from my own research.
How to Talk to a Science Denier:
Jim Hesser attended a recent UVic Physics colloquium by Dr. Lee McIntyre (Boston U.) was on the topic, “How to Talk to a Science Denier: What I learned at the Flat Earth Convention”.
Jim reports that the key take away message was that the best way he’s found to help a science denier is through real conversation that leads to building a relationship of trust between the denier and the scientists; once there is trust, the stage is set for the denier to look at alternate views and evidence the scientist provides. People interested in the science denial challenge might enjoy exploring this presentation.

A Perimeter Institute Public Lecture on WEDNESDAY, OCTOBER 7 at 4 pm PDT
What do data science and the foundations of quantum theory have to do with one another? A great deal, it turns out.
Causal inference is a branch of data science that focuses on a common problem across many disciplines: disentangling correlation and causation in statistical data. Meanwhile, quantum physicists have pondered this problem as part of a continuing effort to make sense of puzzling quantum phenomena.
In the first talk of Perimeter’s 2020/21 Public Lecture Series, Robert Spekkens and Elie Wolfe will explore what is happening at the intersection of these two fields and how thinking like a quantum physicist leads to new ways of separating cause and effect from correlation patterns in statistical data.

Impressive Images of Mars from Edmonton RASCal Abdur Anwar
Abdur Anwar dusted off his old Celestron 8 inch Schmidt Cassegrain Telescope and put it to good use using a lucky imaging technique to capture some amazing images of Mars. On August 25th Abdur experimented with the program WinJupos which can remove the blurring effect caused by rotation. Check out the before and after images below.
Speaking of Mars check out this 4K video
The video in this link displays a collection of high resolution images taken on a number of Martian space missions. It is 12 minutes well spent.
Hawaiian Nights: A Personal Journey from Vancouver Island to Maunakea, with Cam Wipper
Don’t miss this interesting Zoom presentation at 4:00 PM PDT on Friday August 28th. Growing up in Nanaimo, Cam never imagined he would spend nearly a decade living in Hawai’i and working on Maunakea, the best place on Earth for astronomical observations.
In his talk, Cam will tell the story of how he found himself on Maunakea, from his days as a student at Vancouver Island University, to his first night up on the summit of Maunakea, nearly 14.000 feet (4200m) above sea level. This will include a brief history of astronomy in Hawaii, as well as an exploration of how a modern astronomical observatory conducts scientific observations. All will be told from the perspective of a telescope operator and scientific observer; a position Cam has held at the Canada-France-Hawaii Telescope since 2015. Click here to register.

A Poetic Pelican by Doug MacDonald
A wonderful bird is the Pelican. His beak can hold more than his belly can. He can hold in his beak enough food for a week! I’ll be darned if I know how the hellican.
Dixon Lanier Merritt
Shot this Aug. 9 – 13 with Bortle 6 skies. This bird lives in Cygnus, not too far from Deneb. I processed it in the SHO palette; it represents just over 8 hours of narrowband exposure with a 5″ refractor at f/5.5.
Final UVic Open House of the Summer is a Block Buster!
Cosmic Collisions Abstract: What happens when galaxies collide? Right now, the Andromeda Galaxy is hurtling towards us, on a direct collision course with our galaxy. Surely the Milky Way will not escaped unscathed? For almost a century astronomers have been trying to figure out what happens when galaxies clash, and from that investigation a harrowing tale of starvation, cannibalism, and complicated acronyms has arisen. With today’s massive telescopes and high-tech simulations, we can hope to understand what happens when the largest objects in the Universe go face-to-face. And perhaps we can predict how our galaxy will be changed for the better (or the worse)

Press Briefing on Starlink and other mega-constellations
At 11AM on Tuesday August 25th the American Astronomical Society (AAS) and NSF’s NOIRLab will have a press briefing on the SATCON1 LEOsat mega-constellations workshop report. SATCON1 gathered astronomers, satellite operators, dark-sky advocates, policy makers, and other stakeholders to discuss, understand, and quantify the impacts of large satellite constellations on ground-based optical and infrared astronomical observations as well as on the human experience of the night sky. The briefing will be live-streamed on the AAS Press Office YouTube channel (https://www.youtube.com/c/AASPressOffice)
Edmonton RASCal Abdur Anwar Captured the Cacoon and Bubble on August 9th
Abdur writes: Finally had a clear night last week and I spent most of my imaging time on the Cacoon Nebula (IC 5146) and the Bubble nebula. I got about 2 hours of data on the Cacoon and about 1.5 hours on the Bubble nebula using an ASI1600mm and an 8″ reflector. Really happy with how they turned out 🙂
Equipment and capture details for each target in order: ASI1600MM Pro ZWO LRGBHa filters Ha: 12 mins (Cacoon) / 27 mins (Bubble nebula) RGB: 20 mins each / 10 mins each L: 60mins / 30 mins Scope: 8″ f3.9 reflector Mount: EQ6R Pro
Dan writes: “Thanks to Bill kindly hosting last night, as the conditions at Pearson provided that opportunity I have been waiting for. The result isn’t perfect but that just means I’ll need to revisit in the future; I know where I need to be to take a longer stab at this target next year. This is 48.5 minutes (97x30s) using my Sigma 105 at f1.4 and my Canon Ra at iso 640.”
Title: Peering Into the Darkness with the JCMT: Witnessing the Birth of Stars
The birth of stars remains shrouded in mystery. Stars form inside thick puddles of gas and dust located primarily along the spiral arms of the Galaxy. Astronomers use infrared and radio telescopes to peer into and through these murky puddles to witness the birth of stars. For over 25 years the JCMT has been leading investigations to uncover the formation of stars in the Galaxy. In collaboration with the Spitzer Space Telescope, the Herschel Space Observatory, and the ALMA Observatory in Chile, the JCMT has transformed our understanding of stellar birth. Join me on an adventure to uncover nearby stellar nurseries.

Some Great Planetary Detail
Lucky Imaging of Planets and the Moon
If you want to learn how to capture wonderful images like the above perhaps you should attend the following webinar!
Tuesday, August 11th – 7:00pm ADT / 6:00pm EDT / 3:00PM PDT Nova East 2020 – Lucky Imaging: Astrophotography of the Moon and Planets Lucky imaging is a technique used to capture high resolution images of the Moon and planets. It involves taking as many images as possible, often several thousand, with a high-speed “video” camera and using specialized software to identify and stack only the sharpest images. The talk, presented by David Hoskin, will cover the equipment, software and processing workflow used in lucky imaging.
Edmonton RASCal Mark Zalik – captured this remarkable sequence on August 4th which closely resembles hummingbirds. All Edmonton content kindly relayed by Dave Robinson. Mark writes: Wonderful NLC display tonight! Nice arrays of billows formed way down near the horizon, where the twilight imparted a beautiful cinnamon colour on the NLC. A bit earlier in the display, the clouds formed an ethereal hummingbird.
