DiRAC & Astronomy on Tap Seattle Present: ASTRONOMY AT HOME

Join us for an evening with an astronomer and participate in talks and live conversations about topics that vary from searching for the most mysterious stars in our Galaxy to the Starlink satellites changing our view to the night sky!

UW astronomers will talk about their work and latest discoveries. Astronomy at Home talks are for everyone: astronomy enthusiasts, students, and all who are curious and interested in astronomy and data science in astronomy. The talks will be 20 minutes in length with plenty of time for Q&A. All talks are streamed on YouTube and you can join for live discussion via Zoom.

Tune in on March 11th 2021 at 7:00pm

March 11, 2021 | Denis Vida | The Global Meteor Network – a planet-sized scientific instrument

Millimetre-sized dust particles from meteor showers move at hypervelocity speeds and can have kinetic energies comparable to a rifle bullet. Accurate predictions of meteor shower activity are essential for keeping satellites and astronauts safe from meteoroid impacts. These predictions heavily rely on models which use previous observations of meteor shower activity. Historically, observations of meteor showers were done visually (by eye) and data collected in that way are often unreliable and incomplete. The Global Meteor Network seeks to build a world-wide decentralized scientific instrument – a collection of highly sensitive low-cost meteor cameras running open-source software that are hosted by amateur astronomers. Currently, more than 250 automated meteor systems in over 20 countries produce hundreds of high-quality meteor orbits a day which are publicly available in near real-time. The data quality is ensured through automated calibration and by using advanced methods of meteor trajectory estimation.

Denis Vida is meteor physics postdoctoral researcher at the University of Western Ontario, Canada. Software engineer turned astronomer. His main interests are the physical properties and dynamical characteristics of meteoroids and minor bodies of the Solar System.
