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.

Until just a few decades ago, scientists weren't sure whether our Sun was the only star to host planets. Today, we know for certain it's not. Thousands of planets outside our solar system have now been found, from huge gas giants sizzling close to their stars to icy and watery worlds unlike any of our eight familiar planets. In the second episode of Infinity and Beyond, host Abigail Bollenbach takes you on a journey to other worlds beyond our own. Enjoy the ride!

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them.

For more than a decade, astronomers have searched for planets orbiting AU Microscopii, a nearby star still surrounded by a disk of debris left over from its formation. Now scientists using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope report the discovery of a planet about as large as Neptune that circles the young star in just over a week. The system, known as AU Mic for short, provides a one-of-kind laboratory for studying how planets and their atmospheres form, evolve and interact with their stars. AU Mic is a M-type red dwarf star at least 150 times younger than our Sun. It’s so young that a vast disk of dust and icy grains still surrounds it. The planet, AU Mic b, orbits very close to its star within a central zone where the disk material is cleared away. It's around 8% larger than Neptune, with no more than about 3.4 times its mass.

NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope have found a young Neptune-size world orbiting AU Microscopii, a cool, nearby M dwarf star surrounded by a vast disk of debris. The discovery makes the system a touchstone for understanding how stars and planets form and evolve.

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of. That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone. Thumbnail credit: NASA/Harvard-Smithsonian Center for Astrophysics/D.

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

Today, we discuss the possibility of humanity being alone in the galaxy or perhaps even the greater universe. We consider just how improbable our existence is by evaluating both the number of potential sites for life within our galaxy alone as well as the probability of abiogenesis occurring elsewhere. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://youtu.be/yyVJkbUbzxY Music: “Cylinder Five” by Chris Zabriskie “Cylinder Eight” by Chris Zabriskie “Stories About the World That Once Was” by Chris Zabriskie
