SUMMARY:Worlds Revealed Speaker Series | Perturbation? Prediction\, Photographs and the search for Planet X
DESCRIPTION:Prediction\, Photographs\, and the Search for Planet X with Dr. Stephen Levine\nWhat did it take to find a new planet 96 years ago? And what else can we learn and do\, even today\, with those original search photographs and observations? \nThis talk will explore what might have prompted Percival Lowell to seek a planet out beyond Neptune. Progress in mathematics and computing combined with better telescopes and the relatively new photographic plate made possible large scale searches for things that moved across the sky. The technical advances alone were not enough; success required a degree of attention to detail and dedication as brought by researchers like Clyde Tombaugh. \nMany of the techniques used are still in use today in digital form. As we now digitize those original photographic images from 80 to 120 years ago\, we are finding new ways that they can help advance scientific studies and exploration of our solar system and the stars in our galaxy today. For example\, NASA had photographic plates taken at Lowell in the 1930s and 1940s scanned to help improve the trajectory for the New Horizons mission fly-by of Pluto in 2015.

SUMMARY:Worlds Revealed Speaker Series: Magnetic Mayhem
DESCRIPTION:Magnetic Mayhem: How Young Stars Make Life Difficult for Their Planets with Dr. Clara Brasseur\nIn this talk\, Dr. Clara Brasseur will explore the intense magnetic environments of young stars and how they dictate the survival of nearby worlds. While measuring a star’s surface is possible\, mapping its hot outer atmosphere (the corona) is a much greater challenge. Dr. Brasseur will share how her team used the surface of AB Doradus (a young star similar to an infant version of our Sun) as a blueprint to build a 3D model of its corona. \nBy comparing this model to real-world radio telescope observations\, they confirmed the existence of a massive “magnetic bubble” stretching 8 to 10 times the star’s width. Dr. Brasseur will discuss the exciting implications for habitability: since many planets orbit directly inside these high-energy bubbles\, their early exposure to this “magnetic mayhem” likely played a defining role in shaping their atmospheres and their potential to support life. \nClara Brasseur is a National Science Foundation Postdoctoral Fellow at Lowell Observatory. Her research focuses on cool stars and brown dwarfs\, specifically how radio telescopes can be used to detect magnetic fields in their atmospheres. She is also interested in stellar flares\, particularly in the ultraviolet. Beyond her research\, Clara is a dedicated astronomical software developer with a special interest in data sonification.

SUMMARY:Meet An Astronomer | Dr. Kathy Eastwood
DESCRIPTION:Meet An Astronomer | Dr. Kathy Eastwood\nHead up to the Open Deck Observatory on Saturday\, May 30 to meet astronomer Dr. Kathy Eastwood! \nTake a peek at real-time images of planets\, stars\, galaxies and other celestial objects to be displayed on a large television screen outdoors with our new MallinCam. This is your opportunity to see interesting objects in the night sky\, learn about an astronomer’s research\, and ask questions you might have about any topic in astronomy. This event is included with a general admission ticket.
