Dr. Sako is currently hunting for the putative giant planet -- Planet Nine -- that might be lurking in the outskirts of our Solar System. Planet Nine, if real, could be as large as ten Earth masses, but will only appear as a faint little dot due to its vast distance from the Sun. Dr. Sako and students use supercomputers to sift through the many millions of detections and background stars, galaxy, and other minor bodies in the solar neighborhood. Its discovery and nature will teach us about the history and formation of our Solar System. Masao Sako is an astrophysicist using large telescopes, supercomputers, and big data to study the Universe. He is the recipient of numerous teaching awards at the University of Pennsylvania, including the Lindback Award for Distinguished Teaching and the Dean’s Award for Innovation in Teaching. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
Do aliens walk among us? Have we been visited before? Are they out there watching… listening…studying us? And if they are out there, where might ‘there’ be? Our Milky Way can be a nasty and inhospitable place for life to develop, but all is not lost. There are some very unique and special places hidden amongst this hostile environment where the building blocks for life might be just right for extraterrestrial life to flourish. Brad Gibson is a Professor of Astrophysics. He completed his MSc and PhD at the University of British Columbia, building the world’s first Liquid Mirror Telescope Observatory. He was responsible for using exploding stars to determine the expansion rate of the Universe (as part of the Hubble Space Telescope Key Project), for which his team was awarded the Gruber Prize in Cosmology. Clearly a busy guy, he also discovered the first evidence that our own Milky Way’s nearest neighbours were being cannibalised by our Galaxy. Who better to answer the question: alien worlds and extraterrestrial life – where are they?!

Arlie O. Petters is a professor of mathematics, physics, and business administration at Duke University. Petters was born in a poor, rural community in Belize. At the age of 13, he emigrated to Brooklyn. He participated in an accelerated B.A./M.A. program at Hunter College, receiving his degrees in mathematics and physics in 1986. In 1991, he received his Ph.D. in mathematics from MIT. Petters' research is focused on the development of mathematical theory of gravitational lensing. He is the leading author of the book, /Singularity Theory and Gravitational Lensing/. Petters also works within Duke University's Fuqua School of Business, where he deals with finance, social entrepreneurship, and environmentally sustainable STEM business efforts. Petters has given back to the minority community by mentoring numerous underrepresented minority students, faculty, and professionals. He is highly involved in the Belizean community. In 2005, Petters founded the Petters Research Institute, which works to aid Belizean individuals pursuing work in STEM fields and aiding Belizean national development through environmentally sustainable applications of technology. In 2008, he was named by the Queen of England to Membership in the Most Excellent Order of the British Empire as a result of his exceptional work in research, education, and outreach. In 2010, he was appointed as the Chairman of the Council of Science Advisors to the Prime Minister of Belize. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Following more than a decade of international and national planning and an intense week of on-ice weather delays, Priscu led the field team successfully drilled through the overlying ice sheet and sampled directly the waters and sediments of a lake hidden beneath the Antarctic ice sheet. The groundbreaking exploration of Antarctica's subglacial environment marks the beginning of a new era in polar science, opening the window for future interdisciplinary scientific investigations of one of Earth's last unexplored frontiers.
