ESA / About Us / ESAC

As part of the ESAC Science Seminar Programme, this week our invited speaker is Jackie Faherty, from  the American Museum of Natural History of New York, USA.  Jackie is a world expert on citizen science, data visualization, dissemination, outreach and educational activities in space science, and she will give the seminar  'Visualizing a billion stars for science and education'

In this talk, Jackie Faherty will review how the European Space Agency's second catalog of the Gaia mission (Gaia DR2) is revolutionizing astronomy. Arguably all scientific questions can benefit from the nearly 1.4 billion parallaxes and proper motions, over 7 million radial velocities, photometric data in Gaia’s three bands (G, R, and B), variability information, and effective temperatures for a subset of objects. The Gaia results provide a unique opportunity for astronomers, data visualizers, and educators. Stellar positions and velocities enable us to map the Milky Way and examine the dynamics of stellar streams, co-moving companions, hypervelocity stars,  nearby moving groups, and solar system encounters.  From a visualization perspective, real time rendering of Gaia data is a challenge. 

During the presentation, Jackie Faherty will show the results of the visualization efforts with the Gaia catalog currently on-going at the American Museum of Natural History.  The visuals generated for this talk isolate scientifically rich data and stories, which can lead to scientific discovery and will illuminate Gaia data for students, teachers and the general public.
