John Chisholm, Graduate Student in the Department of Astronomy at UW-Madison, discusses the life cycle of galaxies. Chisholm explores the processes that make galaxies grow when young and fade out as they age.
Andreas Velten, Assistant Scientist, Laboratory for Optical and Computational Instrumentation, UW-Madison, introduces an imaging system which sends laser pulses from a lunar satellite to the entrances of caves on the moon. Analysis of the light “echo” from the caves provides images of the interiors and helps scientists to determine which of the caves could be explored with a lunar rover.
Tim Wagner, Assistant Researcher, Space Science & Engineering Center, UW-Madison, discusses two new surface-based weather forecasting systems in development. The first is a network of instruments which can be located on the roof and the second is a mobile trailer which can be driven to record the weather up close.
Jim Lattis, Director, UW Space Place, follows the New Horizons spacecraft, launched in 2006, as it makes its closest approach to Pluto. Lattis shares close-up images of the dwarf planet and discusses the scientific observations resulting from the mission.
Brenna Holzhauer, Director of Exhibits, Aldo Leopold Nature Center, Madison, explores how to talk about the local effects of climate change and global warming with your children, students and families. Holzhauer discusses the basic science surrounding climate change and simple changes that can help the environment.
Jay Gallagher, Professor, Department of Astronomy, UW-Madison, celebrates the 25th anniversary of the Hubble Space Telescope and explores its Wisconsin connection.
Stephen Pardy, Graduate Student, Department of Astronomy, UW-Madison, explains that with the appropriate ingredients: hydrogen gas, stars and dark matter, the laws of physics and evolution, you can create a galaxy.
David Liebl, Faculty Associate, College of Engineering, UW-Madison, discusses weather, Wisconsin’s climate, the projection for the future of our climate, and how we’re using satellite remote sensing capabilities to observe climate change impacts on the state.
Jim Lattis, Director, UW Space Place, examines the part UW astronomers played in a major re-evaluation of the size of the Milky Way between 1930 and 1936. The astronomers established which key features determined our modern concept of a galaxy.
Jean Creighton, Director, Manfred Olson Planetarium, UW-Milwaukee, reflects on her selection by NASA to fly on the Stratospheric Observatory for Infrared Astronomy (SOFIA). Creighton was one of 24 teachers chosen to observe the earth’s atmosphere from 40,000 feet.
