Ben Tofflemire, Graduate Student in the Department of Astronomy at UW-Madison, explains how single stars form and why planets form around the stars. Tofflemire discusses the formation of pairs of stars, or binary stars, and the role of planets in binary star systems.
Anna Williams, Graduate Student in the Department of Astronomy at UW-Madison, explores the beginnings of magnetic fields in galaxies and galaxy clusters by studying the magnetic fields on Earth.
Edward Churchwell, Professor Emeritus, Department of Astronomy at UW-Madison, explores how the universe has changed from its beginnings to the present time and envisions what it might be like in the distant future.
Kyle Cudworth, Professor Emeritus of Astronomy and Astrophysics at the University of Chicago, explains the difference between open star clusters and globulars, which contain hundreds of thousands of stars and are more centrally concentrated than the open clusters.
Christy Tremonti, Assistant Professor in the Department of Astronomy at UW-Madison, discusses where chemical elements come from and how they are distributed throughout the universe. Tremonti explains how life is influenced by common chemical elements in the universe.
Alex Lazarian, Professor in the Department of Astronomy at UW-Madison, provides a history of magnets beginning with their use by fortunetellers and Vikings. Lazarian explains how magnetic fields work and discusses how we obtain information about astrophysical magnetism.
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.
