Due to the snow and worsening road conditions, this public lecture has been postponed and will be rescheduled at a later date TBD.
The ultraviolet (UV) portion of the electromagnetic spectrum provides some of the most powerful diagnostics to shape our understanding of stars, planets, galaxies, and all the material in-between, but it has long been one of the most difficult regions to explore. The principal go-to observatory for astronomers is the venerable Hubble Space Telescope—the most sensitive ultraviolet eyes into the universe we have ever known. NASA is now studying a behemoth space observatory as a potential successor to Hubble to answer the pressing questions of the future, the Large UltraViolet/Optical/InfraRed Observatory (LUVOIR). At a massive 50 feet in diameter, LUVOIR would be more than 40 times larger than Hubble and 150 times more sensitive, but it’s more than a decade from being built.
Recent advances in technology have opened up a new and perhaps unexpected dimension in UV space astronomy that will fill the gap between Hubble and a possible LUVOIR: small satellites. At sizes ranging from a shoebox to a mini-fridge, these tiny spacecraft have the potential to do science that is exceedingly difficult even for Hubble, and outside the capabilities of other space astronomy missions.
In this talk, Dr. Brian Fleming will tell us what has changed to make a shoebox satellite suddenly have outsized potential, and highlight some exciting science that will be carried out by LASP scientists with the first batch of astrophysics CubeSats in the coming years.
