Dr. Brian Grefenstette, the NuSTAR Principal Mission Scientist at Caltech, will discuss NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, mission, in a virtual event on Thursday, May 26, starting at 7 p.m.

NuSTAR is the first space telescope capable of taking focused high-energy X-ray observations of the cosmos, providing unprecedented information on the dynamics of black holes, exploding stars, and the most extreme active galaxies.

NuSTAR has been in space for almost a decade.  At the event, Dr.  Grefenstette will explain how NuStar has changed the way one looks at the universe.

Hosting the discussion are Marc Razze, of NASA/JPL’s Public Services Office, and Kaitlyn Soares, Public Outreach Specialist at NASA/JPL.

The discussion is free to watch on YouTube. To watch, go to on the date and time of the event.
