Eta Carinae, is a well known massive, luminous star system located about 7,500 light-years away from the Earth. It is in the southern constellation of Carina, and produced an outburst in the 19th century making it the second-brightest star in the sky. Since then, Eta Car has been well studied but still it holds fascination for astronomers studying explosive star systems. It has two massive stars that come very close to each other every 5.5 years. The system has intense outflows which accelerate charged particles to an amazing speed and can produce energy bursts that can be observed by many telescopes. Studies with the NuSTAR space telescope recently have helped characterize the outbursts and the types of particles sent our way

Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on July 12 at 3PM Eastern time as they discuss with the investigators, including Kenji Hamaguchi of Goddard Space Flight Center (GSFC) and U. of Maryland (UMBC), Michael Corcoran of GSFC and Catholic University, and Christopher Russell (Pontificia Universidad Católica de Chile) about how they probed Eta Car with NuSTAR to understand the system, and they will describe this interesting NASA mission that probes the high energy universe.

Enjoyed today's Hangout! AAS published a book, "Humans and Machines in Space: The Payoff" in 1992. I was the editor, in collaboration with Gen. James Abrahamson. We are both now interested in re-publishing with additional updated reference (such as related to today's discussion), if AAS is willing and able. As Gen. Abrahamson stated in his concluding remarks, "The rich experiences of our past will serve us well in meeting this challenge of the future!"
