Afternoon Astronomy Coffee Hangout 28 September

"A Nova Rediscovered after 600 Years"

The diligence of experienced star gazers can stand the test of time — in this case, 600 years later. Korean astrologers in Seoul almost 600 years ago observed a bright new star in the tail of the constellation Scorpius. They monitored it for 15 days, but then it faded from view. A new look by astronomers today considered the observations of the Royal Imperial Astrologers. They determined this transient star was an outburst called a nova explosion. A recently published study discusses the new data suggesting that observation from the 1930s signaled the presence of a small scale “dwarf nova” which undergoes periodic eruptions. This means that some of these objects can erupt and then fade for hundreds even thousands of years before being seen again.

Join regular hosts Tony Darnell and Carol Christian on Thursday, 28 September, at 3:00 pm ET as they chat with Michael Shara (American Museum of Natural History) and collaborators about how this object was found and what the new analysis indicates about it. The best place to hangout with us will be on YouTube, broadcast on the Deep Astronomy Channel. The direct link to view this hangout will be posted on the Deep Astronomy Facebook page. During the hangout, you can take part in the live chat and join the conversation on Twitter with #AstroCoffee. An archive of previous hangouts in this series may be found in the Deep Astronomy YouTube playlist.

Afternoon Astronomy Coffee

What Are "Afternoon Astronomy Coffee" and "Future in Space" Hangouts?

"Future In Space” and "Afternoon Astronomy Coffee" Hangouts are part of a weekly series, held every Thursday, that also includes a segment called "Footsteps to Mars." We bring the the latest research in astronomy, highlights from the future of space astronomy and astronautics planning, as well as updates on the exploration of Mars to you every week via Hangouts on Air. With the sponsorship of both the American Astronomical Society (AAS) and the American Astronautical Society (the other AAS), our hosts Tony Darnell, Carol Christian, Alberto Conti, and Harley Thronson examine today's breakthroughs in research and peer into the unfolding possibilities of what we may learn about the universe and Mars exploration. We join with members of the American Astronomical Society to chat, in an informal online setting modeled after "science coffee" events held in universities and research organizations across the country. We will examine what we hope to learn about exoplanets, black holes, the early universe, quasars, and life in the universe along with what technologies might help us — and reflect upon the scientific endeavors occurring today that uncover amazing astrophysics and lay the groundwork for studies to come.

We will also explore the technology and engineering used today as well as possibilities for future space travel and research with members of both societies, and probe what our future in space may look like and how we might get there. We will examine the underlying technologies of space telescopes, orbiters, landers, and human space vehicles now and in the years to come. We will delve into topics that help us understand the possibilities and limitations of human space flight and eventual human colonization of other worlds.

We hope you can join us each month as we bring experts from both societies — people who think about and plan for our future in space — to your computer, tablet, or smartphone. We invite you to bring your questions and comments and get ready to learn about the amazing possibilities for the future of space astronomy and exploration.
