Afternoon Astronomy Coffee Hangout on 30 March

Tuesday, March 28, 2017 - 14:33

"Monster Black Hole Gets Kicked Out of Home Galaxy by Gravitational Wave"
Afternoon Astronomy Coffee Hangout

What happens if two black holes collide? Scientists have found evidence that such an event took place during the merging of two galaxies. The result? New observations show that a monster black hole was actually ejected from such a collision site, being given a kick from gravitational waves from the collision. The amount of energy required is enormous! Probably the equivalent energy of 100 million supernovas exploding simultaneously. Observations show that the runaway black hole is the most massive ever found so distant from its origin.

Join regular hosts Tony Darnell and Carol Christian on Thursday, 30 March, at 3:00 pm ET as they chat with Marco Chiaberge (Space Telescope Science Institute), Eileen Meyer (University of Baltimore, Baltimore County), and Grant Tremblay (Yale University) about the discovery and observations of this remarkable event and how they arrived at the exciting result that the black hole was kicked out with gravitational waves. The best place to hangout with us will be on YouTube, broadcast on the Deep Astronomy Channel. You can also RSVP on the Facebook event page, 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 a Deep Astronomy YouTube playlist.

Afternoon Astronomy Coffee Hangout 30 March


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 on 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 cooperation 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 bring you topics that examine today's breakthroughs in research and look forward to 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.
