Video: “Latest Exoplanet Results from NASA’s Kepler/K2 Mission”

Here’s an update on the latest exoplanet findings by the Kepler space observatory and a preview of the next generation of exoplanet search instruments: Latest Exoplanet Results from NASA’s Kepler/K2 Mission | SETI Institute

The all-sky TESS mission will soon revolutionize our view of planets transiting the nearest, brightest stars to the Sun, just as the four-year survey by NASA’s Kepler mission transformed our understanding of exoplanet demographics. Using the repurposed Kepler spacecraft, the ongoing K2 mission provides a natural transition from Kepler to TESS in terms of sky coverage, survey duration, and intensity of ground-based follow-up observations. For the past three years I have led a large, multi-institutional team to discover, follow up, validate, and characterize hundreds of new candidates and planets using data from K2. I will highlight some of our key results from the first two years of K2 data, and will conclude with a discussion of the path forward to future exoplanet discovery and characterization. 

 

Video: “NASA’s search for habitable planets and life beyond the solar system”

Here is a SETI Institute talk by Dr. Gary H. Blackwood of NASA JPL on NASA’s search for habitable planets and life beyond the solar system –

Dr. Gary H. Blackwood earned his BS, MS and PHD in Aeronautical and Astronautical Engineering from MIT. He has been an employee at NASA’s Jet Propulsion Laboratory in Pasadena, CA since 1988 and has worked on technology development for precision astronomical instruments and astrophysics missions including the Hubble Wide/Field Planetary Camera-2, the StarLight formation-flying interferometer, the Space Interferometry Mission and the Terrestrial Planet Finder. Since 2012 he has served as the Program Manager for the NASA Exoplanet Exploration Program, managed by JPL for the Astrophysics Division of the NASA Science Mission Directorate.

Video: “A Journey to Alpha Centauri” – SETI institute seminar by Christian Marois

Dr. Christian Marois of the University of Victoria gave a talk about the observation of an earth-sized planet orbiting Proxima Centauri, the nearest known star to earth: A Journey to Alpha Centauri | SETI Institute

The Alpha Centauri star system is ideal to search for habitable planets by various observing techniques due to its proximity and wide range of stellar masses. Following the recent discovery of an Earth-size planet candidate located inside the Proxima Centauri habitable zone, Dr. Marois will discuss this remarkable discovery and the planet’s potential to find life. He will also present our current instrument project for the Gemini South observatory, TIKI, to discover similar planets around the two Sun-like pair located 15,000 AU from Proxima Centauri. The Alpha Centauri system is the prime target of the Breakthrough Starshot program, a project to send small quarter-size probes to take resolve images of these new worlds, and to prepare for Humanity’s first step into a new star system.

More about Dr. Marois:

Dr Marois completed his Ph.D. at the Université de Montréal in 2004. The main topic of his thesis work was to understand the limits in exoplanet imaging and to design innovating observing strategies. After his thesis, he did postdoctoral researches at the Lawrence Livermore National Laboratory, Univ. of California Berkeley and NRC. In 2008, while at NRC, he led the team that took the first image of another planetary system (HR 8799) using the Keck and Gemini telescopes. He is currently pursuing his research at the NRC Herzberg where he is part of the Gemini Planet Imager campaign, and leading the development of instruments for imaging Earth-like planets at Gemini South and at the TMT.

TRAPPIST-1 artwork and infographics

TRAPPIST.one  is an independent site dedicated to the  TRAPPIST-1 star system, recently discovered to have seven earth sized planets circling it, three of which are in the habitable zone (see postings here and here). The site includes a page of posters and infographics about the system created by Amanda J. Smith. Here is a sampling:

Video of Panel discussion of exoplanets around TRAPPIST-1 + Travel poster

Here is a video of the NASA panel discussion of the findings by an international team of the TRAPPIST-1 star system with 7 earth sized exoplanets (see earlier posting here).

The briefing participants included:

  • Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington
  • Michael Gillon, astronomer at the University of Liege in Belgium
  • Sean Carey, manager of NASA’s Spitzer Science Center at Caltech/IPAC, Pasadena, California
  • Nikole Lewis, astronomer at the Space Telescope Science Institute in Baltimore
  • Sara Seager, professor of planetary science and physics at Massachusetts Institute of Technology, Cambridge

Here is NASA’s announcement of the discovery: NASA Telescope Reveals Record-Breaking Exoplanet Discovery
