Confirmed Habitable Exomoons


The announcement included moons? I didn't see that anywhere in the press release. Do they discuss it in the briefing?

Very well presented conference on this new discovery ..Next major step is determining the mass(and hence density) of the planet so as to better characterize it interms of whether it is likely to be rocky type(Earth-like) or more like uranus/neptune type if I understood correctly. I would assume that atmospheric measurements will be possible by spectral analysis in the near future. How do they actually get to measure planetary mass ??

ye olde radial velocity technique that revealed most of the known exoplanets before Kepler was launched provides a measurement for the mass with an uncertainty due to the unknown angle between the line of sight and the plane of the planet's orbit. In the case of transiting exoplanets you know that the angle is practically zero, so the technique directly gives the value of the mass.

I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

Thank you! I'd been monitoring space-multimedia.nl.eu.org and youtube.com/user/NASAtelevision waiting for this to pop up, and was disappointed that it hadn't appeared.

For anyone who is scanning this thread looking for a Youtube clip, here it is:

Awesome that they end with a quote from Rui. Kepler's success is so inspiring, I really hope this is a driver for getting the next generation of telescopes; Kepler-like spacecraft that can map multiple fields of view as well as the Terrestrial Planet finder chronograph and interferometer. WFIRST is set for launch in 2022, but I think it's the only new planet hunter in the works. /sigh

For those in the CA Bay Area:

SETI Institute in Sunnyvale
Wednesday, December 7, 2011 - 7:00pm
The Search for Habitable Exoplanets in the Kepler Era and Beyond
Sara Seager
Planetary Science and Physics, MIT

For centuries people have wondered, “Are we alone?” With hundreds of planets now known to orbit other stars, we are finally able to begin answering the ancient questions, "Do other Earths exist? Are they common? Do any have signs of life? NASA's Kepler space telescope will soon tell us the statistical numbers of Earth-size planets orbiting sun-size stars. Beyond Kepler is the search for potentially habitable worlds around nearby, sun-like stars. Professor Seager will discuss how astrobiology and space engineering research will come together to enable us to discover and identify other Earth-like worlds.
---------------------

If you've got any questions let me know and I'll try to ask.

Just FYI...Kepler has NOT found any exomoons let alone habitable exomoons, despite what that website that Mongo posted says. Geoff Marcy said that unequivocally yesterday at his Sagan Lecture at AGU.

I dug into the site, and it appears that when they are talking about exomoons, they mean gas giants that are sufficiently large to plausibly host orbiting Earth-like moons.

The Mass and Radius of Potential Exomoons

Latest List of Potential Habitable Exoplanets and Exomoons

They are using the same planet to moon-system ratios seen in our solar system for the gas and ice giants (Jupiter, Saturn and Neptune all at about 3000:1, Uranus at about 10000:1)

They then use this ratio to estimate the mass of the largest plausible moons of gas giants that are already known to be in the star's habitable zone.

So yes, the exomoon numbers are speculation based on solar system statistics. They do state on the home page that no exomoons have been observed yet, but they could be more clear that the listed exomoon statistics are conjectural.

Is there a schematic view of this new Kepler-20 system? Sounds like it's Neptune, Mars, Neptune, Earth, Neptune. Within the orbit of Mercury. Crazy.

[edit] There are at least videos in the presskit:
