Kepler Investigator Says 'Galaxy Is Rich In Earth-Like Planets'
astroengine writes "In a recent presentation, Kepler co-investigator Dimitar Sasselov unexpectedly announced news that the Kepler Space Telescope has discovered scores of candidate Earth-like exoplanets. Not waiting for the official NASA press release to announce the discovery, Sasselov went into some detail at the TEDGlobal talk in Oxford, UK earlier this month. This surprise announcement comes hot on the heels of controversy that erupted last month when the Kepler team said they were withholding data on 400 exoplanet candidates until February 2011. In light of this, Sasselov's unofficial announcement has already caused a stir. Keith Cowing, of NASAWatch.com, has commented on this surprise turn of events, saying it is really annoying 'that the Kepler folks were complaining about releasing information since they wanted more time to analyze it before making any announcements. And then the project's Co-I goes off and spills the beans before an exclusive audience — offshore. We only find out about it when the video gets quietly posted weeks later.' Although Sasselov could have handled the announcement better (and waited until NASA made the official announcement), this has the potential to be one of the biggest astronomical discoveries of our time — so long as these Earth-like 'candidates' are confirmed by further study."
Seems like the only info released was a distribution of planet size. Without planet composition, I would describe these as Earth-size, not Earth-like. It's a little early to get excited.
There are more things in heaven and earth than are dreamt of in your philosophy.
I agree. Water presence? Temperature within habitable range? At least a primordial atmosphere? Not sure if Kepler is the right tool to collect that kind of data, but to call them "earth like" seems premature. Granted, if the size approaches that of earth chances are they're rocky, solid planets, but that's it.
It's really sad that a discussion about the possible detection of Earth-sized planets around other stars is dressed up in "it's our data and we want to publish first" and stuff like that.
Humanity will, one day, pay dearly the fact that scientists are forced to fight for resources...
Anyway, this is interesting news. If computers were considered "the revenge of the nerds", I'm curious what the next few years will be called.

The Star Trek classification system would indeed be far better than the whole "What's a planet" argument definitions we've had (which has been hard enough with just our solar system), and things like Dwarf planets etc. We have classes for stars, so why not planets...
