Prevalence of Earth-size planets orbiting Sun-like stars, Proceedings of the National Academy of Sciences (full article behind paywall)
"We find that 22% of Sun-like stars harbor Earth-size planets orbiting in their habitable zones. The nearest such planet may be within 12 light-years."
"The research was funded by UC Berkeley and the National Science Foundation, with the assistance of the Keck Observatories and NASA."
NASA paywalls first papers arising from Curiosity rover, I am setting them free, Michael Eisen, UC Berkeley
"This whole situation is even more absurd, because US copyright law explicitly says that all works of the federal government - of which these surely must be included - are not subject to copyright. So, in the interests of helping NASA and Science Magazine comply with US law, I am making copies of these papers freely available here"
Keith's 5 Nov update: PNAS has finally made this paper available to the public free of charge. Its just baffling how NASA is unable to coordinate this sort of thing in advance rather than after the fact. Now, will NASA make a point of letting people know that this paper is online?
Keith's 4 Nov note: This stunning, groundbreaking research was funded by NSF and NASA (via tax dollars), announced at a NASA press conference regarding data from a NASA spacecraft (paid for with tax dollars) and ... that's right - you have to pay money to read the article. (2 days for $10.00, 7 days for $25.00.) An index page says it is "open access" but that is not how it is set up - check the image of the login/pay box you get on the right. And NASA won't post it either (they never do). Oh yes, the journal that is charging you for access is published by the National Academy of Sciences which itself is almost totally dependent on government grants (recycled tax dollars).
I applaud UC Berkeley's Michael Eisen for his earlier stance on freely circulating publications from NASA Mars research and hope that he'll convince his fellow UC Berkeley faculty member (Geoff Marcy) to do the same. Hey wait: .... didn't Geoff Marcy get all upset about lack of openness, access, exchange of data and all that when NASA banned Chinese scientists from attending and participating in this very same conference?
"Geoff Marcy, an astronomy professor at the University of California at Berkeley, told the Guardian: "It is completely unethical for the United States of America to exclude certain countries from pure science research." Marcy has said he will not attend the conference."
C'mon Geoff. Set your (our) data free about all of these potentially habitable planets. We paid for the research. Its the "ethical" thing to do.
