Stargazing Final Results

The response from BBC Stargazing viewership  has been amazing! We have over 100,000 unique vistors to the Planet Hunters website since the start of the first broadcast on Monday. With volunteers participating in the UK  and around the world (see where our classifications came from), we’ve completely shattered our goal of 250,000 classifications during BBC Stargazing, crossing 1 million classifications before the last broadcast even started! Well done and thank you- it would take a single person more than 2.5 years of non-stop work to match your collective effort!

 With all the clicks, the science team -and their computers – have been working hard to keep up! We’ve been searching for planet candidates identified in the classifications to present for the final night of Stargazing. We have several interesting candidates that we’ve identified in the new Quarter 4 data. We still need to do careful vetting to confirm we can reject other false positives that mimic transit signals as the source for the transit-like events. But with these detections, we think we’re on the right track.  One in particular looks promising and we’ve identified transits in multiple Quarters of Kepler data, with transits appearing every ~90 days. Two transits were spotted in Quarter 4 observations by Lee Threapleton and Chris Holmes, where it was noticed by the team as the Planet Hunters community was discussing the light curve on Planet Hunters Talk. The wonderful denziens of Talk, particularly Kian Jek, had already done much of the preliminary analysis. This roughly Neptune-sized (~3.6 Earth radii)  planet candidate orbiting around SPH43066540 was presented by Chris live on air during the broadcast.  There’s more work to be done to confirm whether these candidates are true planets – in particular, we need to talk to our friends on the Kepler team – but we’re on our way. Congratulations to you all – all that hard work is paying off. 

Although we’ve hit the million classification mark for BBC Stargazing, there is more work to be done and new data to search and planets to find. We’re uploading the next three month’s worth of Kepler observations to the site in the near future. We can’t wait to find out what’s awaiting us.

    Hello,

    It is my understanding that planets are not named, so the unofficial name given to the new planet by the BBC Stargazing team was nothing more than good television.

    From a personal point of view it is exciting to be part of this process but obviously the real credit for the discovery belongs to the scientists involved in collecting and collating the data.

    Hi

    Sorry for the confusion, Tom – we’ll be following the normal convention for this planet candidate, including crediting those who found it on Talk or in quarter 2 as well as Lee and Chris who were the only people who had, before yesterday, marked the transits in the quarter 4 on the interface. I don’t know if you saw the program, but we tried to make clear that planets couldn’t be officially named before we had a lot of fun playing wit hthe idea of naming the planet.

    Hope that clears things up.

    Chris

    Hi, I’ve noticed that quite a number of the ‘quiet’ stars have one anomalous blip at very close to 2.5. Is this an instrument snag or is it significant?

    I think all the planets that we find are probably already named by there owners. Earth probly has hundreds of names but one always suits better than the other :) Home! :) id love to name a planet but to even find one would be amazing.

    planethunters.org is both entertaining and educational and i really like that. Still, as i understand its not meant only for scientist, so it would be good idea to have more examples and hints what different stars and planets orbiting them look a like, Also more info about current star(mass, distance, etc) you looking at would be cool. Just my 26 cents:)
