   Oh god, I’m about to get all sciency… Mars is actually in the habitable zone, which is why we’re so invested in it.

     You may want to take a coat though, it would still be a tad chilly.

     Weren’t the Dutch thinking about sending some people there as part of a reality show? Like Big Brother, but without people getting voted off (Or ever returning)?

   hey Luke, I’m happy to say we’ve finally made use of this image in one of Andrew’s posts about exoplanets - http://blog.thingswedontknow.com/2013/05/the-search-for-another-earth.html

   Thanks again for letting us use it! 🙂

   Hi Luke.

   I’m an american astrophysicist living in France. I really like this habitable zone cartoon and would like to use it in a blog post I’m writing (planetplanet.net). However, there are a couple little mistakes.

   First, Venus’ orbital distance is 0.72 AU, which should put it in the HZ according to your values.

   Second, your HZ limits are a little off. Here are a couple of links with recent estimates: http://adsabs.harvard.edu/abs/2013ApJ…765..131K and http://adsabs.harvard.edu/abs/2007A%26A…476.1373S. These results suggest that the inner edge is close to EArth’s orbit, at 0.9ish AU, and the outer edge is probably beyond Mars’ orbit, although of course it depends on the type of planet you are dealing with.

   I known I’m insanely picky about these things! In any case, if you happen to make an updated version of the image in the next few days let me know and I will link to it from my blog.

   cheers
   Sean

     Hi Sean,
     Thanks for the input. You’re welcome to use the comic and modify it for a non-commerical blog [All my comics are licensed under the Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales license].
     As for the science, I’m going to keep this as it is, mostly out of laziness. The important message here is the schockingly under-reported Hungry Space Bear threat.
     Cheers,
     Luke

       Hi Luke — I went ahead and put the image in a recent blog post, with credit to you of course. Here is the link: http://planetplanet.net/2013/09/16/the-habitable-zone-part-1/

       cheers
