astroENGINE.com hosts the 51st Carnival of Space, a lengthy compilation indeed, from which I’ll draw Ian Musgrave’s interesting post on a possible transit at 83 Leonis as the feature of the week. If you want to find out what it’s like to get your hands dirty juggling the data, trying to sift out signal from noise and working with all the imponderables that go into spotting the signature of a transiting world, have a look. Ian finds a noisy 83 Leonis but one that just might show a transit. A self-described ‘mathematically challenged biologist,’ this is a writer whose work is always worth watching. In this case, what he’s doing reflects the broadening participation of amateurs in exoplanet projects, an idea Greg Laughlin has championed, so it’s no surprise to see that Ian has drawn from Laughlin’s expertise in his current work.
In Centauri Dreams, Paul Gilster looks at peer-reviewed research on deep space exploration, with an eye toward interstellar possibilities. For many years this site coordinated its efforts with the Tau Zero Foundation. It now serves as an independent forum for deep space news and ideas. In the logo above, the leftmost star is Alpha Centauri, a triple system closer than any other star, and a primary target for early interstellar probes. To its right is Beta Centauri (not a part of the Alpha Centauri system), with Beta, Gamma, Delta and Epsilon Crucis, stars in the Southern Cross, visible at the far right (image courtesy of Marco Lorenzi).

If you'd like to submit a comment for possible publication on Centauri Dreams, I will be glad to consider it. The primary criterion is that comments contribute meaningfully to the debate. Among other criteria for selection: Comments must be on topic, directly related to the post in question, must use appropriate language, and must not be abusive to others. Civility counts. In addition, a valid email address is required for a comment to be considered. Centauri Dreams is emphatically not a soapbox for political or religious views submitted by individuals or organizations. A long form of the policy can be viewed on the Administrative page. The short form is this: If your comment is not on topic and respectful to others, I'm probably not going to run it.
