I think for many it can be interesting :wink:

Recently, I saw an interesting article on arxiv.org. It is assumed that if Proxima Centauri b. If the organisms inhabiting Proxima b, chose this way of dealing with ultraviolet light, they can be seen from Earth :smile:

I made another Proxima b based on Cham's Proxima b[DOT]
Code:

Code: Select all

"Proxima Cen b" "Proxima"
{
   Texture "venus.jpg"
   Mass 1.3  # M.sin(i) = ?? earths
   Radius 8000

    EllipticalOrbit
    {
      Period         0.04 # Fictional
      SemiMajorAxis   0.04 # Fictional
      MeanLongitude   0    # Fictional and I don't know, what does it mean
      Inclination   0 # Fictional
    }

    UniformRotation
    {
      Period      24 # hours
      Inclination   0 # Fictional
      AscendingNode  0 # Fictional and I don't know, what does it mean
      MeridianAngle   0 # Fictional and I don't know, what does it mean
    }
}

Thanks for pointing out the article on bio luminescence. It is an interesting concept.

I'm not sure how to resolve placing the newly discovered Proxima Centauri b with the planets generated in the Star Trek Proxima addon...

Speaking of which, has the .zip file to the exoplanet already been uploaded to the Celestial Motherlode?

If you're talking to me, then no. Plus nothing I upload will appear on the Motherlode.

Well, truth be told, I was addressing anybody who was working on Proxima Centauri b....

I'm the same situation as MrSpace43, nothing I upload will appear on the Motherlode for some reason... Also the Motherlode is dead btw.

Don't worry, the planets generated in the Star Trek Proxima addon will not make a mess on your Proxima Centauri b.

They wont appear because motherlode addons require approval, so they needed to be reviewed by the admins so they could decide whether or not to post it, and since no one there is active, they will never be decided on unless an admin comes back and revives it :/

Yes, I've tried submitting addons, but when mine was declined, it took around three weeks before I got an email on why.

Back to current topic, when I tried adding a planet around Proxima Centauri, the planet was completely dark, even if I set an albedo in the .ssc file.

No one can help you with this little information. Please make your SSC available, either as a [code][/code] block or an attachment. A screenshot would also be helpful. (A guess - do you have "Cloud Shadows" turned on? This sometimes causes problems.)

Edit: Also say what version of Celestia you're using.

Oh yes, I forgot to send a picture and the .ssc code. But I'm busy right now, so I'll send it later.

Relevantly, the 1970s television show Star Maidens tells of a feminist utopia planet named Medusa that was captured by the Earth's Sun, after an interstellar comet knocked it out of orbit around Proxima Centauri. Perhaps that would be a good name for the real Proxima Centauri b?

Added after 4 minutes 14 seconds:
Anyway, in case you haven't heard, there's now evidence for a second planet orbiting Proxima Centauri:

For some abnormal reason I want this new planet to be named after the TV network Jetix, even though I've never even watched it before...
