That's probably more realistic than all the hydrogen gas hovering over one side. Your pic shows quite nicely an extended exosphere of hydrogen at or near escape. The only thing that could be improved (as much as I can tell) would be seeing the planet's shadow in the extended atmosphere, but Celestia doesn't render this of course.

Hi Tim,

Thanks, you're very kind :)

It's just my imagination of 51Pegasi/b; only an impression and - first of all - this should be an homage to Michel Mayor and Didier Queloz and their colleagues at the Observatoire de Genève for the first discovery of an exoplanet. For me a "milestone" of mankind. Similar to "our" first steps on the surface of the moon (...and other important discoveries of course).

Let me say one word out of topic:
While I was rummaging (again) in older topics here at shatters.net I found your thread "Star Trek addons by fungun" and read - after you decided "...to not release the larger, more complex addons..." -
fungun wrote:Well after the kind words in emails and PM's, I decided to stay with the ML.

You probably must have a good and solid character. Not many people swing round and change their minds after they made such a decision. :)

Already elsewhere I wrote and I may repeat myself: I am not an enthusiast in SF but I like the Star Trek series because these movies are transporting a good message of humanity. And that's not an unimportant thing :idea: :wink:

So, you're doing a great job here :D

Thanks
Michael

Yes, this is the accurate description of my problem which I have if I look at the 51Pegasi/b picture above. :wink:

Thanks for your comment, Hungry4info; I know you are well versed in "exoplanetary" things. :)

This gives me the courage to load up my 51Pegasi/b add-on on CML...
(at first I have to finish the night texture though)

Accordingly with Giordano Bruno, an heretic philosopher burned alive by the Church in Rome (1600 a.C)., there is an "infinity of worlds" (mean: planetary systems). Thus, fortunately, these men are still alive; so one could rise the issue on what is the "milestone". :wink: (tipical question in sociology of science).

Mind the propriety of an heat transported by convective motions: the backside could be more warm of the frontside...

Actually, A. Wolszczan published the first discovery of an extrasolar planet three years before Mayor and Queloz reported the existence of 51 Peg b.
A planetary system around the millisecond pulsar PSR1257+12 (1992)

Surprisingly, the planetary system around PSR B1257+12 received a lack of attention and excitement, and even now gets consistently overlooked in claims of "the lowest mass exoplanet ever!"

Oh yes, our world is a slapstick comedy sometimes. :roll:
Of course you're right; I should write: 51 Pegasi/b is the first discovered extrasolar planet orbiting a sun-like star!
Thanks, for this correction!
(Well, I'd like to underline this sentence (from above) now: You are very well versed in "exoplanetary" things. :)

Thanks again

Never mind. Of course the "milestone" is for you (and me) their findings in exoplanet. Nonetheless is also a "milestone" the fact that they haven't been put into the fire, how was in the past, when such concerns were yet only theorized. :wink:

"milestone"
Normally i think of a Roman mile marker stone
or
X % of a project done by X date as stated in a contract .
OpenSUSE 12.2 x86_64 & ScientificLinux 6.4 x86_64

Oops, a language problem (on my side);
I would say: A big step for mankind. (Like Armstrong's "giant leap...")

...and concerning to Giordano Bruno - as much as I know - it wasn't the church, but the governor of Rome... (Church had asked for leniency.)

This "meaning issue" is beautiful, because John is actually in true for what concern the "Roman" meaning; while for the "contract" I should say, in my land, "a step" :wink: Nonetheless, is interesting that in Germany and in Italy we ascribe the same meaning to "milestone". Maybe because for the Romans the last milestone the last part of the explored land, and so on?

The governor of Rome was the Pope... :wink: Next year will be the 150 years anniversary that the Pope is no longer the governor of Rome (Unity of Italy).

Yes. Because the Romans brought the civilization to Germany. And this was a great social progress - a "milestone" - for the further future of Germany.( But I'm not sure if Germany has understood everything correctly )

...and where do 51 Pegasi/b comes in here...? Well, I don't know :wink:

I have finished the night texture and added a second cloud-layer (for a better heat-simulation).
Into the hires folder I put a more detailed map with the same size (4k) but somewhat structured. Here's the result...
