Is this 20 questions, too?

Is he between Greenwich and 180^o longitude?

no, it was a question. I know not the answer.

Is he above 30 degrees lattitude?

Until Dave's return...

Without the use of Google, or other search engine,....

What are the Bourbon Stars?

Ok, 20 questions...

Do they have anything to do with the Sun?

Hmm... sounds like they were named after a ruler like jovian moons originally. In 18th or 19th century maybe? I guess they are moons or asteroids in our solar system, but can't come up with their names...

You are very close. Think about the discoveries of the 17th century.

Hey! what about my question?

17th century?
Must be Saturn's bright moons. Hmmm... Titan, Rhea, Iapetus, Dione and Enceladus?


EDIT: Oops, I didn't realize it's 20 questions. I'll rephrase:

Are they Saturn's brightest moons?
Are they Titan, Rhea, Iapetus, Dione and Enceladus?

Nope, not Saturn's moons. [With your great start, I doubt we will need 20]questions.

[History note: It seems that Galileo did suspect the parabolic lobes on either side of the circle of Saturn to be moons. Thus, he was able to accurately predict years in advance as their coming and going. Others thought it might be the perihelion/aphelion effects.]

Oops , I almost missed this post, too.

Yes! It had much to do with the Sun.

Parabolic lobes?It?

Are they part of the sun?

My spin on it.

It was likely in August of 1616 that Galileo wrote his good friend Cesi, "...Saturn, whose two companions are no loner two small perfectly round globes as they were before, but are at present much larger bodies and no longer round in shape,..., two half-ellipses with dark traingles in the middle and contiguous in the middle globe of Saturn, which is seen as it always has been, perfectly round."

[Added: It is believed it was at this time that Galileo came to realize that these contiguous objects were not spherical bodies. Source: Galileo at Work... Stillman Drake]

The answer, it. [Added: Not to be taken as necessarily singular in nature.]

Yes, but the Bourbon Stars were not. [So, yes and no]

Interesting that bit about Galileo and Saturn's rings.


Bourbon is one of France's royal families. So one more question about the Bourbon stars:

Were they named by a frenchman?

EDIT:
I think I finally got it. All the clues are right here in this page.

The Bourbon stars were misidentified SUNSPOTS!

IIRC there was this french guy who learned about sunspots from Galileo. Later he claimed to have found new planets (?) which in reality were sunspots. He named those imaginary planets Bourbon stars to please his king. But I can't remember his name...
I'd be very interested to learn the whole story about this affair. Any books or links on subject?

Assuming my previous answer is correct, I guess it's my turn to ask a question. I haven't read the thread but here goes:



How many known human-made objects are on a trajectory out of our Solar System and what are they?

This could be trickier than it first appears.

Oh, and urban legends about high-speed by-products of nuclear detonations doesn't count here, nor yo-yo's.

I was just wondering why you didn't call them elliptical lobes. Probably correct on both counts.

Jean Tarde was the astronomer. Note, this is a dangerous google--"Bourbon" appears to be a popular porn name, and they star in a lot of movies.

Heh, I just had to try to google "Bourbon stars", the results were just as unexpected as you said.

Thanks for the link, alas I'm not a subscriber. But googling "Jean Tarde" gave this article about the sunspot controversy: http://adsabs.harvard.edu/abs/1987JHA....18...44B

Yep! His view was in line with Scheiner's. It was Galileo who was first to correctly place them on the Sun and assume they moved due to the Sun's rotation. [I just realized that this was the first claim for an object in space to be seen to rotate. Since Galileo held that the Earth rotated, it made it that much easier to contemplate, I suppose.]

I wonder if he was rewarded for that? It worked for Galileo (the Medician moons of Jupiter), and it worked for W. Herschell (the planet George [it sure beats Uranus!] )

I should have, but I always picture a full ellipse when I use the term, which is not what is seen.

I guess you could follow Galileo and say half-elliptical!

As an aside, what is the reference to yo-yos?
