Mars, whose diameter is 47% smaller than Earth's, comes closest to that first criteria (I made the same first guess that you did). Mercury's diameter is actually 62% smaller than Earth's diameter (so it's about 38% (about 40%) of the Earth diameter)
So I got it right because I misread it :-) ... go ahead Eroica ... ask a question ... I may throw in a "women in astronomy" later if I can devise one.

Thanks, hheb09'1, I'll have to email her about that, too. So, are you all saying NASA is wrong about the 15 billion? I also see that it was discussed on the BA's blog

That’s why I got a chill, why the hair on the nape of my neck stirred. Look at that picture again, and wonder that the light recorded in it had traveled for 13.5 billion years, 98.5% of the age of the Universe itself, across that vast and terrible gulf of space.

I did some searches, and see other places that say 15 billion. I'm confused now. Help, who's right?

Eroica, it's your turn....

OK, since you insist.

What is the official name of the Lunar crater formerly known as Schlümberger?

That is a lovely riddle, and if I solved it, it is almost a shame that you can beat this kind of question to death so quickly with a few min of Googling...

So i venture that it is crater Lansberg D. This website gave me that answer - until your question I never knew that "unofficial" names even existed! I love the Internet.

I suppose the crater was named after either Conrad or Marcel Schlümberger, Alsatian-born geophysicists who happened to found what is today the worlds largest name in fossil fuel exploration.

I have some fond memories of the name - A (not very well noted) player in unremakable Hertha BSC Berlin football club went by that name (without the umlaut), I think it was in the early eighties. And in Alsace, there is the famous (and also large) Domaine Schlumberger producing fine Alsatian wines. If you happen to find one, try it. The namesakes of the crater probably hail from that familiy.

Correct on all counts. That's the site I used for this question. (I also used it last year for another question about Facula Caes. Guess I'll have to find some ungoogleable source for my next question!)

That's my goal for the questions in the Annual Quiz, but it's getting harder and harder. Usually by this time of the year, I've collected four or five questions by now. This year, nada.

Absolutely!

A question to all the participants - Since using this board I have become accustomed to the requirement that you have to provide evidence to back up your claim. That prompts me to link to the sites I get my answers from.

If doing so spoils someone's sources for questions, this is of course regrettable (Melusine obviously regretted having her source exposed after the multi-question question ).

So do the others think we should keep our sources secret for the purpose of the quiz and only expose them if differences have to be resolved?

Stay tuned for the next quiz question. We'll be back after the break...

I'd vote for OSQ (open source quizzing)

At the time of the question, it should be specified what not to specify.

Another stipulation, at the time of each question, could be whether or not googling is allowed for the entire question, or simply non-googling for a specified period. This makes guessing more fun and tolerable.

Yes, I'd say sources need not be revealed unless there is debate about the question. The only reason I've ever posted a link to my source is because I was too lazy to type out the answer. If one answers the question correctly that's all that matters; the Questioner determines whether the answer is acceptable or not.

Again, people have always used sources for hard questions, and I think that's fine, though it's honest to admit it and give yourself a pat on the back when you don't use a source. Open-book vs. revealing source are two different issues.

Yeah, revealing the Questioner's source is not kosher. I try to find questions that will be hard enough for the astro-experts, which is more difficult for me since I can't judge the difficulty very well. Thanks for acknowledging that, Arneb.

Edit add: Hheb09'1, I thought of your annual quiz when I was checking out those quizzes. I do have another source you might be able to use, but I'll PM it to you. Don't worry, I have NO chance in your quiz!

Well,yeah, sorry for the delay. I sure got the timeframe wrong with that one - intensive care eats time and energy like a black hole.

Another pic, this time not from me, although I witnessed the event in the media. Who is this guy in white, and what's special about him? Please tell a bit of the story.

Hmmmm... could the BA's blog be a clue?

Tonite is "Yuri's Nite" (Gagarin). 45 years ago he went up yonder and was the first.

No, that's not him. Gagarin did look different, didn't he?

O.K., a hint after two days of silence.

The photo does not show Yuri Gagarin. Still it is soeone who achieved a "first" in spaceflight.

I was born in 1968, and I remember the event and the media coverage.

I first thought it might Alexei Leonov, who made the first spacewalk. But surely he has too much hair? All the pictures I've found of Leonov show him as a balding individual.

It's Sigmund Jähn. The first German Astronaut. He flew in Soyuz 31 in 1978.
