Really? That's not what I'm thinking about.

I am not a microbiologist, only a physician. I indeeed used M13 bacteriophage for site-directed mutagenesis experiments during my M.D. thesis work (12 years ago).

The manual for the mutagenesis kit had a photo of the M13 globular on its front page. That was how I got the idea. Here and here are micrographs of the phage.

ATM, you always seem to be the one who finds the little flaws in my questions. #-o - I have been doing amateur astronomy for a bit of time now, and I never came across the name "Great Hercules cluster" - It was always just M13. Maybe I shouldn't have put too much emphasis on language use here, as I am not a native speaker of English. Sorry if I put you off the right track with this one. ops:

We'll file that under C, for "Coincidence"! Interesting one, though.

Eroica, your questions are too tough - After such a long silence, I'll try a new question:

There was once a theory that there was another planet inside the orbit of Mercury - What was its provisional name?

Even to Google!

Diphda and Fomalhaut

Deneb Kaitos (Beta Ceti) The brightest star in Cetus ...Its Arabic name means the “whale’s tail,” while an alternative name “Diphda” (or “Dipda”), also Arabic, refers to the “first frog,” where Formalhaut was the “second frog.”

Here's an interesting question: Why did they think there was another planet, Vulcan?

The small difference between the predicted and observed orbit of Mercury was attributed to Vulcan. The real problem was that Newton's Laws are only approximate, when you are as close to a massive body (the Sun) as Mercury is, the difference, though very small, is nonetheless measurable. When you use GR instead of classical mechanics, the predicted orbit matches the observed orbit.

There was also sunspots report that encouraged it's existance, but this is only supplemental.

Right, which pretty much makes Vulcan Einstein's baby.

But I think it's Fram's turn to ask a question.

Asimov had an interesting essay on Einstein's relationship to Vulcan.

I just plucked this gem from the article -

And isn't that what Bad Astronomy and JayUtah's Clavius are about?

Sorry, I answered and was gone then...

What is the colour of the Sun?

What is the name of the oldest artificial satellite in orbit around the Earth that is still working? Year of launch is appreciated as well...

Oldest still in orbit, non-operational: Vanguard 1 (1958)
Oldest operational in any orbit: Pioneer 6 (heliocentric, launched Dec. 16, 1965); I was not able to see any contacts after 2000, but that one was clearly successful)
Oldest operational in Earth orbit seems to be AO-7 , launched in 1974
There is an older one, ATS-3, but I couldn't confirm ontacts after 2000. Launch was in 1967.

Allright, there you go! Some amazing feats of technology there...

A list of active and possibly active old satellites in earth orbit. Strangely, Oscar 7 is missing here (though it was definitely working in 2004, 30 years after its launch).
