Universe Puzzle No. 9

Last week’s Universe Puzzle was a wee bit too hard, wasn’t it?

Well, this week’s one should be a tad easier, though you will still need to cudgel your brains a bit and do some lateral thinking (five minutes spent googling likely won’t be enough). But, as with all Universe Puzzles, this is a puzzle on a “Universal” topic – astronomy and astronomers; space, satellites, missions, and astronauts; planets, moons, telescopes, and so on.

Which is the odd one (or two!) out?

Crawford Hill, Dover Heights, Kootwijk, Richmond Park, Seeberg Hill, Wheaton.

UPDATE: Answer has been posted below.

Seeberg Hill is where the Gotha Observatory (Seeberg Observatory, Sternwarte Gotha or Seeberg-Sternwarte) was located; it was an optical observatory. All the others are, or were, sites of radio telescopes, or observatories: Crawford Hill, in New Jersey, is where the CMB (cosmic microwave background) was first detected; Dover Heights is the site of Australia’s first radio telescope/observatory; Kootwijk is the site of the Netherlands’ first radio observatory; Richmond Park, in London, is where Hey, Parsons, and Phillips, in 1946, detected the first discrete extra-galactic astronomical source (Cygnus A); and Wheaton, in Illinois, is the site of Grote Reber’s first radio telescope.

Wheaton would also be a good answer; Grote Reber built his first radio telescope on his own (all the others are the result of efforts by institutions).

For ‘two out’, several answers are possible. For example, Seeberg Hill and Crawford Hill (the microwave region of the electromagnetic spectrum is not, necessarily, the same as the radio).

Congratulations to gopher65 and iantresman!

    They are all Radio Telescope locations, but I damned if I can see any differences.

    Dover Heights was the first in the southern hemisphere, and possibly first ever (though the American dispute that)
    Weaton was the first radio dish,
    Seeberg Hill was on top of a lighthouse,
    Crawford Hill discovered the Big Bang, though wasn’t it might have been amicrowave ‘scope
    Kootwijk was Dutch, and was first to map the Milky Way at 21cm – still remember the famous map in my head

    So Crawford Hill and Kootwik are the odd ones out as they discovered important stuff – the others were testing on the theory of radio observations.

    … oh, I am viewer No 10 (at the bottom of the screen…)

    You gotta be quick in these question here!!

  3. SteveZodiac says

    The odd one out is Kootwijk, it was a transmitter, the rest are receivers

  4. Matthew Burns says

    Kootwijk, and Wheaton, because they are one word while the others are two word names.

    Wheaton, it’s the only one named after an actor who played on Star Trek.

    Crawford Hill, Dover Heights, Kootwijk, Richmond Park, Seeberg Hill, Wheaton.

  5. SteveZodiac says

    or..
    there is an Kootwijk lasre ranging observatory in Apeldoorn, Netherlands

    Crawford Hill did CMB radio astronomy , Dover Heights did solar RA, Richmond Park did RA, and Wheaton Illinoid was where Groet Reber made the first radio dish so Seeberg Hill and Kootwijk are the odd ones out, dealing with photons

    but there is a Wheaton College optical Telescope in Norton Mass.There is even an optical observatory in Richmond Hill Ontario…..

  6. SteveZodiac says

    oops! Typos that’s LASER and ILLINOIS

  7. Navneeth says

    “CMB radio astronomy”

    The what, now?!

  8. Hon. Salacious B. Crumb says

    Kootwijk is the odd one out. It is the only one with the unpronounceable name (and the letter “J”)!

    Also the statement; “The odd one out is Kootwijk, it was a transmitter, the rest are receivers” Is not quite true. They did also had in the early days a radio telescope!

  9. Hon. Salacious B. Crumb says

    “CMB radio astronomy”?

    Do you mean Cosmic Mega Blasts radio astronomy?

    There are other choices…

    – Xtree for Windows Button Bar file
    – Chase Manhattan Corporation
    – Capital Management Branch
    – Crushed Miscellaneous Base
    – Compagnie Maritime Belge
    – Core-Mantle Boundary

    …but the clasic one I think is;

    CMB – Call Me Back

    (little green men, anyone?

    Note : Actually, it is; CMB – Cosmic Microwave Background

  10. gopher65 says

    Navneeth: CMB = Cosmic Microwave Background

    1) Wheaton and Seeberg Hill were used exclusively for civilian research, unlike the others
    2) Seeberg Hill has never had any radio telescope on that site (as far as I can see?)

  11. SteveZodiac says

    Yeah OK Microwaves are not strictly radio….

    I have never been arrested in Seeberg Hill. I was just assisting the police with their enquiries.
