    History

    Radio interferometry started in Cambridge in the mid-1940s, with funding provided by Mullard Limited and the Science Research Council. Mullard Radio Astronomy Observatory, which is located at Lord’s Bridge, Cambridgeshire, was founded by Sir Martin Ryle, an English radio astronomer, and was opened by Sir Edward Victor Appleton, an English physicist, in 1957. Altogether, the entire site comprises several large aperture synthesis radio telescopes; some of these include the ‘one-mile telescope’, the ‘5km Ryle Telescope’ and the ‘Arcminute Microkelvin Imager’.

    The site this report is based on; an active telescope, is known as the AMI Large Array (the antennas of the Archminute Microkelvin Imager Large Array). This section of the facility is made up of ‘eight 12.8 metre diameter, equatorially mounted parabolic antennas’ (whatever that means) which were formerly part of the Ryle Telescope. Each of the antennas are separated by distances which range between 18 and 110m. This particular piece of equipment, including all of the antennas, was built by the Cavendish Astrophysics Group. It was designed to study galaxy clusters ‘by observing secondary anisotropies in the cosmic microwave background arising from the Sunyaev-Zel’dovich (SZ) effect’… which obviously makes perfect sense to us laypeople. In other words, then, the AMI array is used to observe radiation, particularly that with frequencies between 12 and 18 GHz. The telescopes can, therefore, be used to determine the masses and temperatures of certain known galaxy clusters. We could go on, seeking more answers about the universe, electrons, kinematic effects, cosmic microwave background radiation and inverse Compton scattering, but my knowledge acquired from the internet is dwindling fast…

    Our Version of Events

    Now for something a little more understandable. It was raining heavily as we approached Cambridge, so heavy in fact the rain was bouncing off the road as if it were hailstone. This didn’t stop us from noticing, and quickly admiring, those tidy thatched roofed houses you folk have down below our northern borders mind. We realised, of course, that we can only dream of such things as we rolled through the various quaint villages of Cambridgeshire in our small sort-of-orange-coloured three door wader-smelling Toyota.

    After driving past it twice – quite clearly the low lying cloud must have obscured our visibility – we eventually spotted the Mullard Observatory from the roadside. Wasting no more time we peddled our beasty little orange machine into a grassy verge as fast as we could. It was too slight and slender to sink in the mud, and bold enough for other drivers to notice, so we concluded we were fine to park there. From the road, though, we faced our biggest challenge of the day: a gruelling field crossing. Normally us Northerners are used to a bit of farmland, but we found these flat Southern plains incredibly flat and wet. Our trainers squelched loudly as we plodded through mud and rather large puddles which are conspicuously missing in all our photographs. “This wouldn’t happen in our fields” we grumbled to one another. All in all it was a miserable experience.

    Eventually we reached the other side of the very flat field. We’d battled the elements and had paid the price. We were soaking. With nothing left to lose we made our way up to the fence line of the observatory and, ignoring the CCTV signs and other terrifying deterrents, found a way into the site to seek shelter beneath the giant dishes. At that point in time I was less impressed that these structures can detect cosmic radiation, I was simply thankful they’re shaped a little like giant umbrellas. We tried our best to grab a few decent shots, but decided to leave again after ten minutes due to the weather. Originally we had intended to have a wee climb up a couple of the antennas. At the time, however, our decision was unanimous: “fuck that shit”. There was none of our usual fannying around on our return to the car; for once we arrived somewhere earlier than we’d anticipated. And that, then, concludes our twenty minute stop off in Cambridge: it’s wet, muddy, flat, has nice thatched rooves and a sweet observatory.

    Explored with Ford Mayhem, Box and Husky.

    Fantastically crisp set of pictures there sir! Actually the overcast/cloudy weather compliments the subject here...

    Cheers mate. It was a challenge trying not to get raindrops on the camera lens.

    The best fields are up north, you're right with that one. Good write up as always and a cracking set of pics to go with it :thumb

    Thanks :thumb Yeah, I kind of felt that way after spending 5 minutes there. A bit of a climb up them would have been good; maybe another time.

    Great stuff. I was here at 3am on my own. The noise they make when they move is creepy. I could hear wind but couldn't feel it. Took a while to work out what it was.

    I was here earlier this year, the noise those dishes make is very creepy and if you watch really carefully you can see them align ever so slightly. Did you go inside the dishes through the hatches underneath using the ladders at the side if the cabins? I thought about it, but was put off by the fact it is still a live site. Last thing I wanted was was the university security showing up and me stuck inside having a jolly, lol. Not like there are any hiding places for miles around either now are there. ;)

    They weren't moving when we were there, everything was completely still I think. It was raining so hard we couldn't really hear any other noises. Yeah, we had a poke around, but it was difficult to get any decent photos as the rain kept getting on the lens :( Very cool site though!

    Yeah, we were there on a very clear, sunny day and even then after watching them for absolutely ages we realised them moving very, very slowly. Its barely noticable. It was probably a lot harder to notice with the rain coming down as hard as that.

    Ah, shame I didn't manage to hear them. Makes me want to return to have a listen lol :p

    Yeah, I thought that they were a load of disused satelites, it was spooky to hear them move like that. I kept thinking that the cabins were manned as a result of them moving. The fact that they detect cosmic radiation was another reason to hold off climbing into the dishes. I didn't feel like turning into the hulk on the way back to the car. I also noticed that some of the dishes are easier to climb into than others; given the location of the hatch area.

    Lmao, I would have no problem turning into the Hulk as a result of cosmic radiation. We did suddenly think that the little cabins could be manned. By then it was too late, we were pretty close to them. No one inside thankfully :thumb Yeah, I think some are easier to climb than others; I think a few of them do slightly different jobs.
