LOFAR, the World's Biggest Telescope, Is Up and Running 100

Posted by timothy from the can-we-call-this-a-meta-telescope? dept.
HansonMB writes with this bit from Motherboard: "Back in September, Motherboard ventured into the English countryside to listen to the universe. There lives a brand new piece of Europe's already-massive Low Frequency Radio Array radio telescope: a clever EU-wide installation that uses low-tech antennas and supercomputer-power data processing to transform into a giant mega-telescope, absorbing cosmic radio waves from the full sky." That was then; now, says the article, "In the past month, using signals from the new station, LOFAR has delivered its first EU-UK radio 'pictures.'"

              It completely depends on context.

              If I'm in Britain, and I say to someone I'm thinking of taking a holiday in Europe then it means I'm not going to the UK or Ireland (since I'd say I was going to e.g. Wales). I'm going to multiple countries, otherwise I'd just name the country.

              If I say "Europe is going to have do X because China's doing Y" that includes the UK and Ireland. It might mean just the EU (or EEA, EC, ...), rather than the continent.

              If I'm speaking to someone who isn't European, or if I'm not in Europe, then the UK is included when I say "Europe".

              Some British people don't like the EU. It's usually obvious whether they include the UK when they say "Europe", and will depend on whether they're comparing football to baseball, or regurgitating what they read in the Daily Mail.

              (FWIW, I've been "to America" four times. Two of those trips included Canada as well as the USA, but I don't usually mention that unless questioned further. Canadians might not like that.)

What's more LOFAR electronics are designed to supress radiation in the FM frequencies because they are so enourmous compared to the astronomical signals we're looking for.

There is one substation in the UK, most are in the Netherlands (since the center is there), some are in Germany, one in France and one in Sweden. These substations are assembled in a giant phased array by means of a supercomputer. This array can look at multiple parts of the sky at the same time while having a great resolution in low frequencies.
