The Combined Array for Research in Millimeter-wave Astronomy (CARMA) was an astronomical instrument comprising 23 radio telescopes. These telescopes formed an astronomical interferometer where all the signals are combined in a purpose-built computer (a correlator) to produce high-resolution astronomical images. The telescopes ceased operation in April 2015 and were relocated to the Owens Valley Radio Observatory for storage.
2nd visit and now with the benefit of the WA converted Sigma. This dish is one end of the of the 'One Mile Array'. This telescope array was the first long-baseline Earth-rotation aperture synthesis interferometer. It is now mothballed.
Tintagel Castle (Cornish: Kastel Dintagel) is a medieval fortification located on the peninsula of Tintagel Island, adjacent to the village of Tintagel in Cornwall, England, in the United Kingdom. The site was possibly occupied in the Romano-British period, due to an array of artefacts dating to this period which have been found on the peninsula, but as yet no Roman era structure has been proved to have existed there. It subsequently saw settlement during the Early Medieval period, when it was probably one of the seasonal residences of the regional king of Dumnonia. In the 13th century, during the Later Medieval period, after Cornwall had been subsumed into the kingdom of England, a castle was built on the site by Richard, Earl of Cornwall, which later fell into disrepair and ruin. Archaeological investigation into the site began in the 19th century as it became a tourist attraction, with visitors coming to see the ruins of Richard's castle, excavations in the 1930s however revealed significant traces of a much earlier high status settlement that had trading links with the Mediterranean during the Late Roman period.[1]
Not incidentally, the castle has a long association with the Arthurian legends, going back to the 12th century when Geoffrey of Monmouth in his mythical account of British history, the Historia Regum Britanniae described Tintagel as the place of Arthur's conception. According to the tale told by Geoffrey, his father, King Uther Pendragon, was disguised by Merlin's sorcery to look like Gorlois, Duke of Cornwall the husband of Ygerna, Arthur's mother. [2]
Today, Tintagel Castle is a tourist destination, as it has been since the mid-19th century, and it is managed by the governmental organisation English Heritage.
