Little Eversden

Great Eversden is a village 6 miles south-west of Cambridge, England. The population of the civil parish at the 2011 Census was 241. The Prime Meridian runs through the parish just to the east of the village, separating it from Little Eversden. Great Eversden is a small village of about 85 houses. It broadly takes the shape of a cross, with the Harlton to Kingston road forming the East and West arms (called Church Street and the High Street), and the no-through-roads of Chapel Road and Wimpole Road forming the North and South arms.

Comberton Village College is an 11–18 mixed secondary school and sixth form with academy status on the edge of Comberton village in Cambridge, Cambridgeshire. It opened in 1960 as a village college.

Toft is a village situated in Cambridgeshire, England. It is approximately six miles to the west of Cambridge, and is situated within four miles of the M11 motorway. It has approximately 600 residents and 200 homes. Comberton Village College and Comberton Sixth Form fall within the Toft Parish boundary. The village has two churches, St Andrew's Parish Church and Toft Methodist Church.Just to the east of the village is Cambridge Meridian Golf Club, which has the Prime Meridian running through the 14th fairway. The name "Toft" is derived from an old Viking word meaning "curtilage" or "homestead".

Orwell Clunch Pit is a 1.8-hectare (4.4-acre) biological Site of Special Scientific Interest on the northern outskirts of Orwell in Cambridgeshire. It is owned by Orwell Parish Council and managed by the Clunch Pit Management Trust.This former stone quarry has a rich chalk grassland flora, a habitat which has become scarce in eastern England. Herbs including kidney vetch, horseshoe vetch, spiny restharrow and wild thyme.There is access from Quarry Lane.

Comberton is a village and civil parish in South Cambridgeshire, England, just east of the Prime Meridian.

Harlton is a village and civil parish in Cambridgeshire in the United Kingdom. The village is 5 miles (8.0 km) south-west of Cambridge and neighbours Haslingfield.

The Mullard Radio Astronomy Observatory (MRAO) is located near Cambridge, UK and is home to a number of the largest and most advanced aperture synthesis radio telescopes in the world, including the One-Mile Telescope, 5-km Ryle Telescope, and the Arcminute Microkelvin Imager. It was founded by the University of Cambridge and is part of the Cambridge University, Cavendish Laboratories, Astrophysics Department.

Kingston is a small village and parish in the East of England region and the county Cambridgeshire in the United Kingdom. Situated 7 miles to the west of Cambridge, the population at the time of the 2001 census was 214, increasing to 238 at the 2011 Census.The ancient parish is 1,907 acres (772 ha) in size, at an altitude of between 80 and 250 feet. The land is largely agricultural, with Kingston Wood covering around 100 acres.

The 4C Array is a cylindrical paraboloid radio telescope at the Mullard Radio Astronomy Observatory, near Cambridge, England. It is similar in design to the Molonglo Observatory Synthesis Telescope. It is 450 m long, 20 m wide, with a second, moveable element (now mostly removed; some of it is still visible, beyond COAST). The first large aperture synthesis telescope (1958), it was also the first new instrument to be built at Lord's Bridge, after the Observatory was moved there in 1957, and needed 64 km (40 mi) of reflector wire (since removed). The 4C operated at 178 MHz (1.7 m), and located nearly 5000 sources of the 4C (4th Cambridge) catalogue published in 1965 and 1966, which helped establish the evolution of the radio galaxy population of the universe. The telescope is now inoperable. It is flanked to the northwest by the Cosmic Anisotropy Telescope enclosure and to the south by the One-Mile and Half-Mile Telescopes.

The Cosmic Anisotropy Telescope (CAT) was a three-element interferometer for cosmic microwave background radiation (CMB/R) observations at 13 to 17 GHz, based at the Mullard Radio Astronomy Observatory. In 1995, it was the first instrument to measure small-scale structure in the cosmic microwave background. When the more sensitive Very Small Array came online, the CAT telescope was decommissioned in a ceremonial bonfire.

The Interplanetary Scintillation Array (also known as the IPS Array or Pulsar Array) is a radio telescope that was built in 1967 at the Mullard Radio Astronomy Observatory, in Cambridge, United Kingdom, and was operated by the Cavendish Astrophysics Group. The instrument originally covered 4 acres (16,000 m²). It was enlarged to 9 acres in 1978, and was refurbished in 1989. The array operates at a radio frequency of 81.5 MHz (3.7 m wavelength), and is made up of 4,096 dipole antennas in a phased array. Using 14 beams, it can map the northern sky in one day. The observatory's staff use sheep to keep grass away from the antennas because a lawn mower cannot fit in the spaces. Antony Hewish designed the IPS Array to measure the high-frequency fluctuations of radio sources, originally for monitoring interplanetary scintillation. Hewish received a Nobel prize after the high time-resolution of the array allowed the detection of pulsars by Jocelyn Bell in 1967.The IPS Array has more recently been used to track and help forecast interplanetary weather, and specifically to monitor the solar wind. It is now essentially retired, and has lost a significant fraction of its area.

The Half-Mile Telescope was constructed in 1968 (2 aerials) at the Mullard Radio Astronomy Observatory with two more aerials being added in 1972, using donated dishes (total cost was £70,000). Two of the dishes are fixed, while two are moveable and share the One-Mile's rail track; to obtain information from the maximum number of different baselines, 30 days of observing were required. Observing frequency 1.4 GHz (21 cm wavelength), bandwidth 4 MHz. Used for Hydrogen Line studies of nearby galaxies and produced the first good radio maps of hydrogen distribution (as a function of its velocity), for M33 and M31 (also produced nearly 20 PhDs and 50 published papers). The telescope was operated by the Radio Astronomy Group of the Cambridge University.
