Linked from

The 13 pages that link to Arecibo Observatory, each with the reason it gives.

• Radio telescopeBroader topic: Its immense collecting area enabled landmark studies of pulsars, planets, and the ionosphere.

• Radio interferometryCompared with: Its enormous single collecting surface contrasted with the distributed baselines of an interferometric array.

• Radar astronomyRelated: Its transmitter enabled decades of high-resolution radar studies of solar-system bodies.

• Binary pulsarRelated: Hulse and Taylor discovered their binary pulsar using its radio telescope.

• Parabolic reflectorBroader topic: Its spherical primary reflector required corrective optics to handle the resulting aberrations.

• Very Long Baseline ArrayCompared with: Arecibo concentrated collecting area in one dish; the VLBA gains resolution by linking distant antennas.

• Green Bank TelescopeCompared with: Arecibo collected more signal over its accessible sky but could not steer its dish like Green Bank.

• Zone of AvoidanceRelated: Arecibo surveys detected neutral-hydrogen galaxies in parts of the obscured sky.

• Five-hundred-meter Aperture Spherical TelescopeCompared with: Like FAST, Arecibo used a fixed reflector in a natural depression, but had a smaller aperture.

• Joseph Hooton Taylor Jr.Related: Hulse and Taylor found the binary pulsar using Arecibo’s radio telescope.

• PSR B1937+21Related: The discovery observations used Arecibo's sensitive radio telescope.

• Russell Alan HulseRelated: Hulse used its telescope to survey pulsars and identify PSR B1913+16.

• IC 342/Maffei GroupRelated: Radio observations helped identify and study galaxies otherwise difficult to see through the Zone of Avoidance.
