The Argus Array (full name, Argus Subspace Radio Telescope Array) was a Federation subspace telescope in service in the latter half of the 24th century. It was located at the edge of Federation space in the Alpha Quadrant. In the 2360s, this array was located three light years from Cardassian territory.

An unmanned structure, the Argus Array consisted of eighteen hexagonal subspace antennae clusters, each powered by an individual fusion reactor and all regulated from a central computer. It was capable of collecting detailed images of objects many light years away. (TNG: "The Nth Degree", "Parallels")

During one of its studies of subspace, the Argus Array suggested an upper bound on a phenomenon known as the Hofstadter effect. (TNG-R: "Redemption II" display graphic)

The Argus Array malfunctioned in 2367, following contact with a Cytherian probe, which disrupted the Array's computer systems. The problem was fixed by the USS Enterprise-D. (TNG: "The Nth Degree")

In different quantum realities, the Enterprise-D returned to the Argus Array in 2370 to investigate why it was not transmitting data. In these parallel universes visited by Lieutenant Worf, the cause of the array's shutdown was varied. In one, the Cardassians had reprogrammed the array to spy on Federation outposts; in another, it had suffered a simple mechanical failure. In one universe, the Cardassians had destroyed the array; in another, the Bajorans did so. (TNG: "Parallels")

In 2399, the location of the Argus Array in neutral space was labeled in a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters. (PIC: "Maps and Legends")

The array was named after Argus Panoptes, a giant in Greek mythology with a hundred eyes. (citation needededit)
For the remastered "Redemption II", the old graphics were replaced and the Argus Array was mentioned in the new text.
