Cerro Tololo Inter-American Observatory

[4] He went to the semi-arid region of Coquimbo, South of the Atacama Desert, and climbed numerous mountains, carrying a Danjon telescope and an interferometer to determine visibility and accurately measure the wavelength of light.

[7] In 1974, construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope, but smaller facilities have been built since then.

[1] The Small and Medium Research Telescope System (SMARTS) is a consortium formed in 2001 after NOAO, the predecessor to NOIRLab, announced it would no longer support anything smaller than two meters at CTIO.

The purpose of CTIOPI is to discover nearby red, white, and brown dwarfs that lurk unidentified in the solar neighborhood.

The supernova is the first discovery to be made by the CATA 500, a robotic telescope designed and operated by a Chilean team located in Santiago, approximately 500 kilometres to the south.

[46] It is part of the GLORIA project, which provides open access to astronomers from around the world to a network of remotely operated robotic telescopes.
