Víctor M. Blanco 4-meter Telescope

The Víctor M. Blanco 4-meter Telescope was commissioned in 1974. It is a near twin of the Mayall 4-meter telescope on Kitt Peak. In 1995 it was dedicated and named in honor of Puerto Rican astronomer Víctor Manuel Blanco. It is also part of the Dark Energy Survey (DES), a visible and near-infrared survey that aims to probe the dynamics of the expansion of the Universe.
