A new telescope, part of an international effort to develop and build the world’s largest, most sensitive gamma-ray detector, was unveiled to the public Thursday (Jan. 17, 2019) in a ceremony at the Whipple Observatory on Arizona’s Mount Hopkins.

Decades ago, the aspiration to build a kilometer-scale neutrino detector at the South Pole seemed farfetched; today, we celebrate the 5-year anniversary of this incredible achievement.

Building a cubic-kilometer telescope at the South Pole seemed a chimera even for some of those involved in the project. The goal was simple in words but seemingly impossible in practice: 86 boreholes, each 60 cm in diameter and 2,500 m deep, had to be drilled and instrumented in seven austral summer seasons.

High on a sleeping Mexican volcano, a new particle astrophysics observatory is about to blink to life, commencing an all-sky search for very high energy gamma rays — a search that could greatly expand the catalog of known gamma ray sources and chip away at the mystery of the cosmic rays that constantly bombard our planet.

Last week, Nature published an article on the High-Altitude Water Cherenkov Observatory, a gamma-ray observatory near Puebla, Mexico. WIPAC at UW–Madison is a collaborating institution. The article details plans for HAWC, scheduled for completion in fall 2014. When complete, it will consist of 300 water-filled tanks housing particle detectors.
