In Texas, portal to early universe enabled by largest dark-sky reserve on Earth
Astronomers at the McDonald Observatory in West Texas are using the Hobby-Eberly Telescope to study galaxies 10 to 12 billion light-years away, leveraging the world's largest dark-sky reserve to minimize light pollution. The HETDEX project aims to understand dark energy, which began accelerating the universe's expansion two billion years after the Big Bang. Data collected from 2017 to 2024 may soon yield key insights into the universe's fate. The region’s pristine night skies also support broader dark-sky conservation efforts amid growing light pollution.
