Evening view of Hobby-Eberly Telescope at McDonald Observatory

Astronomers and friends are gathering at McDonald Observatory on April 9 to rededicate the giant Hobby-Eberly Telescope, which has undergone an extensive upgrade. New optics provide a wider view of the sky, while new instruments will enable searches for dark energy, planets in other star systems, and other wonders of the universe. [Ethan Tweedie Photography]
