Check out the great @nytimes overview of UT Astronomy's work to understand Dark Energy from some of the darkest skies in the US! 🔭

[McDonald Observatory @mcdonaldobs]

“‘Dark energy’ is the phrase we use to represent our ignorance of how the universe is expanding, but it may not be dark.
It may not be energy.”
- @UTAustin's Dr. Karl Gebhardt, discussing the work of the HETDEX team, in a @nytimes article - out today!
