telescopes

A camera lens often used by wildlife and sports photographers has helped astronomers learn about dark matter and galaxy formation.

The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.

What could cause galaxies millions of light years apart to all spew material in the same direction?

As physics prepares for ambitious projects like the Large Synoptic Survey Telescope, the field is seeking new methods of data-driven discovery.

Three “extremely large telescopes” poised to begin observations within a decade could help answer some of the universe’s oldest and best-kept secrets.
