Supermassive black holes at the hearts of distant galaxies – and even our own sun – shine in the new movie. 

This month marks the 30-year anniversary of the first website in North America, launched at SLAC. In this Q&A, one of the Wizards recalls the motivation that spawned the development and how it has changed the work of scientists.

From the invisible world of elementary particles to the mysteries of the cosmos, recipients of this prestigious award for early career scientists explore nature at every level.

Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.

Our best model of particle physics explains only about 5 percent of the universe.

Astrophysicists use a catalog of extended gamma-ray sources spotted by Fermi spacecraft to home in on mysterious properties of deep space.

A team of electrical designers develops specialized microchips for a broad range of scientific applications, including X-ray science and particle physics.

Presented by Eric Charles. A single gamma ray carries millions of times the energy of a single photon of visible light.  This means that gamma rays are produced only in the most convulsive environments in the universe –  pulsars spinning...

By capturing the most energetic light in the sky, the spacecraft continues to teach us about the mysteries of the universe.

The era of multi-messenger astronomy promises rich rewards—and a steep learning curve.

Sensitive gamma-ray “eye” on NASA’s Fermi space telescope continues to provide unprecedented views of violent phenomena in the cosmos.
