The SDSS map is shown as a rainbow of colors, located within the observable Universe (the outer sphere, showing fluctuations in the Cosmic Microwave Background). We are located at the center of this map. The inset for each color-coded section of the map includes an image of a typical galaxy or quasar from that section, and also the signal of the pattern that the eBOSS team measures there. As we look out in distance, we look back in time. So, the location of these signals reveals the expansion rate of the Un

Physics & Astronomy

Students explore yesterday, today and tomorrow in search of a deeper understanding of the natural world—from the mysteries of dark matter to the smallest machines possible, from the complexity of life to nature's strongest forces.

The Cosmos

The Cosmos

From the mysteries of dark matter to the secrets hidden in our own solar system, astrophysics probes the galaxy of unanswered questions.

Nanoscience

Nanoscience

At the size scale of an atom, researchers manipulate nano-particles to explore the world of quantum mechanics and to build the smallest machines possible.

Probing Life

Probing Life

Biophysicists study the complexity of life by using the laws of physics and the power of math to analyze patterns in living things, from epilepsy to signal processing.

Nuclei and Particles

Nuclei and Particles

The nuclear force is the strongest found in nature. From questions of how protons and neutrons are bound in nuclei (or neutron stars) to the interactions of quarks and gluons, this is strong stuff.
