Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit over its entire lifetime. Yet, despite decades of observations, key mysteries remain unsolved: What powers the prompt emission? What is the […]

Before we get to Mars, we’re going to have to practice. And develop radical leaps in technology, but also practice. A Mars mission will be utterly unlike anything attempted by humanity. We’re talking about a group of settlers, maybe as few as an initial team of four, traveling over a hundred million miles away from […]

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe’s mass. As it cannot be detected and studied using conventional experimental techniques, the nature and composition of dark matter have not yet been uncovered.
