It is the birth of neutrino astronomy. For the first time, astrophysicists can detect extraterrestrial neutrinos in the ice in the South Pole. Neutrinos are the most common and also most mysterious elementary particles. Since these particles are invisible to us, their mass is unknown. Also, they are not electrically charged and rarely interact with other matter. Each of the tiny neutrinos is a potential messenger with information about its origin....

This programming explores theories of the Universe exploding from an infinitesimal speck to create matter, radiation, time and space. In the first trillion-trillion-trillionth of a second, the cosmos grew a hundred million times to less than the size of an atom. Then, in another instant, the Universe was the size of a galaxy. Now, billions of years later and strung along vast filaments, our Universe has some 50-billion galaxies that continue to expand...

How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create standards. Distances are so vast they are described in light years – the distance light travels in a year. Nearby stars are measured by trigonometry—the technique of parallax. Farther out, astronomers use so-called “standard candles”, the ‘Type Ia supernovae’ is the...

The history of cosmic ray research is a story of scientific adventure. For nearly a century, cosmic ray researchers have climbed mountains, ridden hot air balloons, and traveled to the far corners of the Earth in the quest to understand these energetic particles from space. They have solved some scientific mysteries - and revealed many more. With each passing decade, scientists have discovered higher-energy, and increasingly more rare, cosmic rays....

Particle physics doesn't just expand our horizons; it helps explain the universe by examining the nature of matter, both seen and unseen. In this video lecture from the 2009 Falling Walls Conference, hear from Rolf-Dieter Heuer, who works with the Large Hadron Collider at CERN. He discusses their quest to provide experimental evidence either confirming or refuting the existence of the Higgs boson, an elementary particle predicted to exist by the Standard...
