Could our solar system have been temporarily exposed to an enhanced flux of cosmic-rays at some point in the ancient past?

The "needle in the haystack" discovery of a powerful explosion from a mysterious unknown object outside our galaxy has ...

At the CERN laboratory in Switzerland, particle physicist Jasper Kirkby studies the link between aerosols, cosmic rays and cloud formation, using the data to inform climate models. “It’s ...

In a fractal zeta universe of bifurcated, ripped spacetime, the Millikan experiment, the quantum Hall effect, atmospheric ...

However, much closer to home, you can actually build your own cloud chamber and see cosmic ray trails yourself for about $100! Here’s instructions. What do we know about cosmic rays, and what remains ...

Dr. Millikan recognized this ray ten years ago and called it the cosmic ray. He found that it penetrated 50 ft. of lead, 200 ft. of water. Last year Professor Auguste Piccard, cruising into ...

Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes ...

Cosmic rays? Or maybe just electric charges. Put a cup on and start experimenting. If you want to reliably see cosmic rays, build a cloud chamber. All you really need is a plastic bottle.

The Tarantula Nebula, also known as 30 Doradus, is revealed in an unusual light in this exceptionally deep Chandra X-ray ...

The cloud chamber detects secondary cosmic rays and radioactive decays by making alcohol clouds along the particle paths through the chamber. Particles ionize alcohol molecules as they pass through ...
