In the late 1940s, the US Naval Research Laboratory used a few German-built V2 rockets to study cosmic rays from above Earth’s atmosphere. To do this, a nitrogen-powered cloud chamber was ...

The discovery of Eos, the closest known molecular cloud to Earth and one of the largest structures in the night sky, hints at ...

Eos, a newly discovered hydrogen cloud just 300 light-years from Earth, offers a rare look at hidden star-forming regions.

For decades, astronomers were certain that half of the ordinary matter in the universe — protons and neutrons, the building ...

Cosmic rays may offer an out-of-this-world answer ... "But that process would require a very strong electric field in the cloud, and that has never been measured." In fact, Shao added, the ...

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 ...

The cloud, named Eos, is chock-full of molecular hydrogen and possibly rife with star-forming potential in the future.

Using NASA’s Chandra X-ray Observatory, astronomers have uncovered the likely cause behind a mysterious fracture in one of ...

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.

Scientists are using cutting-edge techniques to track water ice on the Moon—an essential resource for future space missions.
