It also protects the moon's equatorial regions, where the field lines are closed, from energetic particles.

They are also closely linked with the acceleration of solar energetic particles.

Its like you have a few very hot, very energetic particles, but really not much in the way of mass.

Can there be still more energetic particles in existence?

Low atomic number also makes beryllium relatively transparent to energetic particles.

And there were some much more energetic particles: almost like cosmic rays.

The net process is that the rotating black hole emits energetic particles at the cost of its own total energy.

Computer calculations done several years ago revised downward the number of energetic particles, or neutrons, that were given off.

But all those energetic particles are travelling much more slowly (around 710km per second), and so they'll take 24---48 hours to reach us.

Although the tube walls have a greater stopping power than an end window, they still allow these more energetic particles to reach the fill gas.
