There were always random failures of pixels when some especially powerful particle hit a de- tector element.

These particles can hit the Earth within 15 minutes to 2 hours of the solar flare.

When the particles hit the aerogel, they left tracks in the material.

If a particle hits an atom with enough energy, it might break one of the electrons away.

When the particle hits the boundary it reflects from it without loss of speed.

Every particle in free space hits that nose like a cosmic ray.

The particles hit molecules in the air and knock off electrons to form ions.

"Do you know what the effects will be, when the particles hit us?"

In either case, the particles hit the walls and are stopped.

After speeding through space, the particles loop around Earth's magnetic fields and hit air molecules, causing them to glow.
