Title: Dear CA # 106: Articles On Particles

Organization: Cheap Astronomy


Description: Small things, very small rocks, particular rocks… and astronomy on the ISS.

Dear Cheap Astronomy – What’s a particle?

Probably the best answer is that particles are those things detected by particle detectors. Unfortunately this can range from dust detected by atmospheric particle detectors to those things detected within the large hadron collider – which are a special category of those things that particle accelerators accelerate and particle colliders collide.

Dear Cheap Astronomy – What sort of Astronomy is done on the ISS

Conducting astronomy from a moving platform has it challenges. Of course the Earth itself is a moving platform, both rotating on its axis and also orbiting the Sun – but those motions are relatively slow. You can set a cheap backyard telescope, like our own Sky Station 1, still-operational after all these years, and keep observing Saturn – just shifting the scope every now and again to keep it in view.

Bio: Cheap Astronomy offers an educational website where you’re only as cheap as the telescope you’re looking through.
