How many gamma photons are in the galaxy,
and what can we know about the distribution?
Which kind of process can absorb them?

IIRC, there's been some recent work on mapping cold, dark clouds by studying their wide borders' soft x-ray emissions where particles are excited by cosmic rays...
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
