Episode notes

In a solar eclipse, the sort of bit that shines out over the outside of what the moon blops is where corona comes from. The only time you'd hae ever really been able to see that is during an eclipse, because otherwise it's too faint to see. But there are also other tools that developed in the twenties called coronographs,. which are essentially like little artificial moons inside telescopes that block out the sun. And they're very interested in the corona. So this article was trying to run through some of the possible ways in which the sun's korona could be created - and then try to figure out what’s going on.

How tiny seed-like sensors could monitor the environment, and the latest from the Nature Briefing.
