We missed the rain today, caught the warm sunlight.

I listened to an "in our time" podcast about exo-planets.

hot-jupiters, brown dwarfs.

brown dwarfs are sort of failed suns, so are at the centre of solar systems, but they have weather, like clouds, that can be seen.

since the early 1990's , when we started observing exo-planets, we have discovered about 900, for definite, and the solar systems are different to one another.

and there are a lot of suns, and we are not that good at detecting exo-planets, it's difficult.

I love science.
