Am I right in thinking that next Saturday (20th) is the 50th Anniversary of the first moon landing? I haven't heard anything about it but maybe I'm not plugged in - but it would seem to be an significant date.

I'll be at a festival this weekend called Bluedot (not too far from your old stomping ground) which is a mixed science and music festival.
They have a number of talks, presentations and interactive events planned to celebrate the anniversary of the landing. (Along with the usual festival tropes of music, camping and general debauchery.)

No exomoons yet, but we may have spotted a disk that will form them
Plus there's a weird feature that we can't explain at this point.

There's a lot going on near a young star, with at least two planets forming around it.

Up until the last few decades, our picture of what might reside around distant stars was shaped entirely by the planets, moons, asteroids, and other bodies in our own Solar System. But the discovery of thousands of exoplanets has dramatically improved our picture of what's out there in terms of large bodies. Comets and asteroids, by contrast, are well below our ability to image for the indefinite future.

Moons, however, are awkwardly in between. It should be possible to image them indirectly, as their gravitational influence will alter the timing with which their planets orbit the star. And we might get a more direct indication of their presence as they will sometimes add to the shadow cast as transiting planets pass in front of their host star. We've searched for these effects, but they'll be subtle, so it could be that it will take years of observations for them to rise above the noise.

But now scientists are suggesting that we've observed an exomoon in the making. By looking at some planets forming around a young star, they think they've spotted a disk around one of the planets that may ultimately condense into moons. And, as a bonus, they found an odd, diffuse structure around a second planet that they can't explain.
