Hi Peter,
This is a fantastic discovery, a system with 7 Earth sized planets! I expect we will learn some of the real science behind this discovery and the future research of this system at the Winchester Weekend. Prof Didier Queloz is giving the Alfred Curtis Memorial Lecture, and he is one of the authors of the Nature paper announcing this latest discovery. Brilliant timing by the meeting organiser!
I agree the media tends to get carried away, and social media even more so. It is a shame as I think the hype can miss the excitement that we do not know everything yet. So there will be lots of discoveries along the way as we learn about this planetary system and others which are no doubt waiting to be discovered.
Cheers,
Andy
