Here's a contrarian, but interesting, take from Wired. We shouldn't be talking about the blue moon, supermoon or blood moon, it claims.That's because the blue moon isn't something you can see. The blood moon is a somewhat dramatic name for a lunar eclipse, which already has its own scientific term. And supermoons come round so often that they're not all that interesting.Which is all true. But tonight's moon will look very nice. And just that fact is enough to get people engaged with astronomy and the movement of our neighbours, which is important. That's why important space agencies including Nasa are getting involved in tonight's goings on, even if they don't actually tell us all that much about astronomy or the moon.That, to be fair, is something of the conclusion that Wired comes to:"It’s going to be great, I can assure you. It’s an eclipse, for heaven’s sake, regardless of the semantics. And it almost certainly won’t be the end of the world."
