The James Webb Space Telescope isn’t actually complete yet, but its mirror is now together. As has been stressed repeatedly in places like Twitter, this sight isn’t an unfamiliar one, but this time it’s not a model or a computer animation… it’s the real thing. And that means the James Webb Space Telescope (JWST) is…
By “second-wave planets” I mean a planet forming long after the protoplanetary phase of the star system (it’s not the technical term, and I’m not even entirely sure there IS one). Can that happen? It’s entirely possible, and astronomers may have now seen evidence of that.
Is this the end of Science? That is what one scientist connected with CERN was saying in a TED talk in December. Your knee-jerk reaction (and Bettridge’s Law of Headlines) says the answer should be a confused “no”. In reality, the headline is certainly overblown, but the problem being highlighted is a real one.
A little over a month ago, Caltech astronomers Konstantin Batygin and Mike Brown announced new calculations that suggest there IS a ninth planet in the outer solar system. The planet has to be very distant and can’t be very big or hot, otherwise we would have seen it already. Of course, to prove it’s more than just a mathematical curiosity, you need to find it. Now other astronomers are starting to weigh in.
