New issue: The galaxies that shouldn't exist

Who doesn’t love a good mystery? There’s nothing better than uncovering the clues to crack a case. A missing button here, a crooked rug there, and does that painting look fake to you? But when it comes to solving the mysteries of the Universe, things are even more complicated. We may now have the James Webb Space Telescope at our disposal, but the more it shows us, the deeper these mysteries become. It’s shown us a surprising number of gigantic galaxies lurking in the oldest corners of the Universe. The trouble is, to reach the sizes we’re seeing, they must have formed earlier than we think is possible. As far as our understanding of cosmology is concerned, finding these galaxies is like finding someone murdered inside a locked room. Luckily, there's a team of astro-sleuths on the case, and they’re using all their deductive skills to explain why we’re finding so many of these very big, very old galaxies – and if they’re really as weird as they appear to be.
