NASA’s James Webb Space Telescope is raising big questions about the early universe. In its first images, JWST captured what appeared to be huge galaxies in the ancient universe. In fact, those galaxies looked much too big to fit scientists’ current theory of how the universe grew up. This has raised some concerns that the history of the early universe needs to be rewritten. But a new look at old data from the Hubble Space Telescope tells another story.

My favorite coffee shop keeps a sign behind the espresso machine: “Is Mercury in retrograde?” The barista uses a flip-style “yes/no” just below to indicate each day’s status. I’ve noticed that her greetings tend to be more along the lines of, “Be careful out there!” when the sign says yes versus, “Hey, enjoy the gorgeous day!” when the sign says no. I instinctually roll my eyes at that sign. Her cappuccino is the best in town, though, so I keep coming back.
