The myth of the changeling exists in almost every medieval European culture. Folklore says fairies would steal away babies and replace them with an identical creature, and parents would be tricked into raising something that wasn’t their own until they slowly realized something was amiss. It’s a classic fairy tale. It’s dark, fantastical, and rooted in truth: many folklorists believe the changeling myth exists to explain child mortality and birth defects as the work of fairies.

While today’s culture may not include this folklore, the need for explanation and reason in one of the most stressful stages of a person’s life, early parenthood, still persists, and so does the need for fairy tales. The Changeling, Apple TV+’s new horror fantasy series, takes the classic structure of these stories and twists it into the most unique, dreamlike modern fairy tale we’ve ever seen on television.

If there’s life on any of the habitable-zone TRAPPIST-1 worlds, JWST should be able to see signs of it in the planet’s atmosphere, a recent study says.

The reverse is also true; if an alien civilization out there somewhere has their own super-sensitive infrared space telescope, they’ll be able to see our effects on our planet’s atmosphere. Johns Hopkins University astrobiologist Jacob Lustig-Yeager and his colleagues turned measurements of Earth’s atmosphere into simulated data from TRAPPIST-1e and found that even in the messy, low-resolution view of a planet 40 light years away, JWST could pick out molecules that reveal the presence of life and advanced technology (by which we mean pollution).
