Xyalala is an exoplanet system in the so-called M-dwarf star constellation. Located 2,400 light years from Earth, the system contains a sun-like, low mass star and an almost Earth-size transiting planet. One hundred two years ago it was the target of a scientific study which led to the discovery of seven additional planets to the system using precise radial-velocity measurements of the star.

On August 25th, 2364, I set out towards Xyalala system. During the three-week-long trip, I visited four of the new planets: RYU0444Bb, TYJ0824b, TYJ0429b, and RYU0508b.

Three days before reaching the system, I launched my new telescope, the 50/70mm Sumilux with 0.3" mirror, the largest optics I’ve ever mounted on a space telescope. My goal was to reach the habitable zone of the sun, where a planet orbiting a sun-like star with a mass less than three times that of Jupiter might be able to produce liquid water. (I.e. a water world!) This would be a good place to find potential signs of life.


When I was young, I used to say that I was from a different planet. This planet had the weird name x-ych-alala-alala which I abbreviated to xyalala here to see what the AI would come up with.

I was expecting it would write a Wikipedia-like article about the planet, but the most interesting part was when the AI started writing about visiting the system. This prompted me to add the “On August 25th…” part in the center.

The whole thing had several iterations with lots of scientific nonsense. This nonsense is still somewhat present, but at least there is a bit of coherence. A 0.3 inch mirror is probably not the “largest optics ever mounted” :-)

GPT-3 would probably produce better results than this.
