How do you build a moon? :first_quarter_moon:
Thanks to the James Webb Space Telescope, we’ve just taken the first-ever look at the chemical ingredients inside a moon-forming disk around a distant world called CT Cha b — 625 light-years away. With carbon-rich compounds swirling in a cosmic kitchen of gas and dust, scientists believe this may be our first glimpse at moons being born in real time. Could this explain how our own moons formed? And what does it mean for the countless other planets out there?

:telescope: Watch to discover how Webb is rewriting what we know about the universe — one moon at a time.

00:00How do you build a moon?
00:01Well, for the first time ever, we might actually know the recipe.
00:05NASA's James Webb Space Telescope just captured the most detailed look
00:09yet at a moon-forming disk around a planet 625 light-years away.
00:13This mysterious world is called C.T. Chabi, 17 times the mass of Jupiter,
00:18and it's either a massive planet or a baby brown dwarf.
00:22Orbiting a very young star, this giant is wrapped in a swirling disk of gas and dust.
00:27And that's where it gets exciting.
00:29Webb's infrared eyes have spotted a cocktail of chemicals.
00:32Acetylene, benzene, carbon dioxide, ethane, hydrogen cyanide,
00:38basically everything you'd need to cook up some moons.
00:41What's wild is this is the first time we've ever measured the actual ingredients in a moon-making disk.
00:46Scientists think C.T. Chabi's moons are still forming,
00:49right now in a cosmic kitchen 41 billion miles from its star.
00:54It's far enough from the glare that we can watch this process live,
00:57for the first time in human history.
01:00And guess what? This might just be the first of many.
01:03Because if moons outnumber planets, as we suspect,
01:06this tiny window could open the floodgates to understanding how our own moons came to be.
01:10Stay tuned. The universe is just getting started.
01:13The universe is just getting started.
