Webb Telescope Unveils TOI-421 B: A Hot Sub-Neptune’s Cosmic Secrets!

Hey space nerds! NASA’s James Webb Space Telescope just dropped a mind-blowing discovery about TOI-421 b, a sizzling sub-Neptune exoplanet 244 light-years away. This bad boy’s atmosphere is clear (no hazy clouds!) and packed with water vapor, maybe some sulfur dioxide, and a whole lotta hydrogen. At 1,340°F, it’s hotter than your average sub-Neptune, and it’s orbiting a Sun-like star, making it a total cosmic outlier. Why does this matter? It’s rewriting what we know about how these weird, gassy planets form and evolve—plus, it’s a peek into worlds we don’t have in our solar system. The Webb Telescope’s epic spectrum data is basically a chemical fingerprint of TOI-421 b’s vibes, and we’re here for it. Wanna geek out over the details? Check out the full scoop here.
