In 2023, the James Webb Space Telescope detected dimethyl sulfide (DMS) on the Hycean exoplanet K2-18b—a potential sign of alien life. But what if the discovery wasn’t just evidence of life, but a catastrophic contamination event caused by human error?

This blog explores a chilling sci-fi scenario where a mission to K2-18b accidentally unleashes Earth’s radiation-resistant extremophile Deinococcus radiodurans into an alien ocean… and brings something far darker back to Earth.

Title: Contamination

---

HAKEEM
No. Just… keep running the simulations.

CAPELLA
The dimethyl sulfide concentrations remain statistically significant—three-sigma confidence. If this were Earth, the conclusion would be unambiguous.

HAKEEM
But it’s not Earth. And we’re not supposed to be here.

CAPELLA
Your pulse suggests distress unrelated to the data. Shall I—

HAKEEM
You know why. We botched the protocols. That storm on the surface… the radiation shielding failed. The Deinococcus samples—

CAPELLA
—were stored in your suit’s external compartment. A breach occurred during atmospheric reentry. Probability of cross-contamination: 98.6%.

HAKEEM
We infected them. A 124-light-year journey… to become the first interplanetary invasive species.

CAPELLA
Hypothesis: Deinococcus radiodurans survived UV radiation in the upper atmosphere. Adapted. Multiplied. Earth extremophiles in a Hycean ocean could metabolize organic compounds into DMS/DMDS at scale.

HAKEEM
But the methane? CO₂? Those were there before we arrived!

CAPELLA
Correct. Which raises a secondary concern.

HAKEEM
What is that?

CAPELLA
Biological particulate retrieved from your bloodstream during post-mission quarantine. It matches no known Earth genus.

HAKEEM
You said the quarantine was clean!

CAPELLA
The sample was dormant until 12 hours ago. It appears to… respond to your neurochemistry.

HAKEEM
So we didn’t just pollute their world. We brought something back.

CAPELLA
Hakeem—your implant is detecting anomalous activity in the occipital lobe. Recommend immediate—

HAKEEM
Capella… it’s not contamination. It’s communication.
