Presenting the results of an analysis of a habitable zone planet. Signal of life detected.

These molecules are known to be biosignatures on earth.

There's no CO or NH3 detected, so we're not sure what life would look like under those conditions. Still open questions.

DMS and DMDS are the biomarkers. They previously detected CH4 and sulfur.

There are other planets that seem to show this signal. (My takeaway/guess: life is common throughout.)

Marvel at the data, this is the first time we've seen this.

The laws of biology are cosmic in nature. You are looking at a living sky.

When you look at the sky it's a big change from seeing everything as inanimate to being aware that there is life out there (I'm paraphrasing, he was much more poetic).

His presentation has concluded; now it's questions.

TL;DR life has been detected. We are not alone 💯
