Astronomers Detect a Possible Signature of Life on a Distant Planet

> While inspecting K2-18b, Dr. Madhusudhan and his colleagues discovered it had many of the molecules they had predicted a Hycean planet would possess. In 2023, they reported they had also detected faint hints of another molecule, and one of huge potential importance: dimethyl sulfide, which is made of sulfur, carbon, and hydrogen. On Earth, the only known source of dimethyl sulfide is life.

Intriguing.

It's absolutely amazing that we can even figure out molecules at that distance. I'm sure it's accurate but it's so sciency to me that it might as well be made up entirely. I can't begin to fathom that process.
