[00:00:00]There is a planet 124 light years from us called K2-18b.

[00:00:08]The new telescope detected a chemical in its atmosphere called dimethyl sulfide.

[00:00:15]On Earth, that chemical mostly comes from ocean plankton, from living things.

[00:00:24]The detection is not yet confirmed, but it is the strongest hint of biology beyond Earth so far.

[00:00:34]So, are we about to meet someone?

[00:00:37]And what if the answer is something we never expected?
