You'd be surprised. Not an expert, but...

We are able to study the chemicals that are present from sources very far away based on the light spectrum that we pick up. They'll be looking for chemicals that we know are commonly associated with life. For example, diatomic oxygen is one of those that would be an indicator. The holy grail would be figuring out how to detect chlorophyll - if they can find that one, it's gonna make headlines.

Here's an article that explains it a bit:
