“Most promising signs yet” of alien life on a planet beyond our Solar System

A bit clickbaity of OP to skip the operative word ‘promising’ signs of life.

To be fair, the original title goes above HN's character limit, but the omission is almost worthy of a flag, in my opinion...

Better alternatives:

- Promising signs of alien life found on a planet beyond our Solar System

- Astronomers have found promising signs of alien life on an extrasolar planet

This should be higher up

And it isn’t actually signs of life. The first paragraph:

> Astronomers say they've found "the most promising signs yet" of chemicals on a planet beyond our Solar System that could indicate the presence of life on its surface.
