In the classic science fiction novel, Venus on the Half Shell by Kilgore Trout, the question of how intelligent life evolved (at many different locations) in The Universe is raised, and pursued by the novel’s protagonist.

Now, if you’ve read Kilgore Trout’s masterpiece, you will know why this is especially funny. If not, well, you have to read this book.
Anyway, from New Scientist:
An unusual star may have swallowed its stellar companion and burped out a planet-forming cloud as a result, a new study reports.
The star, called BP Piscium, is surrounded by a thick disc of gas and dust from which it appears to be sucking up new material at a prodigious rate.
These properties are typical of young stars, but BP Piscium appears to be much older, based on the weak signs of lithium in its light spectrum. Younger stars have plenty of lithium, but it gets destroyed as stars age.
Up to you.
