First life-friendly exoplanet may not exist after all

Type the name “Gliese 581 d” into a search engine, and you’ll find hundreds of tantalising images of an Earth-like world. The exoplanet has been a top contender for the most life-friendly world beyond our solar system since it was discovered in 2007. There’s just one problem – it probably doesn’t exist.

We’ve really got to get better at this space stuff - seriously.
