Not only is this interesting in the sense that it is great science, but it also shows that we should always check and double check our generally accepted assumptions.
As New Scientist states
As Earth shows, the Goldilocks zone is
no ultimate judge of habitability, something exoplanet researchers have
known for years. As well as clouds, volcanic activity or the location
of other moons or planets in the solar system, may be important for life
to develop on planets like Earth
As New Scientist states
Shockingly, Earth – which used to be smack-bang in the
middle of our sun's habitable zone – is now a scant million kilometres
away from the warm edge, so almost too hot for liquid water. Of course,
we know Earth is robustly life-friendly – the mismatch is probably
because neither definition accounts for clouds, which reflect sunlight
away from Earth.
