Just how big can a super-Earth get while staying ‘habitable’?

Of the thousands of exoplanets discovered so far, the most common are “super-Earths” — worlds bigger than Earth but smaller than Neptune. Some of these planets even lie within the habitable zones of their parent stars, meaning the conditions there might be right to host liquid water on their surfaces. 

But could these giant, rocky exoplanets actually sustain the conditions for life? Or is life limited to smaller planets like our own? Ultimately, only future observations will give us a conclusive answer. But in the meantime, the question gives us a perfect opportunity to explore the limits of our understanding of where life might find a home.
