Question: Have you made any recent discoveries concerning planets in outer space?

We made some calculations to find out where Earth-like planets with right kind of atmospheres can exist. Now we know that there are many planets that are not too hot, not too cold and are at a right distance from their star.
We call them “potentially habitable planets”. That means, these planets may have life on them (we are not sure yet).
