Unfortunately, we don’t know what these small, rocky planets look like—even the largest telescopes currently in development won’t be powerful enough to resolve surface features. But as the instruments get more powerful still, one research team is wondering whether we might be able to detect mountains on an Earth-sized planet. Under the right circumstances, they argue, these large surface features should show up.
