I have a confession to make.
Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before , but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does.
