Astronomers have confirmed thousands of planets outside our Solar System, but not a single exomoon. New research is bolstering the case for a suspected exomoon first detected last year, but scientists say the evidence is still not definitive.

Every once in a while, our planet captures a “mini-moon”, a tiny asteroid that hangs out in our orbit for a bit before venturing back into the depths of space. New research suggests these small, temporary natural satellites carry tremendous scientific and commercial opportunities — but the trick will be in finding them.
A favourite pastime of astronomers is to debate the origin of Earth's Moon, but despite decades of research, they don't seem to be any closer to reaching a consensus. Scientists have now added a new theory to mix - and it's weird as hell. The Moon, they argue, formed inside a gigantic doughnut-shaped cloud of vaporised rock that would eventually condense into the Earth.
