Astronomers have found the closest solar system to our own to be discovered in nearly a century - the third-closest ever found, in fact.
NASA's Kepler mission has for the first time discovered multiple planets orbiting a pair of stars, showing it's possible for more than one planet to be formed and survive in such a chaotic environment.
Since the 2010 discovery of four stars 300 times as massive as our sun, astronomers have been scratching their heads over how they could have come to exist.
A team of astronomers has discovered four pairs of stars that they thought couldn't exist, with the stars in each pair orbiting one another in less than four hours.
A population of old, volatile stellar black holes has been discovered, following an 'extraordinary outburst' from one located in a nearby galaxy.
We normally think of stars as hot - but scientists using ESO's Very large telescope say they've found a pair of cool brown dwarfs, one of which is no hotter than a sauna or a cup of tea.
Human beings are hopelessly binary. Most perceive the world as a static equation populated by two, absolutist variables.
