It may sound cliche, but the question ‘Are we alone?’ is still one that captures the imagination of many people, including of course, scientists. With the now regular discovery of exoplanets orbiting other stars, the prospect that there may be other intelligent life out there […]

'Weird Object' Discovered Beyond Neptune: A Clue in the Quest for Planet Nine?

The newly discovered object called Niku is a real oddity (artist’s conception). It is also part of a group of many such objects far past Neptune in the outer Solar System. Image Credit: ESO/L. Calçada/Nick Risinger

For the most part, the Solar System seems to be a rather well-ordered place; the planets, dwarf planets, […]
