First Extrasolar Object Observed Racing Through Our Solar System

Enigma2175 writes: For the first time, scientists have observed an object they believe came from outside our solar system. The object is in a hyperbolic orbit that will send it back into interstellar space. From Space.com: "The object, known as A/2017 U1, was detected last week by researchers using the Pan-STARRS 1 telescope in Hawaii. 'It's long been theorized that such objects exist -- asteroids or comets moving around between the stars and occasionally passing through our solar system -- but this is the first such detection,' Chodas added. 'So far, everything indicates this is likely an interstellar object, but more data would help to confirm it.' It's unclear what exactly this thing is. When A/2017 U1 was first spotted, it was thought to be a comet (and was therefore given the moniker C/2017 U1). But further observations have revealed no evidence of a coma -- the fuzzy cloud of gas and dust surrounding a comet's core -- so the object's name was amended to its current asteroidal designation."
