One of the strangest astronomy stories of the past few years is the sudden appearance of what scientists believe is the first interstellar object ever to be detected in our solar system. The cigar-shaped space rock known as Oumuamua puzzled scientists who attempted to explain what it was and where it may have originated, and there are still more questions than answers.
At first, researchers couldn’t decide whether or not it was an asteroid or a comet, and then debate raged over why Oumuamua appeared to actually speed up after it swung around the Sun and headed back into space. That last point is still the subject of ongoing research, and a new theory to explain its acceleration is set to appear in Astrophysical Journal Letters.
