Why is it so darn weird? But a team of scientists has announced they may have made major progress on that second question, narrowing down the object's origins to just four stars. The research is based on data gathered in June that suggested 'Oumuamua wasn't just hurtling through space willy-nilly. Instead, it seemed like when the object was near the sun, it picked up a bit of extra speed, as if, like a comet, it carried something like ice that could turn to water vapor and propel the object forward a little faster than usual. Accounting for that fact nudged 'Oumuamua's entry trajectory into our solar system a bit. (Scientists only spotted the object on i...
