OUMUAMUA: FIRST KNOWN VISITOR FROM ANOTHER SOLAR SYSTEM | All About OUMUAMUA | Ansamtech
The nature and origin of Oumuamua, the first known visitor from another solar system, have become more mysterious after scientists claim to have ruled out a major explanation. Researchers had suggested earlier this year that the origins and molecular structure of Oumuamua could be explained by it being a hydrogen iceberg. Among other mysteries, that would help solve the question of how it was able to power itself through such distant space, since pure hydrogen gas would have been able to push it like a rocket. That explanation was useful to the scientists who have spent years puzzled by Oumuamua, after it was first spotted travelling nearly 200,000mph through our solar system in 2017. It sped up as it went on its journey, without any clear explanation, and seemed to behave somewhere between an asteroid and a comet, though it didn't fit either category and it remains mysterious where it has come from. But a new paper from researchers at Harvard and the Korea Astronomy and Space Sc...
