Futurism

For over a century, astronomers have wondered if there’s an extra planet in our Solar System that we haven’t been able to detect yet. It seems like we get another “Planet Nine” candidate — formerly known as Planet X, before Pluto was demoted — every few years, and none have been confirmed. But the possibility has never quite been put to bed, either.
Now, an international team of researchers have made a new detection that they say could be a sign of a hidden world — by, poetically, unearthing what went overlooked in very old data.
