A powerful new observatory is the best hope yet for finding the elusive Planet 9, a large planet that some scientists say is hidden in our solar system.
For a long time, the Catholic Church rejected scientific findings that conflicted with its doctrine, even persecuting Galileo. Now the Vatican looks to promote its observatory as a bridge to science.
The observatory suddenly closed, with little explanation, for 11 days in September, fueling rumors its shutdown was due to aliens, UFOs, or government surveillance.
