ROME (AP) — Pope Leo XIV marked the 56th anniversary of man’s arrival on the moon Sunday with a visit to the Vatican astronomical observatory in Castel Gandolfo and a call to astronaut Buzz Aldrin. This was Pope Leo’s first visit to the observatory, founded in 1891 by Leo XIII. The Vatican Observatory has generated top-notch research from its scientist-clerics, drawing academics to its meteorite collection, which includes bits of Mars and is considered among the world’s best. Later Sunday, the pope called astronaut Buzz Aldrin, who shared with Neil Armstrong the historic 1969 moonwalk. “This evening, 56 years after the Apollo 11 moon landing, I spoke with the astronaut Buzz Aldrin,” Pope Leo wrote on his X account.
