Mercury crossed in front of the rising sun on Monday morning, a rare event seen from Earth only 13 or 14 times each century.

The transit of Mercury, as the phenomenon is known, lasted for seven-and-a-half hours. Slooh, a space broadcasting site, hosted a livestream of Mercury's movement, with commentary from experts including Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell.

"The transit of Mercury reminds us that all of the planets, including Earth, are in rapid and perpetual motion," said Paul Cox, Slooh's host, in a press release.
