A Tide for the Ages and a Night to Remember

An extreme lunar perigee nearly simultaneous
with the full moon of January 4, 1912, may
have played a significant role in bringing
the iceberg into the path of Titanic.
Because the evening of April 14, 1912 was
moonless the ship's lookouts did not spot
the iceberg until too late to avoid collision

The sinking of the ocean liner Titanic 100 years ago is perhaps the most famous--and most studied--disaster of the 20th century. Countless books and movies have examined in great detail the actions, choices and mistakes that led to the Titanic colliding with an iceberg the night of April 14, 1912, and sinking within hours, with approximately 1,500 people losing their lives in the icy waters of the North Atlantic.

One question, however, has often been overlooked: Where did the killer iceberg come from, and could the moon have helped set the stage for disaster?

Now, a team of astronomers from Texas State University-San Marcos has applied its unique brand of celestial sleuthing to the disaster to examine how a rare lunar event stacked the deck against the Titanic. Their results shed new light on the hazardous sea ice conditions the ship boldly steamed into that fateful night.

Texas State physics faculty members Donald Olson and Russell Doescher, along with Roger Sinnott, senior contributing editor at Sky & Telescope magazine, publish their findings in the April 2012 edition of Sky & Telescope, on newsstands now.

“Of course, the ultimate cause of the accident was that the ship struck an iceberg. The Titanic failed to slow down, even after having received several wireless messages warning of ice ahead,” Olson said. “They went full speed into a region with icebergs—that’s really what sank the ship, but the lunar connection may explain how an unusually large number of icebergs got into the path of the Titanic.”
