A team of astronomers from the Texas State University have discovered that a rare lunar event had actually caused the Titanic disaster.

Astronomers discovered that an unusually close approach by the moon on 4 January, 1912, might have caused abnormally high tides, when the moon's perigee was at its closest in 1,400 years.

"It was the closest approach of the moon to the Earth in more than 1,400 years, and this configuration maximized the moon's tide-raising forces on Earth's oceans. That's remarkable," said Donald Olson, professor at the Texas State University in a statement.

Another rare coincidence which occurred a day before the disaster was the Earth's closest approach to the Sun.

Astronomers believe that this rare combination of the moon and Sun's closest approach could have also been the major reason behind the disaster.

According to the astronomers, icebergs normally remain in place and cannot resume moving southward until they've melted enough to refloat or a high enough tide frees them.

But the unusually high tide on 4 January, 1912 would have been a major cause for those icebergs to move them back into the southbound ocean currents, where they collided with the Titanic.

The Titanic collided with an iceberg on the night of 14 April, 1912, and it sunk within hours.

More than 1,500 people lost their lives in the icy waters of the North Atlantic.
