Whether you saw the moon completely block the sun, were foiled by cloudy weather or weren't along the path of Monday's total solar eclipse, there are still more chances to catch a glimpse.

Total solar eclipses happen about every year or two or three, due to a precise alignment of the sun, moon and Earth.

After beholding the midday darkness of a total solar eclipse that raced across the continent, thousands of spectators in New England were stuck seeing only brake lights Monday night as highway traffic backed up for hours.

Crowds of motorists leaving remote northern New Hampshire in the late afternoon clogged local roads leading to Interstate 93, which they found also thronged by cars inching southward. By midnight, some drivers had traveled only 50 miles (80 km) in nine hours.

The New Hampshire Department of Transportation urged patience and said there were about 22,000 more vehicles visiting the tiny state compared to the same time last year. Heavy traffic was also reported in Vermont and Massachusetts.

A chilly, midday darkness fell across North America on Monday as a total solar eclipse raced across the continent, thrilling those lucky enough to behold the spectacle through clear skies.

Eclipse mania gripped all of Mexico, the U.S. and Canada, as the moon swept in front of the sun, blotting out daylight. Almost everyone in North America was guaranteed at least a partial eclipse, weather permitting.

It was the continent's biggest eclipse audience ever, with a couple hundred million people living in or near the shadow's path, plus scores of out-of-towners flocking in.

Clouds blanketed most of Texas as the total solar eclipse began its diagonal dash across land, starting along Mexico's mostly clear Pacific coast and aiming for Texas and 14 other U.S.
