Total Solar Eclipse's are rare. During a total solar eclipse the Moon completely covers the Sun, as seen from Earth. The phenomenon can be observed when the Moon moves between the Earth and the Sun, and the three celestial bodies form a straight line: Earth - Moon - Sun.
Eclipse's attract a great deal of interest from far and wide, so it is always best to book travel arrangements early - hotels fill up fast as travellers come from all over the globe to the countries deemed to be the best for witnessing this once in a lifetime phenomenon.
According to NASA, one of the best places to see the March 2016 eclipse is Indonesia. Read NASA's guide here.
Totality of a solar eclipse can last up to 7 minutes and 31 seconds, but these eclipses are very rare. The next instance of a similarly long totality is predicted to occur in 2150, when the Sun is expected to be completely obscured for 7 minutes and 14 seconds - longer than during any total solar eclipse since the 9th century. Even more rare is the simultaneous occurrence of a solar eclipse and the transit of a planet. The next time Venus is predicted to move in front of the Sun during a solar eclipse is on April 5 of the year 15232.
