New Delhi: On Monday evening skygazers across the globe have been treated to one of the rarest celestial events- the incredible sight of Mercury passing in front of the Sun - that occurs only about 13 times a century.
Mercury - the solar system's smallest planet - came between Earth and the sun that lasted from 7:12 a.m. EDT (4:42 p.m, India time) until 2:40 p.m. EDT (12:10 a.m, Tuesday).
The event - which astronomers call a transit of Mercury, is not visible to naked eye. The rare solar transit that that occurs just 13 times a century can be watched using magnification tools - binocular or telescopes. Looking directly at the Sun can cause serious eye damage and even blindness.
For those who can't see the rare transit, there are plenty of ways to spot the event online. People can watch the transit webcast live at at Slooh's website.
Skywatchers can also catch the spectacular astronomical show live via live streams from the European Space Agency and NASA's Goddard Space Flight Center in Maryland.
