Stanislav Petrov was a Soviet lieutenant colonel who is credited with saving the world from nuclear war on September 26, 1983. On that night, Petrov was the duty officer at the Serpukhov-15 bunker, which housed the command center for the Soviet Union's early warning satellite system. At 00: 40 UTC, the system reported that a missile had been launched from the United States. Petrov dismissed the report as a false alarm, but just three minutes later, the system reported that four more missiles had been launched. Petrov was faced with a difficult decision. If he reported the incoming missiles to his superiors, they would likely order a retaliatory nuclear strike against the United States.

The Soviet Union had recently shot down a Korean Air Lines passenger jet, and Petrov knew that this co...

Solar Eclipse A solar eclipse occurs when the Moon passes between the Earth and the Sun, casting its shadow on the Earth. This can cause the Sun to appear partially or totally obscured, depending on the alignment of the three celestial bodies. Types of Solar Eclipses There are four main types of solar eclipses: Total solar eclipse:  This occurs when the Moon completely blocks the Sun's disk. This is the most dramatic type of solar eclipse, and it can only be seen from a narrow path on Earth. Partial solar eclipse:  This occurs when the Moon only partially blocks the Sun's disk. A partial solar eclipse can be seen from a much wider area than a total solar eclipse. Annular solar eclipse:  This occurs when the Moon is too small to completely block the Sun's disk. This leaves a ring of sunlight visible around the Moon. Hybrid solar eclipse:  This is a rare type of solar eclipse that starts as an annular eclipse and ends as a total eclipse, or vic...
