A lot of interesting incidents happen every day in this modern world. Human experimentation has come a long way and the technological revolution played a massive role in that. However, nature continues to prove its supremacy by providing the rarest yet the most beautiful events on Earth. They don’t only amaze you due to the beauty but the story behind them is even more compelling. Some of them are:

Volcanic Lightning

There is no conclusive verdict on why they occur but a popular theory that is rated highly by the scientists is that positively charged debris is sent to the atmosphere during a volcanic eruption. This leads to a chemical reaction between the debris and the negatively charged particles already present in the atmosphere. Resultantly, massive bolts are produced. Both ice crystals and ash clouds are considered responsible for this amazing yet terrifying sight.

Halley’s Comet

It is a comet that takes 75 years to orbit around the Sun. The name comes from the astronomer who discovered it for the first time, Edmund Halley. It is lightened by the reflected light of Sun. It can be seen from different locations of the Earth. The most recent appearance of this comet was in 1986 and you can manage to have a look at it again in 2061.

Donuts of Snow

It is an extremely rare sight as perfect conditions are needed for their formation. If a huge ball of snow falls and gathers more snow on its way down, it rolls down in a way that is quite similar to a human’s fall. The central parts of this ball collapse giving it a shape of a donut. It is an aesthetically pleasing sight to see a snow donut which is 26 inches high.

Planetary Alignment

These events are very rare in our solar system where multiple planets are aligned. Straight as well as triangular alignments have been reported till now. Different planets have become part of these amazing occasions. Venus, Mars, Jupiter, Saturn, and Mercury were involved in an alignment in 2000. All these planets are expected to align themselves with the Moon of our planet in 2040. Venus, Mercury, and Jupiter combined again in 2011 to give a triangular alignment.

Fire Rainbows

The name might seem a bit horrifying but there is nothing to worry about as the reality is quite beautiful. These large halos of refracted light are formed when the sun is at least 58o above the horizon. The presence of cirrus clouds is equally important as the plate-shaped crystal of ice in these clouds are essential for the development of this outstanding sight. They are associated with fire because only some parts of the clouds are visible from Earth and it gives an impression as if a fire is lit among clouds.

Blue Moon

The history behind this term holds great significance as it has nothing to do with astronomy or any other scientific concept. In 1883, a volcanic explosion in Indonesia spread dense ash everywhere in the atmosphere. Following this incident, the moon appeared blue and it was a second full moon that night. This gave birth to this phenomenon. This effect can be seen if certain coloring particles are present in the atmosphere. It is quite possible to get two full moons in a month as almost all the months have 30 days and there is a gap of 29 days between two full moons. Having said that, it happens very rarely.

Auroras

These are simply mesmerizing lights seen in the skies of the regions that are closer to the poles. They are produced when charged particles of Sun’s atmosphere collide with the gaseous particles of our planet. The best areas to experience these polar lights are Northwest Territories, Alaska, Greenland, Iceland, Yukon, Nunavut, Siberia, and Norway. Places, where levels of pollution are low, have better visibility for these auroras.

Total Solar Eclipse

Solar eclipses are seen quite commonly around the year. The event that is seen once in many years is the Total Solar Eclipse. It happens when Moon covers the Sun completely. The scientific name of it is ‘umbra’. In this short interval of time, the disc-like Sun hides behind the moon’s crescent. It was recorded in November 2012 and scientists have estimated that it won’t happen again for 138 years.
