June 30th is the day which is celebrated as Meteor Day also known as Meteor Watch Day!
The word “meteor” stands for the vibrant visible streak of light generated by fallen debris from space—"meteoroids." These are also termed as “shooting stars” or “falling stars.”
Meteors are space particles or dust and ice that come in the contact of earth's atmosphere. As they enter the atmosphere layer at great speed, they burn up, generating light as they streak across the night sky.
One of the best-witnessed meteor showers is the Perseid, which has been observed for almost 2000 years! Every year, viewers in the Northern Hemisphere celebrate Meteor Day by viewing a spectacular showing in the sky at night time. From the middle of July to mid-August, dozens of meteors are seen across the darkened sky.
An explosion illuminated the sky on June 30, 1908, over Siberia, which is probably the origin of Meteor Day. Seen from hundreds of miles, the incident is attributed to a meteor and is termed as the "Siberian Explosion." The incident is also considered as the "Tunguska event," as the meteor is believed to have busted over the Tunguska River.
The estimated strength is 1,000 times greater than the atomic bomb dropped over Hiroshima. The Tunguska incident leveled entire trees over 40 kilometers away and trembled the ground in a tremendous earthquake as stated by NASA.
Almost 3000 tons of substance falls on earth every day from outer space. Most of it gets destroyed in Earth’s atmosphere in the form of a meteor or shooting star. But a small quantity of it which reaches earth is called a meteorite. If a meteorite is huge, its impact generates a crater.
A very huge meteorite melts the rock in the crater because of the impact. If some of this melt is tossed from the crater into space it stiffens into a glass called a tektite and it again comes back to earth. This type of tektite was formed in Thailand nearly 730,000 years ago.
A new believe on the origin of tektites indicates that they were part of a ring just like the planet Saturn which has fallen back to Earth thousands of years ago. This new theory also offers some reasonable explanations for anomalous facts pertaining to tektites that don’t go well with mostly believed facts of impact and molten ejecta coming back to Earth.
Every year to commemorate these event and history of meteor “Meteor Day” is celebrated and most people keep their eyes glued to the sky to view some falling stars.
