A new study from Western University posits proof to the possibility that an oncoming swarm of meteors may indeed pose an existential risk for Earth.
Cosmos is fraught with surprises for humanity. Predicting what will cause the destruction of the planet is difficult. Astronomers, watching the changes in the sky, concluded: in June, the Earth will face a danger that cannot be prevented.
This June the Earth is approaching a threatening meteor shower called Swarm Taurid . This phenomenon was 44 years old and did not occur so close to our planet.
A swarm of meteors heading towards Earth could have a catastrophic impact on our planet and its inhabitants, scientists have warned.
The Beta Taurids is a meteor shower that takes place every year between June 5 and July 18, when the Earth passes through a broad stream of debris left by Comet Encke.
It is less well known than some other meteor showers because it peaks after sunrise, making the “shooting stars” much harder to see. However, scientists believe that the cloud of debris may contain large space rocks that could pose a significant threat to life Earth.
Some have even suggested that one of these rocks could have been to blame for the most devastating meteor impact of modern times – the Tunguska Event of 1908, which flattened an area bigger than London and destroyed 80 million trees.
Luckily, no one was killed in the explosion, which occurred over the Podkamennaya Tunguska River in Russia. However, large areas of forest were obliterated, and the resulting shock waves threw people into the air over 40 miles away.
The Tunguska explosion is considered a one-in-1000-year event. But some researchers believe that another such phenomenon could occur much sooner.
The Earth will approach within 30 million kilometers (18.6 million miles) of the center of the Taurid swarm on June 28 – the closest such encounter since 1975.

Researchers from the Universities of New Mexico and Western Ontario warn we could be in for a similarly catastrophic event.
“If the Tunguska object was a member of a Beta Taurid stream, then the last week in June 2019 will be the next occasion with a high probability for Tunguska-like collisions or near misses,” the researchers wrote in a recent paper.

Meanwhile, researchers from Western Ontario University claim that the closeness of the Taurid swarm presents a unique opportunity to investigate its overall risk potential.
“There is strong meteoric and NEO evidence supporting the Taurid swarm and its potential existential risks but this summer brings a unique opportunity to observe and quantify these objects,” said David Clark, a Western graduate student.

The researchers added that, if the hypothesized might of the Taurid swarm is successfully proven, this also heightens the possibility of a cluster of large impacts over a short period of time.
Scientists stressed that the risk of a collision is still fairly low as – even in space terms – 18.6 million miles is a long way. However, “daylight fireballs” and “significant air-bursts” may be visible in the sky during the meteor shower’s peak activity, according to the researchers.
