Study author Jiří Borovička states, “A systematic search for asteroids within the newly identified branch will be needed to find the size-frequency distribution of large bodies within the branch.” Furthermore she adds, “The impact risk increases during the encounters of the Earth with the branch.”, She describes the risk of Earth being hit by a large asteroid during one of these encounters as a “lottery”—or “to be hit by a bullet or not.”. Now a team from Western University in London, Ont., are calling for closer examination of the Taurid meteor swarm. At least one meteor observed in 2015 had an estimated size of about a meter (3.28 feet). Meteor showers are visible when tiny bits of cosmic debris enter Earth’s atmosphere and burn up in the sky while entering the Earth’s atmosphere. As an amateur astronomer, Nicole can be found looking up at the night sky appreciating the marvels of our universe. Over the past few decades, astronomers have wondered if a nearby swarm of material — one through which Earth crosses — may hold rocks that could pose a danger to humans. 1. Near Earth Objects (NEOs), like comets, meteors, and asteroids, could wreak continental devastation on our planet should they collide with Earth. And hence a new meteoroid stream has been found. This will be the closest our planet has been to the stream since 1975. Some meteoroid streams produce only a few visible meteors, but sometimes Earth passes by a denser swarm of particles, thus causing a more impressive or active meteor shower. It's suspected of having relatively large objects, from 100 metres to one kilometre … and they're clustered, so they're not hitting at random times," said the paper's lead author, David Clark. This very summer, for instance, Earth will be within 18,641,135 miles of the Taurid stream’s center. The Taurids meteor shower peaks every October and November, producing a relatively small display of shooting stars as the planet passes through its stream. (That's us.) And if it is, it could mean that Earth is likely to experience a large space rock exploding in the atmosphere more often than once in a thousand years, as is the current belief. A Halloween season 'Taurid meteor swarm' on tap for 2015? Finding these large objects will be a challenge, as they will be quite dim. Some of the debris from this event is believed to have collided with the Earth, and has been connected with at least one catastrophic event in Earth’s history. According to Western Meteor Physics Group data analysis, the Earth will approach within 30,000,000 km of the center of the Taurid swarm this summer, the closest such encounter since 1975. Then something else got astronomers’ attention. Launching the event in 2014, astrophysicist Brian May said, "The more we learn about asteroid impacts, the clearer it becomes that the human race has been living on borrowed time.". Is it possible that larger objects in the newly found Taurid meteor stream might also encounter Earth? The content is provided for information purposes only. Study author Jiří Borovička states, “A systematic search for asteroids within the newly identified branch will be needed to find the size-frequency distribution of large bodies within the branch.” Furthermore she … A new study from Western University posits proof to the possibility that an oncoming swarm of meteors—likened to the Loch Ness Monster and Bigfoot by some extraterrestrial experts—may indeed pose an existential risk for Earth and its inhabitants. To encourage thoughtful and respectful conversations, first and last names will appear with each submission to CBC/Radio-Canada's online communities (except in children and youth-oriented communities). However, now that we know it exists, the researchers say we need to carry out further studies to better understand "this real source of potentially hazardous objects. However, these intervals might only come once every century, said Brown. Apart from any fair dealing for the purpose of private study or research, no By 2050, $1 trillion. But the rocks that could be lurking in the Taurids would be very different. The Tunguska event was believed by scientists to take place perhaps every 1,000 years, but a new study from Western Ontario University claims otherwise.
