Discovery of asteroids: A collision of asteroid 'bigger than dinosaur killer' sparks new life | Science | News



The study was published in Science Advances, led by Birger Schmidt at the University of Lund in Sweden. The work suggests that a distant asteroid collision produced enough dust to cause an ice age on Earth, about 470 million years ago. During this period, known as the GOBE (the major Ordovician biodiversity event), there has been a significant increase in biodiversity, especially in marine life.

The asteroid, which the study claims has collided with another asteroid outside the orbit of Mars, may have produced enough dust to cover the Earth and subsequently dramatically cool the planet.

Birger Schmidt, who led the study, told The Observer: "We know of a 10-kilometer asteroid that crashed on Earth 67 million years ago and killed dinosaurs, but this event was very different.

"This happened about 470 million years ago, when an asteroid 3,000 times the size of a dinosaur killer was destroyed during a collision with another asteroid beyond the orbit of Mars.

"He filled the solar system with dust and caused a significant blackout of sunlight falling on Earth. "

She told Science magazine: "This is not necessarily the answer to every question we have about Gobe, but it certainly connects many observations."

] Philip Heck, author of the study, also said: "We have shown that what happens in the solar system can have a big impact on Earth. Extraterrestrial events are not always destructive. Many people think of meteorites as just dinosaur killers, but we have found the opposite.

To boost the mission, the space agency is giving $ 1

9 million to UCF – though it is believed that hunting for NEOs will be difficult. [19659003] NASA is aiming to find 90 percent of the world's asteroids that are equal to or greater than 460 feet (140 meters) by 2020.

NASA Administrator Jim Bridenstein warned the chances of impact are greater than humans aware.

The NASA administrator said, "We have to make sure that people understand that this is not Hollywood, it is not about movies.

" This is about protection, ultimately, of the only planet we know at the moment. the life of the hosts – and this is planet Earth. "
