EARTH is bombarded by a series of potentially apocalyptic asteroid attacks, as revealed by NASA data. Space is a dangerous place with deadly radiation doses, minus temperatures and unimaginable pressures. And even the Earth is not completely immune to extraterrestrial dangers, because our planet is exceptionally rocked by space rock.
Now, the data released by the NASA have revealed that the asteroid impact rate actually increases.

Although asteroid attacks are extremely rare, it is possible to pulverize the planet.
Just a geological wink Most of the earth's life, including dinosaurs, was extinct 66 million years ago.
The cause of this mass extinction ̵

Asteroid Attack: Space Rock Beats Our Planet Three Times More Frequently
 Apollo 11: Some of the research data used Apollo samples
. Researchers now believe that asteroids fall into the ground almost three times as fast as when dinosaurs roamed the world.
The scientists involved in the study exclusively explained how they calculated the collision increase.
Dr. Gernon, a professor of earth science at Southampton University, said, "The Moon is our nearest neighbor, so it's hit by the same asteroid population
" For this reason, it provides a clean beating effect because, unlike Earth, it does affected by erosion and plate tectonics, which interferes with impact craters.

"We were able to use the samples collected by NASA astronauts during the Apollo missions and some of the Crater. 19659006] "And we were able to use this dataset to calibrate a new crater dating method based on measurements taken on NASA's Lunar Reconnaissance Orbiter. "
The idea is that the collision blow produces many large rocks and these rocks break billions of years after being bombarded by many micrometeorites.
They also heat up during the day and cool off at night, claiming the rock and dissecting it.

Asteroid strikes: The asteroid belt is located between Mars and Jupiter
This allowed researchers to discover a link between rock abundance and age.
Dr. Gernon describes how the asteroid belt of our solar system is the most likely explanation for the threefold impact that Earth and shaken her moon.
He said, " In the asteroid belt, somewhere between Mars and Jupiter, some of these space rocks sometimes collide.
"Breaking up one or more asteroids may produce many fragments that can be moved to Earth over time.

"Over time, these stones get bomb The sunlight is leading to the fact that there is a process that re-emits this energy and essentially gives these fragments a tiny nudge that can then send them on a collision path towards Earth.
"It's a bit of a rising tide; You have a lot of material from the asteroid belt at one point. "
Dr. However, Gernon is keen to emphasize how rare apocalyptic impacts of the earth are, even when the probability is doubled or even tripled. People need not worry about this increased flow.
"We say that large asteroid impacts – more than 1 km in diameter – have decreased to about 1-2 every three to five million years, 90 million years ago, every million years. "

Asteroid Attack: The NASA has a special program for monitoring objects near the Earth
And although this represents an increase, asteroid attacks are random events, so does not mean that the Earth is overdue for another collision is.
In addition, NASA has a special program for monitoring near-earth objects (NEOs).
All of the space garbage is potentially being dangerously monitored for Earth, and there is an American Defense Division working with NASA to keep an eye on the impact risk.
Dr. Gernon, of the University of Southampton, believes we can learn a lot about the Earth by looking at the moon.
He said, "We can all see these pockmarks on the moon, and it's just fascinating to look at them and believe that we can use the data we have collected to understand how our planet has been affected by these events Time. "
