This prediction of an asteroid impact on Earth will give you goose bumps

Scientists believe a 40-million-ton asteroid set to fly close to Earth in 12 years may end up colliding with our planet on a future pass.


The Apophis asteroid will pass within 18,600 miles of Earth on April 13, 2029, which is ridiculously close by space distance standards. Scientists expect the near-miss to disrupt the asteroid's orbit, making its future path unpredictable.

This means there's a small chance Apophis could hit Earth on a future pass. Apophis will pass by the Earth again in 2036.

"You can find a full table of objects for which the impact probability is not mathematically zero," Dr. Richard P. Binzel, a planetary science professor at Massachusetts Institute of Technology who's involved in research on Apophis, told The Daily Caller News Foundation. "The table includes Apophis with a probability of 8.9e-6 (less than one chance in 100,000)."

If Apophis did strike Earth, it could create a crater about 1.25 miles across and almost 1,700 feet deep. Such an impact could be devastating, as on average an asteroid this size can be expected to impact Earth about every 80,000 years.  It could annihilate a city if it were to directly land on an urban area. The blast would equal 880 million tons of TNT or 65,000 times the power of the atomic bomb dropped on Hiroshima.

"We can rule out a collision at the next closest approach with the Earth, but then the orbit will change in a way that is not fully predictable just now, so we cannot predict the behavior on a longer timescale," Alberto Cellino of the Observatory of Turin in Italy, told Astrowatch.net.

MIT announced last month that professors and students are designing a space probe mission to observe the asteroid "99942 Apophis" as it passes Earth in 2029. MIT or NASA would have to launch the probe before August of 2026 due to the way orbital mechanics work.

The MIT probe could teach scientists more about the construction of asteroids, providing valuable information about the formation of our solar system. What scientists learn from the Apophis encounter could make it easier to mount a planetary defense in the event an asteroid was ever found to be on an impact course.

In December 2004, initial observations of Apophis indicated it had a 2.7 percent chance of striking Earth in 2029 or exactly seven years later. This has since been revised downward considerably.

Smaller asteroids are much harder to detect and there's little that could be done to stop a small space rock on course for Earth without early warning. Typically, these rocks are discovered just days or hours before they pass by Earth.

There's not a shortage of space rocks that put our planet at risk either. Global asteroid detection programs found more than 16,314 near-Earth objects of all sizes — 816 new near-Earth objects were identified so far this year alone, according to International Astronomical Union's Minor Planets Center.

China and the US could end up in a war – here's what would happen

It's unlikely that the U.S.-China trade dispute is going to escalate to a full-scale war any time soon — but it's not impossible. Neither side is inclined to go to war with the other, but a war of that scale is what both plan to fight. All it would take is one bungled crisis, one itchy trigger finger, one malfunctioning automated defense system and the entire region could become a war zone.

This is how American pilots used drop tanks as bombs during WWII

If you pay attention, you might sometimes see long, cigar-shaped pods firmly attached to the undersides of classic fighter and attack aircraft, sometimes with unit markings on them.

Known as "drop tanks," these simple devices extend the range of the aircraft they're hooked up to by carrying extra usable fuel. Back during World War II, however, attack pilots found a secondary use for drop tanks as improvised bombs, used to bombard enemy ground positions.
