MIT scientists create doomsday AI that will take over during end times

Posted by in categories: asteroid/comet impacts, existential risks, robotics/AI

A team of scientists at MIT have developed a computer program that will help humans decide how to best deal with the end of the world, so long as that comes in form of a catastrophic asteroid collision.

Experts say there as many as two or three new asteroids, sometimes called ‘Near Earth Objects,’ discovered every night.

7 Billion-Year-Old Stardust Is Oldest Material Found on Earth

Posted by in categories: asteroid/comet impacts, existential risks, space travel

Scientists recently identified the oldest material on Earth: stardust that’s 7 billion years old, tucked away in a massive, rocky meteorite that struck our planet half a century ago.

This ancient interstellar dust, made of presolar grains (dust grains that predate our sun), was belched into the universe by dying stars during the final stages of their lives. Some of that dust eventually hitched a ride to Earth on an asteroid that produced the Murchison meteorite, a massive, 220-lb. (100 kilograms) rock that fell on Sept. 28, 1969, near Murchison, Victoria, in Australia.

Hubble Gets Its Closest Look Yet at Approaching Interstellar Comet

NASA has released photos showcasing the best view of 2I/Borisov we’re ever going to get. The comet is the second interstellar visitor to our solar system since ‘Oumuamua shot through in 2017.

Pyramid-sized asteroid to zoom past Earth on Friday, as scientists warn one day a space rock may hit

Asteroids are coming?


The asteroid, dubbed 2019 WR3, has been directly observed some 74 times by NASA since it was spotted in the skies on November 27, so the space agency could calculate its size, speed and trajectory, and determine the threat level.

NASA now believes the space rock measures between 76 and 170 meters (249 and 557 feet) and is travelling at speeds of 27,036kph (16,799mph).

‘City-killer’: Asteroid the size of the Great Pyramid may hit Earth in 2022, says NASA

Posted by in categories: asteroid/comet impacts, existential risks, military

An asteroid estimated to be around the size of the Great Pyramid of Giza may hit the Earth on May 6, 2022, according to the National Aeronautics and Space Administration (NASA).

Despite the one in 3,800 odds — a measly 0.026% chance — of the asteroid smashing into the Earth, the worst-case scenario will surely be of a scene akin to the climax of an apocalypse movie, or even worse, as per NASA via The Daily Express on Nov. 16.

If the “city-killer” asteroid, labeled JF1, is to hit Earth, the impact would be equivalent to the detonation of 230 kilotons of TNT. That is 15 times stronger than the atomic bomb that hit Hiroshima in 1945, which destroyed the whole city with 15 kilotons of force.

Earth was on the other side of the galaxy when dinosaurs reigned

Posted by in categories: asteroid/comet impacts, existential risks

Apart from the asteroid that wiped out the dinosaurs 65 million years ago, there aren’t many connections between space and dinosaurs outside of the imagination. But that all changed when NASA research scientist Jessie Christiansen brought the two together in an animation on social media this month.

For the past decade, Christiansen has studied planet occurrence rates, or how often and what kinds of planets occur in the galaxy, while studying data from exoplanet hunters such as NASA’s Kepler, K2 and TESS missions.

During a stargazing party at the California Institute of Technology, Christiansen was explaining how young the stars were that they observed. The skywatchers were looking at the Pleiades, a bright young cluster of stars that are some of the youngest in our sky.

Fossil Trove Offers Clues to How Life Found a Way After Asteroid That Wiped Out Dinosaurs

Posted by in categories: asteroid/comet impacts, evolution, existential risks

On the outskirts of Colorado Springs, researchers have uncovered thousands of fossils showing how life on Earth revived in the aftermath of an asteroid impact 66 million years or so ago that killed most dinosaurs and other life on land and sea.

Taken together, the fossil trove documents an era when evolution, in essence, hit the reset button. While countless species vanished forever, some plants and animals rebounded relatively quickly in the first million years after the devastation, including the mammals ancestral to humankind, the scientists said in research published Thursday in Science.
