There’s big money to be made in asteroid mining

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

If humans were ever able to get their hands on just one asteroid, it would be a game-changer.

That’s because the value of many asteroids are measured in the quintillions of dollars, which makes the market for Earth’s annual production of raw metals – about $660 billion per year – look paltry in comparison.

The reality is that the Earth’s crust is saddled with uneconomic materials, while certain types of asteroids are almost pure metal. X-type asteroids, for example, are thought to be the remnants of large asteroids that were pulverized in collisions in which their dense, metallic cores got separated from the mantle.

Asteroids could threaten Earth, scientists say

Captain Obvious has OBVIOUSLY taken over NASA, I’m afraid.

Space rocks are a bigger threat than people realize, scientists say. An organization is trying to bring awarness to the dangerous of asteroids.

Evidence of ancient giant asteroid discovered in Australia

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

ACTON, Australia, May 16 (UPI) — Researchers in Australia recently found a collection of spherules, evidence of a massive asteroid that struck Earth as it was still forming.

Spherules are tiny glass beads formed from material vaporized in the intense heat of an asteroid impact. They were found in northwestern Australia by a team of geologists led by Andrew Glikson of the Australian National University.

The glass beads were found scattered among ancient ocean sediments dated to the middle of the Archean Eon — 3.46 billion years ago. The spread of the spherules deposit suggests the impact would have left a crater between 12 and 18 miles in diameter.

If Something Is Going To Destroy Humanity, It’s Going To Be One Of These Catastrophes

Pandemics, asteroids, nuclear war, and sudden, destructive climate change are all unlikely—but not so unlikely that we shouldn’t be planning for them.

Jeff Bezos wants to open the way for millions to live, work in space

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

COLORADO SPRINGS — Jeff Bezos, founder of Amazon.com, could not be more clear about what he believes is mankind’s future.

“I want millions of people living and working in space. I want us to be a space-faring civilization,” Bezos told a packed audience at the Space Symposium on Tuesday in Colorado Springs.

“My motivation is, I don’t want Plan B to be, ‘Good news, Earth got destroyed by a big comet but we live on Mars.’ I think we need to explore and utilize space in order to save the Earth,” he said, referring to the need to shift industrial manufacturing to space to limit the impact on Earth’s resources.

Newly discovered planet could destroy Earth any day now

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

Look up the definition of irresponsible journalism and you’ll probably find a link to THIS article.


A mysterious planet that wiped out life on Earth millions of years ago could do it again, according to a top space scientist.

And some believe the apocalyptic event could happen as early as this month.

Could ‘Planet X’ Cause Comet Catastrophes on Earth?

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

As astronomers track down more clues as to the existence of a large world orbiting the sun in the outer fringes of the solar system, a classic planetary purveyor of doom has been resurrected as a possible trigger behind mass extinctions on Earth.

Yes, I’m talking about “Planet X.” And yes, there’s going to be hype.

Something Just Slammed Into Jupiter

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

Astronomers have captured video evidence of a collision between Jupiter and a small celestial object, likely a comet or asteroid. Though it looks like a small blip of light, the resulting explosion was unusually powerful.

As Phil Plait of Bad Astronomy reports, the collision occurred on March 17, but confirmation of the event only emerged this week. An amateur Austrian astronomer used a 20-centimeter telescope to chronicle the unexpected event, but it could’ve been some kind of visual artifact.

Flyby Comet Was WAY Bigger Than Thought

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

Oh, joy. I hope it doesn’t take an actual catastrophe before the world comes together to get all of our eggs out of this one basket.


Comet P/2016 BA14 was initially thought to be a cosmic lightweight, but as it flew past Earth on March 22, NASA pinged it with radar to reveal just what a heavyweight it really is.

100-foot asteroid to zoom past Earth in two weeks; no chance of collision, scientists say

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

An article for the “Dooms Day” fans.


An asteroid roughly 100 feet long and moving at more than 34,000 mph is scheduled to make a close pass by Earth in two weeks.

But don’t worry, scientists say. It has no chance of hitting us, and may instead help draw public attention to growing efforts at tracking the thousands of asteroids zooming around space that could one day wipe out a city — or worse — if they ever hit our planet.
