Asteroid Impact craters in Australian outback.

Posting a few pictures of some spooky asteroids that hit Australian continent.

I am going to see one of these for myself and will post pictures of my own.

Gosses Bluff, Australia

Alice springs Central Australia

Wolfe Creek crater Western Australia

i dont no about these things.Can you plz explain.like it hit the surface we can see those marks but not that Asteroid.Why ?

Asteroid explodes and liquidates upon impacts or goes inside the earth's mantle.

The place in this picture you are looking at is about 300 million years old.

Can you please explain the science behind 'explosion' of Astroids? AFAIK, Asteroids are already at extremely high temperatures due to friction with earth's atmosphere. Upon explosion, they should shatter or embed into earth's surface.If they go inside earth's mantle, then we should be able to see the path that the asteroid followed into the mantle.

First i am not an expert on asteroids but what you and i have said are few theories , so far no exact answer has been given by the science about what exactly happens to asteroids upon impact.

It could vary because of the size , speed , chemical composition and the surface of the impact.

Remember we are looking at something that happened 300 million years ago , a lot changes in that time period i guess !

i dont believe these are asteriods craters, some thing hits the ground with that much force and didn't bounce or follow the inertial movement, leaves just a crater.. impossible.

About disintegration, if the force is that much that it disintegrates when it hits the surface then it should disintegrate below the surface leaving a big hole. Even a 100kg explosive TNT can leave deep craters.

Make yourself believe !

Outback asteroid strike caused huge explosion and left 80km shock zone, studies reveal | The Australian

It is estimated that these were formed 142.5 MILLION years ago. Erosion of top soil could have possibly covered up the inertial movement/hole caused by the asteroid.

I wonder if any exploration of the area has taken place to find out what's underneath the crater. We could find some interesting meteorites there.

Maybe we'll find some out of the periodic table Alien elements there, but the question is why no body excavates it to see whats inside?

I dunno, cost maybe. Imagine how deep they'd have to dig.

Anyways, there are plenty of fresh craters to explore. Why go after a 142 million years old one?

Check this one out.

Meteoroid kept in South Australia Museum.

^^^ now look at that thing it is a hard rock.And look at those marks on the earth surface So big... That means that big rock.where that thing disapear >?

It cant go inside coz look at the shape of those marks.

Asteroids have freakishly large amounts of energy. They can impact the earth at 20 to 50 km per second. The asteroid simply disintegrates, is vaporized in most cases to plasma. Some of the biggest blasts never even make it to the ground, they explode in the air with the force of a hydrogen bomb. The Tunguska meteor never impacted but devastated a wide area.

Here's a young crater (50,000 years), the famous meteor crater in Arizona:

Meteors explode, they don't bore holes like gophers.

Think of volcanos - when they blow up (like krakatoa) they don't leave a hole in the earth; overfly the crater, and look down, and you see it filled with rock.

Not at all, I just enjoy this sort of stuff.

When you start dealing with orbital velocities, weapons in orbit, that sort of thing, you don't need any sort of warhead or bomb. All you need is mass and velocity. And some of these meteors come in very fast indeed.
