Anomalous Metallic Object Discovered Inside a 4.5 Billion-Year-Old Meteorite

Anomalous Metallic Object Discovered Inside a 4.5 Billion-Year-Old Meteorite

Print

As meteorite dealers, my wife Linda and I have continued supplying meteorites and importing new stock throughout lockdown. On Friday, April 17th 2020, I received a parcel of meteorites I had ordered from a dependable regular source. These were twenty examples of a very well-known and popular common chondrite known as NWA 869. One of them was different and appeared to contain a metallic object inside.

For over twenty years we have been the owners of the UK’s only full-time meteorite dealership, Spacerocks UK. We both have university qualifications in astronomy and have lectured widely at many of the country’s most auspicious institutions. At any one moment we have several thousand meteorites of all types in our inventory. We are therefore completely familiar with their appearance.

The Very Ancient Origins of Meteorites

At this point, it’s worth giving a brief explanation about what meteorites are and where they come from. The solar system (the Sun, planets, asteroids and comets) condensed from a cloud of dust and gas known as the solar nebula around five billion years ago. The first solid objects were millimetric spheres called chondrules. These joined together over a few million years to form increasingly large chunks. Eventually, by collision, these accreted to form planetissimals and finally, around 4.5 billion years ago, the eight large planets and other, smaller bodies that make up the solar system.

Meteors, or shooting stars, are caused when fragments heat up as they enter the Earth’s atmosphere. If they survive to reach the Earth’s surface, they are known as meteorites. (lassedesignen / Adobe Stock)

The vast gaps between the orbits of the eight major planets are full of debris left over from these early days. Additionally, a region between Mars and Jupiter holds many thousands of smaller planetary objects known as asteroids. These occasionally collide (more so in the past), launching further rocky and metallic debris into the solar system.

If one of these fragments collides with the Earth on its passage around the Sun, it will heat up to over 6,000 degrees Celsius because of friction with the atmosphere. This is the cause of the familiar shooting stars, or meteors, we may see at night. If a chunk is large enough, it may survive and reach the surface of the Earth. This residual object is known as a meteorite.

Explaining the Types of Meteorite

There are, broadly speaking, three types of meteorite:

1) Chondrites: fragments of the original ancient stones that remain from the beginnings of the solar system. These often contain chondrules, the small spheres mentioned earlier. Chondrites are all around 4.5 billion years old.

2) Achondrites: stony material blasted off the surface of a planet, asteroid or satellite by the impact of another object. Achondrite meteorites have been proven to have originated on many bodies, including Mars, the Moon and asteroids such as Vesta.

3) Irons and stony irons are fragments of the cores of fully-formed small planets that were disrupted during collisions billions of years ago. As the first planets grew in size, heavy elements such as nickel and iron sank to their centers to form metallic cores, like that of the Earth.

Generally speaking, meteorites are named after the place where they fell or were found. That’s why the iron meteorite that made the Arizona Meteor Crater is called Canyon Diablo and that which exploded over Russia in 1947 is known as Sikhote-Alin.

The NWA 869 Meteorite in Question

The meteorite we are discussing here, NWA 869, comes from a large strewn field which was the 869 th such to be discovered in North West Africa: hence its name. Why 869 is so prized by collectors is that most of meteorites from this field are small, complete examples, rather than fragments of larger bodies that exploded as they passed through the atmosphere (see photos).

The majority have an attractive blue-grey fusion crust (melted surfaced) and their shape reflects their attitude as they streaked downwards. This is known as ‘orientation’: a bit like the way spacecraft enter the atmosphere heat-shield first. OK, that’s the technical stuff out of the way!

When I was processing the parcel of newly-arrived 869s, I suddenly noticed a metallic glint from one of them. This isn’t unusual: all chondrites contain nickel-iron and some (see photo) display quite obvious metallic flecks. This was different. In this case, the shiny region could be seen to be a small cylindrical feature around 6 mm (0.2 in) in diameter.

This metallic area was protruding at an angle from a region of glassy fusion crust, which, in places, could be seen to flow away from the object. Another interesting feature is that the cylinder had a small impact crater on its surface, something not uncommonly seen on iron meteorites or, indeed, spacecraft on their return from orbit.

The meteorite and its strange inclusion have been examined both microscopically and spectroscopically by a contact at the University of East Anglia. The preliminary results indicate that the silver cylinder is not composed of any of the usual accessory minerals found in meteorites. Further examination is scheduled.

I have no doubt at all that the object embedded in the NWA 869 meteorite was in place as the stone entered the Earth’s atmosphere some time in the past. Since the meteorite itself was formed several hundred millions of years before the planets, it begs the questions: who made it, and where did it originate before becoming part of the solar nebula? A very real possibility might be that the cylinder originated on a planet orbiting a Population 2 star that exploded as a nova several billion years before our solar system formed.

What Could This Discovery Mean?

The oldest stars in the universe are, counterintuitively, called Population 3 stars. The “nuclear furnaces” at the heart of these were the origin of some of the elements “heavier” than hydrogen. As these ancient stars ran out of hydrogen, the larger ones would have shrunk, then exploded, releasing gas, dust and some of these heavier elements into the universe. It was this material that condensed to form Population 2 stars ten to fifteen billion years ago. The larger examples of these also underwent cataclysmic supernovae, generating regions of star formation where Population 1 stars like our Sun – and their associated planets – condensed.

It is now known that planets are very common. So far astronomers have discovered over 4,000! It is probably the case that most Pop 1 stars have planetary systems. Since the oldest of these stars were formed ten billion years ago – twice as long ago as the Sun – it would seem highly likely that life and ultimately civilizations evolved upon those in suitable locations.

Any that ended their lives as supernovae will have scattered all kinds of stellar, planetary and – possibly – archaeological debris into its galaxy. Either we are alone – unique – in the cosmos, or life occurs wherever there is the slightest possibility of it: in which case, we should expect to find alien artifacts within ancient meteorites.

Silicon, Oxygen, Calcium and Magnesium. This is definitly not the spectrum of the metal itself. But this would perfectly fit to a spectrum of crust atop of the metal. This metal is just a common iron nodule, which can be found in many chondrites. The best known similar iron nodules are the frankonia irons.

Thanks for the article ... It does look like an anomalous piece of metal !
There is another theory of meterorite origins that might explain the metalic inclusion.  It’s a bit out in left field but, as I said, interesting.   Dave Talbott is a mythologist who has come up with a theory of interplanetary interactions/collisions based on his interpretations of ancient petroglyphs.  It’s a different approach but may have some validity in regard to your find.
Talbott’s theory can be found at:  thunderbolts.info

More analysis needed. Could it be possible this chondrule 4.5 billion picked up/joined with older heavy iron metallic elements created in the population 2 and 3 stars which are older.

Maybe there was a older star with some type of geologic process of making certain elements we do not know about yet.

It always amazes me just how strongly my metal detector reacts to even the smallest of meteorites.

In 2003 I had the privilege of spending two weeks metal detecting the Sou’East portion of England.

out of my many finds during the trip my two favorite were a half inch sliver of a meteorite with what appears to be green dust Inside very small impact crater that you need jewelers loop to see and best find being a bronze, tin coated rope swirl ring .

The archaeologists on site with the British Museum declared it to be a Viking ring from the eighth century.

Hi!
Thanks for your comment: as you can see from the spectrographic anaysis, the object has a composition completely unlike a bullet...
