-- A team of scientists hauled 500 kilograms of fresh snow back from Antarctica, melted it, and sifted through the particles that remained. Their analysis yielded a surprise:
Outer space objects ranging from dust to meteors regularly fall to Earth, but they are generally made of the same materials as our planet, since everything in the solar system, including the sun itself, assembled from the same building blocks billions of years ago. Because iron-60 is not among those common materials, it must have arrived from somewhere beyond the solar system.
What was left was hundreds of times more of the iron isotope than they expected."That’s really overwhelming," Koll said. Stars fling out a variety of tiny particles during their lifetimes, in addition to all the light and heat. But when the stars are younger, they’re generally throwing out lighter metals, like carbon and oxygen. Aging, massive stars and a certain type of supernova explosions, having spent many millennia fusing big nuclei into even bigger ones, can spew out particles of heavier metals, including iron-60 and its stable cousin, iron-56.
according to Nasa it was small amounts bury in the snow.
BritonandDane That was me, I left it there. Bit sloppy, sorry!
Keep digging....👽👽

Ziggy?! Any evidence of The Spiders From Mars?

'Called iron-60, it has 4 more neutrons than Earth's most common form of the element. But the iron-60 in the crust likely settled on the Earth’s surface millions of years ago, as opposed to what was found in fresh snow in Antarctica that had accumulated over the past 2 decades'
We are going to start finding lots of stuff as the world is melting stardust
Man your shit runs deep. Let's discuss the Antarctic Treaty signed by almost every country ..1 year after Nazi NASA was formed..preventing anyone from traveling there. ...why? No, it's not to 'protect the land'... What is being hidden? NASAlies

That has convinced me: snow comes from aliens. But why do aliens like Buffalo and Denver better than, say, Cincinnati or Baltimore?
Fallout?

Trumpium?
It sounds magical
Vibranium? 😉 CaptainAmerica

Star dust? Really? Dust from an actual star?
I found some in my driveway last week ! What’s the big deal !!
We all are Star dust
It's as if there is an inter-relationship between planet earth and the rest of the universe. Fancy that.
Anyone who follows neiltyson knows we’re all made of starstuff so this isn’t surprising
Iron is made in exploding stars.
It's iron 60.
Well , that's a good source of iron if the snow can really produce it largely. Looks like preservation will be needed to keep the snow in good shape.

Thought Antarctica was sunny and 70. Have to turn the tv off
Meteors can bring!
