Remnants of a supernova were found in Antarctic snow. The space dust could be 20 million years old.

A star collapses when it dies, spewing out space dust in a giant cloud of elements that make for very beautiful Hubble Telescope photos. The “explosion,” called a supernova, results in either a black hole or an incredibly small, dense star that no longer generates heat.

A supernova also shoots space dust out in all directions that travels through the universe, occasionally coming into contact with other stars, planets — whatever happens to be in its path.

Earth has been around long enough to collect particles from exploding stars, even though it’s difficult to find the evidence. But sometime in the past 20 years, space dust from a supernova intersected with Earth and settled in Antarctica. The dust itself could be as old as 20 million years.

Scientists found a strange version of iron in relatively fresh Antarctic snow, according to a study published in the journal Physical Review Letters. Specifically, it was an isotope of iron, Fe-60, that astronomers know was present when our solar system formed. The discovery of the iron-laden dust could help scientists form a clearer timeline of our solar system.

2. We are stardust, we are golden

Woodstock

Well, I came upon a child of God
He was walking along the road
And I asked him, Tell me, where are you going
This he told me
Said, I'm going down to Yasgur's Farm
Gonna join in a rock and roll band
Got to get back to the land and set my soul free
We are stardust, we are golden
We are billion year old carbon
And we got to get ourselves back to the garden
Well, then can I roam beside you?
I have come to lose the smog,
And I feel myself a cog in somethin' turning
And maybe it's the time of year
Yes and maybe it's the time of man
And I don't know who I am
But life is for learning
We are stardust, we are golden
We are billion year old carbon
And we got to get ourselves back to the garden
We are stardust, we are golden
We are billion year old carbon
And we…
