Martin Bizzarro of the University of Copenhagen and his colleagues set out to determine the amount of iron in the early solar system. To do so, they measured nickel-60, a decay product of iron-60, in eight meteorites known to have formed at different times during the first 3 million years of the solar system. The meteorites that formed more than about a million years after the start of the solar system contain significantly more nickel-60 than do those that formed earlier, the team found.
In a neighborhood of young stars, only a supernova could have produced iron-60, the parent of that nickel. In contrast, all the meteorites, regardless of age, contain about the same proportion of aluminum. That element doesn't require a supernova source. These findings drastically revise a 30-year-old story line for the origin of the solar system, the researchers say in the May 25 Science. In that scenario, a supernova triggered the collapse of the ball of gas and dust that became the sun. But the new data suggest that the sun had already formed about a million years before the supernova explosion. The sun acquired its aluminum at birth or immediately afterward, Bizzarro says. The fact that all the meteorites had about the same amount of that element suggests that its source was a copious wind expelled by a massive star. The star had to be about 30 times as heavy as the sun, Bizzarro's team calculates. Within a million years, that behemoth -- which would have resided only about a light-year from the newborn sun -- went supernova, driving grains of iron-60 into the sun as well as into surrounding material that would eventually form planets.

The Sun: A Great Ball Of Iron?

Could the shock-wave have triggered planetary formation?
So our sun is a tenacious survivor who withstood a supernova and kept on trucking. I think that’s cool.
Possibly.
But it could also force the clearing of accretionary materials.
Dang, that was fast.

Here’s where I found the excerpt:
http://www.hotspotsz.com/Violent_Past__Young_sun_withstood_a_supernova_b__(Article-4816).html
... so now the search is on to find that went supernova so long ago - look for a nearby neutron star ....
So, the cosmos was without form, Big Bang created light, long after a local star went supernova for MORE light, and the resulting caused the solar system to form; fish were formed before man, man came about in God's spiritual image having the capacity to think and understand good and evil, and our human nature leads us to choose what is selfish rather than think first of others. Science again runs parallel to Scripture.
Clearing the accretionary materials would move us from living in the midst of a solar illuminated mist to clear daylight sun and clear dark nights...
And if such a blast was a contribution to LIFE BEARING planetary formation, it would also explain why we arn’t falling all over radio signals from other species...life may be rarer than we thought.
“It’s source was a copious wind expelled from a massive star”
So aluminum was made when Bette Middler farted. Who knew?
Yup. Similar to the old “passing star pulled enough matter from the sun to form planets being a rare event and that’s why it’s so quiet” explanation.
I think BIG moons are rare, and therefore no tides and therefore no high tidal pools with the variable concentrations of salts and organics sweeping trough favorable domains.
Or who knows? Maybe we are awash in signals propagated by other than electromagnetic waves?
is the iron in our blood from a supernova?
Or, the material out of which they were made could have arrived that way, being ex- of the supernova. There’s a link above to the “iron sun” topic and the underlying article (which isn’t linked at the topic, oddly) which suggests another scenario, which is that our Sun is itself the leftovers of the earlier star.
Takes a lickin’...
> Maybe we are awash in signals propagated by other than electromagnetic waves?
That was Thomas Gold’s take on it.
