HOW WAS OUR SOLAR SYSTEM CREATED??

Blog#396

Saturday, April 27th, 2024.

Welcome back,

Here we are, 4.5 billion years into the lifetime of our sun, with an array of planets and smaller objects orbiting around it. How did all the planets form, and why did they end up in the orbits that they did?

The formation of the solar system is a challenging puzzle for modern astronomy and a terrific tale of extreme forces operating over immense timescales. Let's dig in.

I can't help but start with: In the beginning, there was nothing. But it wasn't quite nothing. All stars form from the collapse of nebulae, which are loose clouds of gas and dust, and our sun — and solar system — are no different. Astronomers call it the "pre-solar nebula" and of course it isn't around today, but we've seen enough solar systems forming throughout the galaxy to get the general picture.

But a nebula on its own won't collapse into a solar system without something to set it in motion. In our case, we can thank a nearby supernova explosion, whose shockwave ripped through the pre-solar nebula, causing it to begin its contraction.

We can tell that such a supernova went off nearby, because supernovae release great quantities of certain radioactive elements — elements that aren't normally found inside nebulae – but which we can see in our solar system today.

Once underway, the transition from nebula to solar system was irreversible. Over the course of millions of years, the nebula contracted and cooled, eventually reaching the point where a proto-sun was surrounded by a thin, rapidly rotating disk of gas and dust.

And then the fun began.

Four and a half billion years ago, our sun wasn't quite the shining star that it is today. It was compact and very, very hot, but it hadn't reached the critical densities and temperatures needed to sustain nuclear fusion in its core.

But while it was still in this embryonic stage, the planets began their slow waltzing formation.

I feel like nobody on Tumblr knows that the international space station is being discontinued.

Did you know that? In less than a decade it will be gone

Sputnik 2, launched on November 3, 1957, carried the dog Laika, the first living creature to be shot into space and orbit Earth. Laika was a stray dog found on the streets of Moscow. There were no plans to return her to Earth, and she lived only a few hours in orbit. …
