Mystery of the gigantic Oort cloud from deep space explained

[FfFfFfFF 58,144]

Astronomers have calculated the first 100 million years of the history of the gigantic Oort cloud – a theoretical entity that contains 100 billion or so comet-like objects and forms a giant spherical shell around the sun and the rest of the solar system. NASA describes it as “a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger.”

The cloud is believed to be extremely far from the sun, many times more distant than the outer reaches of the Kuiper belt, the area of the solar system past the orbit of Neptune that contains comets, asteroids, and small icy space bodies as well as the dwarf planet Pluto.

“With our new calculations, we show that the Oort cloud arose from a kind of cosmic conspiracy,” said astronomer and simulation expert Simon Portegies Zwart from Leiden University, adding, “in which nearby stars, planets, and the Milky Way all play their part.

Each of the individual processes alone would not be able to explain the Oort cloud. You really need the interplay and the right choreography of all the processes together.”

So most solar systems dont have one? I always assumed it was a natural byproduct of star and solar system star fomation

 

Ive heard this buble helps shield us a little...

 

Yet another way our planet and solar system is blessed

It reminds me a little bit of the Chromatica symbol.
