The Deadliest Life-Giver

If you ask 10 people how and why we're alive here, on this rock that was once dust circling a very young star, you'd get 10 different answers. One fact cannot be disputed: Life should NOT be able to thrive here. We're too close to a star, middle-aged but very potent, throwing off super-solar storms of radiation continually. Right now, hundreds of billions of cosmic rays are penetrating your thumbnail. Our bodies are exposed to toxic cosmic rays from our star, the sun, all day, all night, all the time, all these years we've been in existence. Not just us: ALL LIFE.

So: Life shouldn't exist here in Earth, it's bombarded by radiation. Look at these sun-spots, they are causal to solar flares and our weather. Dangerous emissions of radiation. It makes you wonder, once again, about life itself - is it a fluke, following no blueprint but it's own DNA, a mutation of the evolution of our galaxy?

What protects life here is our Magnetosphere. You can see the solar winds in this picture hitting our EMF or electro-magnetic field which protects us in layers, sending the majority of cosmic radiation out and around us. So again, our sun, this close star, can eradicate a world. But a combination of many things keeps us from looking like Mars.

So let's look at Mars. I chose this picture because of the amazing mountain range shaped like a human face, but of course, re-shaped with the shadows. Anyway, Mars has no atmosphere because the Sun ripped it away. Mars has no magnetosphere. Our star destroyed it, radiated the planet, yet we've managed to get there using incredibly intelligent "scientist robots" and many cosmologists know we can colonize Mars. I'm off topic:

Sol, our star, the sun, has a corona surrounding it and expanding out into space about 100 millions miles. In that corona exists something called CME (Coronal Mass Emissions) which are exactly what they sound like. Hugh ejections of solar radiation, flares, prominences, SUPER storms, SUPER flares, just a mind-numbing amount of power - which we should be using more to our advantage. Also, it's the reason the outer sun is hotter than the inner. Sun-spots affect flares and prominences too. The first picture in this post is a real picture of prominences jetting hundreds of thousands of miles into the corona then falling back into the sun.

The Sun has it's own Electro-magnetic field too, and a great amount of gravity, enough to keep all the planets in orbit. When an object like an asteroid from between Mars and Jupiter is bumped out of orbit, it careens out and DOWN, following gravitational pull, and we see alot as "shooting stars" but I assure you they are FAR from stars. If they were, they'd burn us up into a cinder.

By the by, every picture here that looks obviously real, is.


So the next time you wish upon a star, why not make it the one you know best? Our Sun.

Fascinating text, and much needed, it is good to be reminded all the time of the power of our SUN. And you explain it all so well. Yes, the implaccable burning blue overhead, and all the sun worshippers at the beaches, they should all be reading your blog.

Cathy said...

CELESTE: Not for nothing did our ancestors pay tribute to this unquiet orb. It's just so amazing how fragile earth is, being so close to a star.

The set of coincidences that allows for what we call life, is why theology sells! The infinte calculations that made this thing happen is more than outstanding ... it is near supernatural!

EMF ... ooh, your Unbelievable!!

John Hayes said...

Wonderful post--so muuch to contemplate here. If I ever knew about the magnetosphere, it's something I forgot long ago! Thanks.

Gerry said...

I love to come to your blog because I read about things I don't know much about. I am so glad you love the stars, Cathy, and like to inform people a little with pictures yet. I read down through other entries I had missed. The meteor showers. It is so awesome to think there is so much out there we little mites on earth just look up and marvel. And try to understand, some a whole lot more than others. Gerry

Cathy, what a wonderful post! Each and every time I visit your blog, it peaks my interest even more about Astronomy. My husband, nephew and daughter are astronomy buffs.

Cathy - great posting. I loved it. I don't remember who introduced me to the knowledge that we are exploded star stuff. So hard to imagine how unlikely were all the odds that put life, of any type, on this planet much less the odds that put life that CAN type on this planet.

It really is mind blogging.:)
All the power of nature/natural, yet we destroy and toss aside natural power---too cheap! I often star gaze, cloud ponder, and easily understand why people used to feel the hand of God (s) (ess)

Celeste Maia said...

Thank you for your great comment in my blog. I think Duarte made a pun on the "think global, act local" comment, he changed it to "...act global" on purpose. I also share your optimism, Cathy.

Selchie said...

Interesting post, yes the existence of solar flares kind of debunk the global warming myth dont they.
As for mars I heard a rumour there already was life there, something about track marks appearing around the 1970's.
Gotta love the sun, perhaps eventually we'll get some sense and begin to use it for energy down here.

have a great weekend lovely,

Cathy, you are intense! Call me simple but sometimes I just like to walk outside and hum:
"My, oh my, what a wonderful day
Plenty of sunshine headin' my way
Zip-a-dee-doo-dah, zip-a-dee-ay"

Caregivingly Yours, Patrick

Reading about the planet WASP-18b makes your entry even more impressive.

Joseph Pulikotil said...

Hi Cathy:)

Greetings:)

I am amazed at the wealth of knowledge you have so beautifully presented here embellished with awe inspiring photos.

In a nut shell, I would like to say that all this is a MARVEL OF GOD and we have only scratched the surface. There are more unfathomable mysteries waiting to be discovered.

This is a very special post because you are the first person I have visited so far who is explaining with amazing clarity and deep insight into the solar system.

I am astounded at the breath taking information you have garnered.

Have a wonderful day Cathy:)
Joseph

Ben said...

Middle-aged and potent surely is a combination fraught with potential dangers. I hadn't known about the magnetosphere, but you make it make sense, Cathy. I always end up learning things from you. Thanks for another great post.
