natsmada4fjr,Thanks for sharing this! I've lived in MinneSNOWta for 13 years and have NEVER seen the "Aurora Borealis", but now I don't have to.
Damir,red's comment above triggered my curiosity to find out how this light spectacle is created (who knew, check, learned something new and amazing today):
yes old news, but new to me since astronomy was a bit too abstract to me, therefore I never explored that science. Recently watched the movie Interstellar and was trying to wrap my head around "leaving one dimension and entering another" and "when the time stands still and you don't age"...hmmm, a bit too complicated :smile2:Damir,
Now you can please go back and kick your "teachers" in the shin for me, just once, very hard. :wink:
None of this stuff is breaking news. Yeah, there is still more science to learn, but we know the basics there.
We still do continue the research, because when the Sun sneezes, the Earth can catch a cold.
Solar flares can wipe out our satellite signals, and some satellites we just shut down briefly,
to prevent electrical damage from an approaching strong solar flare, until it passes by.
In the video "How the Northern Lights are Created," I would question the spoken timeline
for a solar flare (or solar storm) to reach each of the inner planets.
"Why" is a whole 'nother story, but it's all fun stuff to learn.
Damir,It's just interesting how even minor solar eruptions soooo far away from Earth can influence our planet so much....let's just hope there won't be any "major and catastrophic" solar events in our future :wink2:
p.s. I am guessing you are also skeptical about movies that are based on true story like Star Wars? :grin2: :wink2:
Red, I suggest we (or you) start a new thread (i.e. Astronomy simplified) in General chat, it's a very interesting topic and I think it deserves it's own place for discussion. Otherwise it will get buried (here) and hard to find on this forum.Damir,
Please fasten your seat belt . . . :lol:
Since I mentioned the distances from the Sun to the planets, there is a relationship there. Each planet in our Solar System is about twice (with a fudge factor) as far from the Sun as the last planet going inward. Venus is about twice as far from the Sun as Mercury, et c. That goes for each planet, until you get to Mars. Twice as far from the Sun as Mars orbits, there "should" be another planet there, and twice as far as that orbital distance, then you get to Jupiter. The planet between Mars and Jupiter just is not there. Instead, we have the Asteroid Belt, which is a collection of rocks in that orbit, maybe enough rock material to assemble a planet. If something happened there (like what the Death Star did to Alderaan) in ancient times, the Asteroid Belt would be the result. So when Solo arrived at the orbit of Alderaan, he found that there was nothing left but an asteroid field. Of course, nobody can say if that really happened here or not. It's an old speculation that popped up once we realized the distances between the Sun and the planets have a relationship. There is a planet "missing" from the progression, but we have the Asteroid Belt in that orbit instead. That old idea came long before the Star Wars movie.
The meteorites that fall to Earth are sometimes stony, and sometimes metallic. Earth's crust is stony, and the core is metallic. If an Earth-like planet was actually destroyed in some way, you would have some stony asteroids, and some metallic asteroids. It's all speculation, but until we start mining in the Asteroid Belt, nobody has a real answer. As far as the possibility of such ancient weapons, we have found that the atmosphere of Mars has radioactive elements that we can not explain by any natural causes, but only as the result of nuclear bombs.
Strange stuff . . .
