فیلم زیبا از شفق قطبی

شفق قطبی بسیار زیبا


[]


شفق قطبی از چشم ایستگاه فضایی بین المللی (از ناسا)


شفقهای قطبی نورهای زیبایی هستند که به طور طبیعی در آسمان دیده میشوند. که معمولاً در شب و در عرضهای جغرافیایی قطبی به چشم میخورند. آنها در [یونوسفر] تشکیل میشوند و سپیده دم قطبی قابل مشاهده هستند. در عرض جغرافیایی قطب شمال به آنها شفقهای شمالی نیز گفته میشود که این نام بر گرفته از نام ایزدگونه رومی سپیده دم و نام یونانی باد شمالی است که در سال ۱۶۲۱ توسط پیر گاسندی روی این پدیده طبیعی گذاشته شد. به شفق های قطبی، نور قطب شمال هم گفته می شود زیرا آنها فقط در نیم کرهٔ شمالی رویت می شوند و هر چقدر به قطب شمال نزدیک می شوید با توجه به مجاورت با قطب مغناطیسی شمالی زمین احتمال بیشتری میرود که بتوانید آنها را ببینید به طور مثال در شهرهای شمالی کانادا که بسیار نزدیک به قطب هستند امکان رویت آنها بسیار زیاد است.

Its like you read my mind! You seem to know a lot about this, like you
wrote the book in it or something. I think that you can do with some pics to
drive the message home a bit, but other than that,
this is great blog. An excellent read. I'll definitely be back.

Nice post. I learn something new and challenging on websites I stumbleupon every day.
It will always be interesting to read articles from other writers and use a little something from
other web sites.

An intriguing discussion is worth comment. I believe that you
should publish more on this topic, it may not be a taboo matter
but typically people do not speak about these subjects.
To the next! Best wishes!!
