[edit] Q about astronomy

When looking at the night sky, are all the stars that are visible with just the naked eye, from our own galaxy? Mortene 13:28, 4 October 2005 (UTC)

Yes and No. If you are in the Southern Hemisphere, you will be able to see the Large Magellanic Cloud and the Small Magellanic Cloud, which are separate galaxies. All over the world, you can see galaxies with the naked eye (if you are in a place with low enough light pollution) but you would probably think that they are single stars....

The Andromeda Galaxy is also visible to the naked eye, as are other members (those more closely related to the Magellanic Clouds) of the Local Group. I suspect the "yes and no" of the previous answer largely relates to the fact that while you can see extragalactic stars, you can't see individual extragalactic stars. However, the interesting case of Andromeda is that, around 120 years ago, a single extragalactic star (supernova S Andromedae) became naked-eye visible with a magnitude of 6. — Lomn | Talk / RfC 14:58, 4 October 2005 (UTC)

Thanks for the replies! Very interesting, and just the kind of response I was hoping for. Mortene 07:45, 5 October 2005 (UTC)

[edit] what is operating system

به غم کسی اسیرم که ز من خبر ندارد   عجب از محبت من که در او اثر ندارد

 غلط است هرکه گوید دل به دل راه دارد  دل من زغصه خون است دل اوخبرندارد                                        

به سوز و غم عشق لایق بمانم

ز کوی محبت مرانمالهی

کرم کن کنار شقایق بمانم

• دلم تنها ترین دلهاست اینجا
• که از دست رفاقت تیر خورده
• دلم با پای خسته لنگ لنگون
• تن زخمیش از کوی تو برده
