شب پرستاره - مسابقات رصدی
نجوم و هوافضا
گستره اجرام
پهنه راه شیری، جایی که خورشید ما در یکی از بازوهای آن بر گرد مرکز در چرخش است با اجرامی زیبا که دل هر بیننده ای را مجذوب خود می کند، تصویر فوق نیز نگاهی بر مرکز این کهکشان دارد، اجرام بسیار زیادی در این تصویر ثبت شده اند که نشان از شیوه دقیق و پرحصله در عکاسی از آسمان شب است.

When to plan your Star Party
An evening with nice weather, few clouds and a Space Station sighting opportunity is best. Check for the best International Space Station sighting opportunities in your area and plan your party around that opportunity.

Where to plan your Star Party
A local museum or observatory, a park or an open field, or even your own backyard are good places to throw a party. Have a facility available to go inside, and enough activities to entertain the kids if the weather turns bad. You can always go back outside when the weather clears. You may also want to check weather related Web sites for forecasts of your area.

Viewing the Stars
Even though you want the highlight of your party to be the International Space Station passing overhead, you also want to allow plenty of time for stargazing. Rent or borrow a telescope and be sure to have a constellation map nearby.

You could allow the following time for each activity for a 2 ½ hour party agenda
20 minutes Greet arrivals, socializing for adults, free play time for kids
20 minutes Refreshments
30 minutes Arts and crafts for kids
30 minutes Organized games, activities and space trivia
30 minutes Stargazing and watching the Space Station fly overhead
20 minutes Socializing for adults, free play time for kids

Star Parties have been an important part of the amateur astronomy scene for some time. These events attract hundreds, even thousands of enthusiasts, offering the chance to see planets, seasonal constellations, deep sky objects and the moon. They usually cater to the entire family and often feature activities for the kids. Many events are held every year all across the nation. Initially, astronomy clubs intended to have their own local or regional stargazing sessions, but now some of these have reached such popularity that they attract crowds from across the country and abroad.

Did you know the Space Station orbits the Earth every 90 minutes?
You don't have to wait for a major Star Party in your area to view the wonders of the night sky. Why not throw your own Star Party? And why not plan it on a night that the International Space Station is passing over your city?

The Space Station can be seen with the unaided eye or through binoculars, if the weather conditions are right. It will appear as a steady white pinpoint of light moving across the sky. You will need only telescopes at your party to view other celestial objects in the sky.

NASA SkyWatch shows first-time users when and where to look to see the Space Station. For help with sightings opportunities go to the Quick Start Guide.

Imagine the excitement of your party-goers when they look to the sky and point out the Space Station flying overhead!
