The City Skies program seeks to point out that the night sky is available to everyone, everywhere without special equipment. This project prepares neighborhood and community leaders in Philadelphia to use simple but effective observation tools and NASA's educational web content to help their inner-city Philadelphia neighbors learn about space science and technology—and about their city and themselves—by knowledgeably exploring the sky.
Observing the Night Sky
What can you see in the sky tonight? Unsure how to navigate the night sky? These resources can help.

Where can you observe in Philadelphia?
There are interesting things to see in the night sky no matter where you are in Philadelphia. Some spots are better than others for using your telescope to look at the night sky. Look for areas without too many trees. We suggest: baseball & football fields, school yards, parking lots, parks, waterfront areas and hilltop locations. Below we suggest some good locations for observing around Philadelphia.
- Ridge Ave at Hermit Street
- Lemon Hill
- Belmont Plateau, Fairmount Park
- Joel N. Bloom Observatory at The Franklin Institute
What do you need to bring with you when you go observing?
Go through this checklist before heading out the door!
- Check the weather
- Dress warmly (if necessary)
- Sky Map or Chart (hard copy or smartphone app)
(Notice any patterns?)

City Skies Scientists
Dr. Christopher Hamilton is a research associate at NASA's Goddard Space Center. Dr. Hamilton's research focuses on geological surface processes that can help us better understand the evolution of the Earth and other planetary bodies. His expertise lies in the study of volcanoes, specifically lava flows, magma-water interactions, explosive eruptions, and more. He conducts his research by using a combination of field observations, remote sensing, geospatial analysis, and geophysical modeling. He hopes to provide insight into how planetary surfaces, interiors, and atmospheres evolve through magma production, and how these processes are different for other climate systems.

William Dean Pesnell
Dr. Pesnell is a project scientist for NASA's Solar Dynamics Observatory (SDO). The Solar Dynamics Observatory's mission is to understand the sun's variations and how they influence life on Earth. The SDO learns about how the Sun's magnetic field is generated and how the energy it creates is converted into solar wind and energetic particles.

NASA also offers videos to help you uncover the mysteries of the Sun!
Did you know that Galileo tracked the motion of the Sun by studying sunspots? By doing this, he realized the Sun rotated on its own axis! Have access to a Sunspotter? The University of Texas - Pan American has put together an activity that allows you to follow Galileo's lead and track solar activity with your friends and family!

Planning a Star Party
It's easy to throw an observing party! Here's a checklist for the materials you'll need, what you should do before the event, and tips for running a successful star party.
Prior to the day of the event:
- Be sure to distribute the flyers early and often!
- Practice looking up and seeing things. Also work with any materials (sky maps, etc.) you will be using, so you are comfortable with them.
- Practice questioning your friends and relations for their observations and ideas.
- Make sure you have engaged more than enough support staff for your anticipated crowd!
- Begin tracking the weather forecast three days before the big event.
- Consider what you'll do if the weather doesn't cooperate.
- Anticipate the crowd flow. Plan where to position your materials, way-finding signs, astronomer, and support staff.
- Look around the best location to position the telescope and for all to see the sky well.
- Will you need any additional illumination for walking, say on paths or near the materials table?
- Alert the facility to the expected crowd. Anticipate basic building functions:
- Do you know how to turn on/off the lights?
- Do you know who has a key to the facility?
- Do you know how to unlock the bathrooms? Turn on the water?
- Do you have enough toilet paper?
- Locate the closest electrical outlet, just in case the astronomer needs one.
- Locate the tables and chairs that you will need, trash cans, and maybe a few large rocks to prevent papers from flying away.
- Make sure you prepare way-finding signs. Copy any materials that you need. Cut the red film into flashlight-sized squares.
Materials to have on hand:
WE GAVE YOU:
- Star Wheel
- Positioning Card to help participants locate and identify Jupiter this spring and summer
- Red film to cover flashlights brought by participants.
- Handout for making astronomical measurements using your hand for scale
- Moon image (if you want to use it)
- 20 small red flashlights
- 365 Starry Nights by Chet Raymo which gives you a picture of the sky for every night of the year.
- Discover the Stars by Richard Berry which gives you an introduction and guide to star gazing.
YOU MIGHT ALSO WANT TO HAVE:
- Flashlights (with red film)
- Tape or Rubber Bands to hold red film on participants' flashlights
- Materials to do any other activities in your plan
- A map of this month's sky.
On the day of the Star Party:
- Prepare for participants' arrival.
- Check the weather forecast! Activate your contingency plan for poor weather, if needed.
- Get there early—at least an hour before participants will arrive.
- Unlock the facility.
- Prepare the staff for their roles.
- Put out any way-finding signs you think the participants will need (bathrooms, parking, etc.).
- Make sure bathrooms are unlocked, that water is turned on and ready for use.
- Set up any tables, chairs, trash receptacles, additional illumination.
- Set up materials for distribution (prevent them from flying away).
- Remind yourself of some of your favorite questions with which to facilitate.
- Go on out there and engage some people in looking up.
- Oh yes, have fun!
Star Party Activities
In case of inclement weather, malfunctioning 'scopes, etc., make sure you have substitute activities to ensure a stress-free, fun, and educational event, regardless of unexpected itinerary changes.
