Where's Kepler Looking?
Kepler, a space-based telescope, is searching for worlds that could possibly be similar to our own. NASA's Kepler mission is continuously monitoring over 100,000 stars in the Summer Triangle and will continue for a period of at least four years.

What a lot of people don't know is that you can see the area in the night sky where Kepler is searching. We recommend you contact your local astronomy club to help you find and explore the area. If you'd like to try to see it on your own, you can use our free resources.

Here are the basics of finding the area where Kepler is searching:

  • Using the graphic above, go outside about an hour after sunset and look toward the northeast to find the Summer Triangle. The points of the Triangle are marked by the three bright stars Vega, Deneb, and Altair.
  • The area of the sky where Kepler is searching for Earth-size planets is just a little larger than your fist held at arm's length. Now, hold your fist out at arm's length, between the stars Vega and Deneb.
How many stars can you see in that area? Well, Kepler can see thousands!
