I first wrote about this about five years ago, and I still think it’s really neat. At Heavens Above, you begin by selecting your location. It will then tell you where everything is in the sky. This includes stars, planets, satelites, and space vehicles. Want to see the International Space Station? If you’re in Cleveland, your next chance is May 31 at 4:49 AM. At that time, it’ll be in the Southeast at 14 degrees.
The brightest satelite in the sky tonight will be Lacrosse 3, a military recon satelite launched in 1997. You can see it at 10:30 tonight in the Northeast sky, at 39 degrees.
You can also get whole sky charts, look at constellations and planets, and track the Voyager and Pioneer spacecraft.
