It takes up to 30 minutes for your eyes to adapt to the dark. And a country location is best. Then, on a clear night with no moon ... how many stars?

What's the most distant human object?

The most distant human object is now over 13 billion miles (21 billion km) from Earth.

What are star trails, and how can I capture them?

When a camera captures a star's movement across the sky, it's called a star trail.  An astrophotographer explains how he does it.

What are star trails, and how can I capture them?

Ken Christison captured these glorious star trails around Polaris, the North Star. He wrote, “For the most common and often the most spectacular star trails, you want to locate Polaris and compose the image so it is centered horizontally and hopefully you can have a bit of foreground for reference.”
