What is "What's Up?"

In "What's Up?" you can read and learn about what you can see in the night sky. Each month astronomer Tom Callen publishes an article about what's happening in the heavens, including star maps and astronomical facts.

You also get tips on what you can see by naked eye, or with ordinary binoculars.

Frederick's Glory
Antiquity´s first star catalogue described the then 48 known constellations; all of them were in the northern hemisphere. Others have been formed since then and there are even some that have fallen into the obscurity of time as in the case of this month´s example.

And One Brought A cooking Pot
Different people from different ages and places on Earth have interpreted the night sky in different ways. This month we look at one such well-known example from Native Americans who lived in the northeast United States.

Christmas Eve
Chill December with its deepest dark of the year has rolled around once again and as we have done in the past it´s time to take a look at Christmas Eve´s night sky, a tradition since “What´s Up?" started in 2002.
