We have selected Astronomy Magazine as the world's very best website on Astronomy.

Astronomy Magazine is published by Kalmbach Publishing, based in Waukesha, Wisconsin, USA. Astronomy Magazine was launched in 1973 by Steve Walther, then aged 29. Sadly Walther died of a brain tumour just three years later, but his magazine grew under his successors to become the largest circulation astronomy magazine in the world. It was bought by Kalmbach Publishing in 1985.
