Message from Sky & Telescope


Welcome to the new Sky & Telescope web store. We’ve been offline since August but are thrilled to be back up and running.

Transitioning our web infrastructure from the previous owner proved to be much harder and more complicated than we imagined. We apologize to each and every one of you for this delay, but we took our time to make sure everything would work correctly so that your browsing and purchasing experience is as easy as possible. We may not be Amazon, but our goal is to bring you unique products as easily and quickly as possible. We view ourselves as part of the community we serve, so getting things right is important.

As you know, the Sky & Telescope team works hard to bring interesting, valuable, and fun products to you, our community of astronomy enthusiasts. In the coming months we will roll out some new items as we get them developed and produced (like the eagerly anticipated eclipse-track Earth globe — it’s awesome!). If you have ideas about other items you might like us to produce or carry, let us know. Although we can’t promise to do everything, we’ll carefully review any ideas we receive.

Thanks for your ongoing support of Sky & Telescope!

Sky & Telescope's Mars Topography Globe

Format: Globe


Explore the Red Planet's highest volcanoes, largest impact basins, and deepest canyons with this updated 12-inch-diameter topographic globe of Mars. Derived from millions of laser-altimeter measurements by NASA's Mars Global Surveyor orbiter, this data set has revolutionized our understanding of Martian geology. Elevations are color-coded for easy identification, and more than 150 surface features are labeled with their official names. This updated globe includes the landing sites for the Spirit, Opportunity, Phoenix, and Curiosity rovers.

Mars should be nicknamed the Lumpy Planet because it displays such a wide range of highs and lows — and S&T’s topography globe uses a color scheme to show these elevation changes. For example, the white summit atop the Olympus Mons, the solar system’s largest known volcano, indicates that it is nearly 22 km (72,000 feet) high — 2½ times taller than Mount Everest! The white summit gives way down its flanks to brown, pink, and finally yellow, before flattening out into the green of Lycus Sulci and, farther west, the rich blue of the deep regional depression Amazonis Planitia.

Did You Know?
Hellas Planitia, a huge blue-and-purple feature on S&T’s Mars Topography Globe, is the solar system’s largest visible impact basin. It’s 2,300 km (1,400 miles across)!
