Interactive Sky Chart (Beta)

Launch our new and improved Interactive Sky Chart!

We have moved our interactive sky chart off of Java and onto an HTML5 platform to create a seamless experience for our users. Now you can create your own custom map of the sky from any browser, including on mobile devices.

Powered by Heavens Above, our interactive viewer charts the sky as seen by eye, including the Moon, stars brighter than magnitude 5, the five bright planets (Mercury, Venus, Mars, Jupiter, and Saturn), and deep-sky objects that can be seen without the use of optical aid.

Chart the stars and planets visible to the unaided eye from any place on Earth, at any time of day or night, on any date between the years 1600 to 2400  Simply enter your location, either via zip code, city, or latitude/longitude, and find out what's up in your sky tonight! Change the selected view by dragging the green square on the full-sky chart.

Customize your map to show (or not show) constellation lines, names, and boundaries, deep-sky objects, star and planet names, and more. We also now offer the option to turn off the Sun, in order to show which stars are up during the daytime. And don't forget to experiment! Discover the difference between equinox and solstice, and find out if the constellations really are upside down on the other side of the equator.

Note: We are releasing this new-and-improved sky chart as a beta. If you have questions or wish to report bugs, please email us at help@skyandtelescope.com.

Like what you see here? You'll get an even bigger, accurately mapped sky chart, along with oodles of stargazing information, in the pages of Sky & Telescope magazine and in our annual SkyWatch.
