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.
This sky chart is mobile-friendly — it detects the size of your browser window when you first load the page and fits page elements accordingly. However, if you resize your browser window for any reason, you'll want to refresh the page so that it loads in a way that's optimized to the new window size.
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 email@example.com.
If you miss the old sky chart, you can still find it here: Legacy Interactive Sky Chart. Please note that this version runs on Java, so it will only run in Internet Explorer and Safari browsers. Run at your own risk: We are no longer supporting this version of the sky chart.
