Staring at the starry night sky? Get a little help from these astronomy apps

People have been staring at the starry night sky ever since the world began, wondering what it all means. While previously, you could only analyze constellations with charts, maps, and telescopes — or pay a visit to the nearest planetarium — today you can use mobile apps to uncover a vast amount of information about what’s happening overhead at any given time. Backyard stargazers use apps to discover a wealth of information on the location and identity of planets, stars, and galaxies — no telescope needed.

The best astronomy apps use the gyroscope and compass in your smartphone or tablet, along with date, time, and location services, to determine your whereabouts. While an internet connection is helpful, it’s not always strictly necessary for every app. If you’re in the wilderness, far from a Wi-Fi or cell connection, you can still benefit from astronomy apps. Some also use augmented reality through the device’s camera to show you exactly where stars are positioned. Most apps are extremely easy to use and targeted to beginners and enthusiasts — just point your device’s camera toward the heavens and find the stars and constellations.

Inspired to see what’s overhead? Here are a few of the many cross-platform iOS and Android apps we discovered.

Star Rover

Star Rover acts as your device’s built-in planetarium. Just hold up your phone, use a pinch-to-zoom gesture, and have the app pinpoint whatever is up there. After determining your position, the app locates stars, the moon, planets, and constellations. The sky map updates dynamically as you move your phone around the block, neighborhood, or region to see twinkling stars, nebulae, meteors, and sunset glow. Star Rover, which costs $2, catalogs over 120,000 stars, all 88 constellations, planets and their moons, moon phases, and real images of Messier objects. Detailed information covers sky objects, equatorial and azimuthal grids, the Milky Way Galaxy, sunrise and sunset, eclipse simulation, and more.



With SkySafari, all you have to do is hold your device up to the sky and let the app quickly assemble planets, constellations, satellites, stars, and deep sky objects. Featuring interactive information accompanied by rich graphics, the app lets you view 120,000 stars; more than 200 star clusters, nebulae, and galaxies; all major planets and moons; and a variety of asteroids, comets, and satellites, including the International Space Station (ISS). You can use the app to animate a variety of celestial events such as meteor showers, comet approaches, transits, and conjunctions. SkySafari lets you simulate the night sky from anywhere on Earth and move backward and forward in time. Rich graphics show you detailed views of galaxies and constellations. The Tonight’s Best feature highlights the most interesting current events.


SkyView Lite

You don’t need a telescope to see the stars and constellations as long as you have Sky View Lite, an intuitive free mobile app that helps you find and identify sky objects like stars, planets, and satellite flybys from the likes of the International Space Station and Hubble Space Telescope any time of the day or night. An augmented reality feature lets you use your camera to spot objects in the sky at any time. The app also features sky paths for tracking objects, and a social feature that lets you share discoveries with friends and family. There’s no need for Wi-Fi, cell, or GPS  — the app functions fine without them.
