Stellarium Mobile is a planetarium app that shows exactly what you see when you look up at the stars.

Identify stars, constellations, planets, comets, satellites (such as the ISS), and other deep sky objects in real time in the sky above you in just a few seconds, just by pointing the phone at the sky!

This astronomy application has an easy to use and minimalist user interface, that makes it one of the best astronomical applications for adults and children who want to explore the night sky.

Stellarium Mobile features:

• View an accurate night sky simulation of stars and planets for any date, time and location.

• Dive in a collection of many stars, nebulas, galaxies, star clusters and other deep sky objects.

• Zoom on realistic Milky Way and Deep Sky Objects images.

• Discover how people living in other regions of the planet see the stars by selecting the shapes and illustrations of the constellations for many sky cultures.

• Track artificial satellites, including the International Space Station.

• Simulate landscape and atmosphere with realistic sunrise, sunset and atmosphere refraction.

• Discover 3D rendering of the major solar system planets and their satellites.

• Observe the sky in night mode (red) to preserve your eyes adaptation to darkness.

Stellarium Mobile contains in-app purchases allowing to upgrade to Stellarium Plus. With this upgrade, the app will display objects as faint as magnitude 22 (versus magnitude 8 in the base version) and enable advanced observing features.

Stellarium Plus features (unlocked with in-app purchase):

• Reach the limit of knowledge by diving in a massive collection of stars, nebulas, galaxies, star clusters and other deep sky objects:
  - All known stars: Gaia DR2 catalog of over 1.69 billion stars
  - All known planets, natural satellites and comets, and many other minor solar system objects (10k asteroids)
  - Most known deep sky objects: a combined catalog of over 2 million nebulas and galaxies

• Zoom almost without limits on high resolution images of deep sky objects or planetary surfaces.

• Observe in the field, even without internet connection, with a "reduced" set of data: 2 million stars, 2 million Deep Sky Objects, 10k asteroids.

• Control your telescope through WIFI: drive any GOTO telescope compatible with NexStar, SynScan or LX200 protocols.

• Prepare your observing sessions using the advanced observation tools, to predict a celestial object observability and transit times.

Stellarium Mobile is made by the original creator of Stellarium, the well known open source planetarium and one of the best astronomy applications on Desktop PC.

Such a Joy to Use!

This app is such a joy to use! I’m not an astronomer, I don’t have a telescope or anything more than my iPhone’s night mode, but I do have the good fortune to live in a light free area where the panoply above me is regularly on view. When I wander around at night or early in the morning, Stellarium opens up the omniverse for me, showing and naming the constellations and stars that would otherwise just be little lights. Through it, I have started to appreciate the vastness that surrounds us, even to understand how different cultures saw what I can see, so that it places me both physically and historically. I don’t know of any better way to use a smartphone than that. A totally unique application. Kudos to the developers!

Fantastic, exactly what I want.

This app is every stargazing tool I could want. It has extensive features even in the free version. I found the interface intuitive and spectacularly useful for identifying planets, constellations, and even individual stars.

I learned a lot from the included descriptions of each constellation, but wish it was a little bit easier to read, maybe with just a couple headings separating mythology and interesting features and linking the Wikipedia entry instead of just loading a block of text.

I also happen to love the fact the architecture is open source, and that they offer a lifetime price for the pro features. Good vibes all around!

Outstanding Astro Application

Stellarium is by far the best general purpose astronomy application for iPhone. It is really cool, going out with binoculars and identifying various stars, star clusters and nebulae. We travel extensively between the northern and Southern Hemispheres. I’m looking forward to going back to the temperate south in a couple weeks to use it to locate the southern star clusters and Milky Whey features. While the paid version brings many more stars, Stellarium does not big down, allaying previous concerns.
I again look forward to the rapid location of the Magellanic clouds, omega Centauri &c.
