Did you see a light in the sky that you couldn't identify? What's Up! helps you find out what you saw by answering a few simple questions about your observation.

With help of What's Up!, you can easily identify stars, planets, airplanes, satellites, meteors and much more.

Have you ever seen a UFO (Unidentified flying object)? In most cases these sightings can easily be identified as something natural or man-made. Venus for example often looks like an exceptionally bright, stationary light in the twilight sky. A bright star like Sirius or Canopus can twinkle so much that it looks like it's boiling and changing colours rapidly. Meteors or bolides can be seen as a bright flashes, often leaving a trail. And did you know sky lanterns or migrating birds sometimes look like a formation of lights moving in the sky at night?

What's Up! helps you identify your sighting by answering a few questions about your observation. All sightings feature an illustrative picture, a description of what the sighting normally looks like when seen in the sky, and some background information. Of course you can share your sighting with your social network.

Keep looking up!

Ratings and reviews

hardly asks any questions, and the questions that were asked were hardly ones that I imagine would be necessary to determine what was really seen. the app kept suggesting that I saw a flock of birds , even though it was clearly a red flashing light in the middle of the night. didn't bother asking the color of the lighr, the distance from me, my location etc. totally useless app. I was really hopeful too because its such a great idea. just horrible made.

Ok so i saw a thing that looked like a very very large shiny satelite just west of puerto rico. twilight and it was catching the sun. It moved steadily above all cloud layers, then made an instant 110°ish rotation and kept going without any curve. Straight angle change and no deceleration, it did that twice more in odd directions and then flew off across the horizon. And was gone in 3 seconds flat (accelerating) .. ...it was not a flock of birds!

The astronomy app in question offers a deep dive into the cosmos for those willing to explore. While it may have a steeper learning curve, its complexity can be seen as a strength for more experienced stargazers. With a vast database of celestial objects and detailed sky maps, this app can be a treasure trove for astronomy enthusiasts. It challenges users to expand their knowledge and navigate the heavens with determination. However, it might benefit from more user-friendly features and tutorial
