Frequently Asked Questions
How do I get started?
Simply open CosmicDaily and you'll see today's astronomy picture! Swipe through the image and read the expert explanation below. New content appears daily at midnight EST.
Do I need a NASA API key?
No! CosmicDaily works out of the box with our demo key. However, if you're experiencing rate limits, you can get your free personal API key from api.nasa.gov and add it in Settings.
Can I use the app offline?
Yes! CosmicDaily intelligently caches images and data. Once you've viewed an image, it's available offline. The app will show cached content when you don't have an internet connection.
