ASTRA: Celestial Atlas

Explore black holes, exoplanets & stars — now with nightly reminders for ISS flyovers, eclipses & meteor showers.

Look up.

Right now, above your ceiling, the International Space Station is racing across the sky at 27,000 km/h. Jupiter is glowing in a constellation you can't name yet. A star whose light left before you were born is arriving at your eyes tonight.

ASTRA helps you see all of it.

Lift your phone to the sky and the universe unfolds in augmented reality — every star named, every planet placed, every constellation drawn in light. Catch the ISS the moment it passes overhead. Rewind the sky to the night you were born, or fast-forward to the next eclipse. And whenever you wonder "what is that?", just ask — ASTRA's AI astronomer is always listening.

No telescope. No expertise. No light-polluted excuses. Just you, your phone, and a universe that's been waiting for you to notice it.

Your personal universe starts here.
