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. ———————————————— - AR SKY VIEW — Point your phone up and watch the night sky come alive with names, myths, and motion. - LIVE ISS & SATELLITE TRACKING — Follow the space station and 50+ satellites in real time. Never miss a flyover again. - TIME TRAVEL — Wind the sky to any date. Revisit a meteor shower, preview an eclipse, or find the stars from a moment that mattered. - PLANETS & NAKSHATRAS — Real astronomical positions of the planets and all 27 Nakshatras, precise to the moment. - ASK ASTRA — Your own AI astronomer for black holes, exoplanets, and every "why is the sky like that?" question. - EXPLORE THE COSMOS — Fall into black holes, hunt for exoplanets, and drift through a gallery of breathtaking NASA imagery. ———————————————— The sky is the oldest thing humans have ever looked at.
