Android apps · live data from NOAA, NASA, CelesTrak & Breakthrough Listen

Know what's happening above you.

Four companion apps for the sky. Watch the Sun's storms head for Earth, catch the ISS crossing overhead, see which asteroids are passing by this week, and find the stars we've listened to for alien signals.

Solar

Solar: Sun, Aurora & Eclipse

Space weather you can actually read. A live view of the Sun with every numbered sunspot region, and a clear warning when a flare or CME is on its way to Earth.

  • Live Sun
    NASA SDO imagery with numbered active regions, rotated to the current time.
  • Earth
    An animated magnetosphere showing what the solar wind and CMEs are doing to it right now.
  • Aurora tonight
    A go, maybe or stay-in score from aurora chance, cloud cover, darkness and the Moon.
  • Eclipses
    How each coming eclipse will look from where you are.
  • History
    A calendar back to 1818 for sunspots and 1932 for geomagnetic storms.
  • Alerts & widgets
    Notifications with your own thresholds, plus six home-screen widgets.

Overhead

ISS & satellite passes

Never miss the ISS again. Overhead works out every pass from your location, tells you how good it will look, and points your camera to where it will appear.

  • Pass predictions
    Rise, peak and set times with height and brightness for the ISS and other satellites.
  • Viewing score
    Each pass rated 0–100 from height, brightness, darkness, Moon and cloud.
  • Look
    Hold up your phone and the camera view marks where to watch.
  • Radar
    A 3D Earth with satellites circling it in their real orbits.
  • Planets & night vision
    Mercury to Saturn on the sky chart, and a red mode that keeps your eyes dark-adapted.
  • Widgets & alerts
    Next-pass countdown, upcoming passes and a live map on your home screen.

Asteroids & Meteors

Near-Earth flybys and meteor showers

See what's passing Earth this week. Every close approach on a live radar, real impact-risk data from NASA, and a 3D flyby you can ride alongside.

  • Radar
    A live dial of this week's flybys, with the next one counted down.
  • 3D flyby
    Follow an asteroid past Earth on its real path, with the true Sun, Moon and stars.
  • Risk
    NASA's Sentry list of objects with any chance of impact, explained plainly.
  • Meteors
    Showers with real radiants and rates, plus recent fireballs.
  • Sky
    Point your phone up to find stars, planets and asteroids.
  • History
    A calendar of close approaches from 1900 to 2200.

Sky

Night sky & the search for alien signals

Your night sky, with the search for life running through it. See what's up tonight, then find the stars that radio telescopes have listened to for a signal.

  • Tonight
    A live horizon scene with the real Moon, planets and meteors, and a 0–100 stargazing score.
  • Sky map
    A star map that follows your phone, with a slider to wind the sky 12 hours either way.
  • Listen
    Over 5,500 stars and 94 galaxies that Breakthrough Listen pointed the Green Bank Telescope at.
  • Our radio bubble
    A 3D view of the stars close enough to have already heard our broadcasts.
  • Signals
    The Wow! signal, BLC1, fast radio bursts and more, marked solved or still unexplained.
  • Calendar
    Moon phases, meteor showers, eclipses and the days Green Bank was listening.

Built the same way

Your sky, your phone. Nothing leaves it.

No account

Open the app and it works. There's nothing to sign up for.

No tracking

No analytics, no ads, no cookies. Your location is used on the phone to work out what's above you and isn't sent to us.

Official data

Every number comes from public science agencies, so you see what the scientists see.

Made to match

All four share one look: dark, compact, with tabs at the bottom and home-screen widgets.
