Galaxy Picker

About the images

Thirteen galaxies, each a real photograph — twelve from the NASA/ESA Hubble Space Telescope, plus our own Milky Way from ESO (all CC BY 4.0).

Discover a random galaxy, shown in a real image from the Hubble Space Telescope. Tap Reveal — the field comes into focus on one galaxy, and a card opens with its type, distance and the constellation you'd find it in. From the Whirlpool and the Sombrero to the colliding Antennae.

  • Real Hubble images
  • For astronomy class
  • A fresh galaxy each time
A window on the universe

The Galaxy Picker reveals a random galaxy — not as a name on a list, but as a real photograph from the Hubble Space Telescope. The field comes into focus on one galaxy, and a card opens with its type, its distance, and the constellation you'd point a telescope toward to find it.

Real images, not illustrations

Every galaxy here is shown in an actual image taken by the NASA/ESA Hubble Space Telescope — the Whirlpool's grand spiral, the Sombrero's dark dust lane, the Antennae galaxies mid-collision. Seeing the real thing is what turns "a galaxy" into something you remember. Use it to give every student a different galaxy to research, to open an astronomy lesson, or simply to fall down a cosmic rabbit hole.

What the card tells you

  • Type — spiral, barred spiral, elliptical, starburst, or a pair of colliding galaxies.
  • Distance — how far its light has travelled to reach us, in light-years.
  • Constellation — the patch of sky it sits in, from Ursa Major to Virgo.
  • Catalogue — its Messier or NGC number, so you can look it up or find it yourself.

Fair, and free

Each reveal is decided by a cryptographically fair random draw, so every galaxy has an exactly equal chance. Exploring the rest of the science shelf? Pair it with the Planet Picker for worlds closer to home, or the Space Mission Picker for the craft that explore them.

Frequently asked questions

Thirteen galaxies — starting with our own Milky Way, plus Andromeda, the Whirlpool, the Sombrero, the Pinwheel, the Cigar (M82), Bode's Galaxy, Centaurus A, the Antennae, Messier 106, Messier 77, NGC 1300 and NGC 1672.

Yes — every galaxy is shown in a genuine image taken by the NASA/ESA Hubble Space Telescope, not an illustration.

Because we live inside it — you can't photograph your own galaxy from the outside. So while the others are seen face-on through a telescope, the Milky Way is shown as we actually see it: its glowing band arching across the night sky, viewed edge-on from within.

Spirals and barred spirals, an elliptical (Centaurus A), a starburst galaxy (the Cigar) and a pair of colliding galaxies (the Antennae) — a good cross-section of the galaxy zoo.

Yes. The winner is chosen with your browser's cryptographically secure random generator, so every galaxy has an exactly equal chance.

Yes — after a reveal you can save the card, image and all, as a PNG, or tick "Download the card after each reveal" to get one automatically.
