To celebrate the longest lunar eclipse of this century, version 1.5 now shows the transition of the moon through the earth shadow (Gear VR only so far).

New version just released on the Oculus store! 1.4 now allows moving in time over hours, days, or months.

Sky by day and night

Visible objects include the constellations, sun, moon (with current phase), planets, and the Milky Way.


View the sky from your own GPS location, or the Earth’s poles – experience polar day and night! More locations will be added in future releases.


The landscape is essential in providing orientation and a sense of scale. Makes comparison to the real sky so much easier!

Time machine

Move to a specific point in time in a 24 hour range – fast forward midnight or back to sunrise. Experience the rotation of the sky in timelapse.

Time remote

Use your Gear VR’s touchpad to move through time more conveniently using swipe and pan gestures – spanning hours, days, or months.

Rise and set times

Rise and set times are displayed for the sun and the moon, as well as their current positions in the sky.

Voice chat

Invite a friend for a voice chat, and check out the sky at each other’s GPS locations. (Gear VR only)

Red filter

For users who like to take their VR glasses out at night: The red filter keeps your eyes adjusted to low light conditions.

Ecliptic and equator

The ecliptic and galactic equator display options provide more guidance in finding your way across the skies.

What’s this?

Pocket Observatory is a fun and educational astronomy VR experience, offering an intuitive, hands-on approach to learn about the skies above. Follow the motions of stars, sun, moon, and planets!

You're not alone

Invite a friend for a voice chat beneath the stars! On Gear VR, you can connect via the Oculus platform, and check out each other's local sky view. It's a great feature for educational purposes or just hanging out together.

  • Realistic day and night cycle - experience the sky around sunset, see which constellation the sun is in during the day.
  • Social VR - invite a friend for a voice chat (Gear VR only).
  • Built-in virtual landscape - together with the fantastic field of view in VR, the increased sense of scale will help you identify the constellations on the real sky.
  • Time controls for viewing a certain time of day, or adjusting time over hours, days, or months.
  • Different observation positions on earth - experience the sky from your own location, the north pole, or the south pole. When connected in a chat, the remote GPS location is available, too.
  • Pro features: Red filter for night-time use, ecliptic and galactic equator display


Here are a few ideas for things you can try out in Pocket Observatory:

  • Find out what stars and planets will be visible at your GPS location tonight.
  • Invite a friend to chat and visit each other's local sky views.
  • Watch the moon rise and check out the current lunar phase.
  • Preview an upcoming lunar eclipse.
  • Fast forward to sunrise, to see whether Venus is visible in the morning.
  • See how the sky rotates about the North Star on the northern hemisphere.
  • Let the sky revolve horizontally around you as you are standing on Earth's axis.
  • Experience polar day and night.
  • View the constellations on the other hemisphere.
  • Understand how everything on the sky flips upside down as you travel to the other half of the planet.
  • Discover the variations in the Milky Way in different parts of the sky.
  • See how the position of the sun relates to the zodiac on your birthday.
