VR app "Excursion to the Sun" has been released!





We started the free distribution of the new VR app "Excursion to the Sun," which provides a unique opportunity to walk around the solar surface and experience the fundamental structures of the Sun.

[Updated on June 7, 2021]: The distribution of the VR app "Excursion to the Sun" has ended on June 7, 2021. Thank you for using this app.

Overview of the app: Experience the Sun with observational data from the Hinode spacecraft!

Traveling through the space, you will approach the Sun, land on its surface, and... look! You will see the gigantic sunspots from which magnetic field lines extend up towards space. You can freely walk around the solar surface. Using the "Atmospheres" icon you can enjoy views of the various layers of the solar atmosphere. This VR app was designed by the Solar Science Observatory, National Astronomical Observatory of Japan.

Most of the visual images in the app are the actual observational data obtained by Hinode spacecraft.
Those under 13 years old can also play the app by using the "single-eye mode."

◇Collect 4 keys and watch the movies!
Walk around and seek the 4 keys hidden somewhere on the solar surface. Each time you get a key, you can enjoy a spectacular movie of the Hinode launch, the great flare eruption, etc.
