Cosmic Ray Detector SORAMAME 4+

Our app allows you to observe cosmic rays using your smartphone's camera sensor.

We are developing an app for observing cosmic rays. These cosmic rays, which constantly bombard us from space and even penetrate our bodies, are invisible to the naked eye. Our app allows you to observe these cosmic rays using your smartphone's camera sensor. You can view real-time images of potential cosmic ray detections and see a graph of detection frequency, updated in real time.

Our app is used by people all over the world. When a potential cosmic ray is detected, it is displayed on the app screen. You can also view images detected by other users in real-time on our website.

Since constant observation is necessary, we recommend using old smartphones and tablets that are no longer needed. The data collected through the app is used to explore unsolved problems in astrophysics, and we regularly present our latest research findings at conferences both domestically and internationally.

The app is developed and made available through a joint research project with the HIBINO Laboratory in the Department of Applied Physics at Kanagawa University.

Transforming Obsolete Devices into Tools for Cosmic Discovery

With over 6 billion smartphones in use worldwide, and more than 8 billion internet-connected devices when you include tablets and laptops, our world is more connected than ever. However, with new versions released almost every year, many of these devices are replaced in just a few short years. But what happens to them once they become obsolete?
These devices, though small, are powerful computers packed with valuable components. One of the most important parts is the camera sensor, found in nearly every device. This tiny, silicon-based CMOS camera sensor is at the heart of our innovative project, the 'Soramame' cosmic ray observation app.
By repurposing these used smartphones and tablets, we can create a global network of detectors, helping to push the boundaries of astrophysics. Join us in this exciting project, and turn your old device into a tool for cutting-edge research!
