Our very own galaxy — here are some amazing photos of the Milky Way taken in El Solitario, Spain back in 2017! IAYC is a perfect place to learn how to observe 🌌

All images were taken by leader Javier Barrios Martí during camp 🔭

The observing-focused working group isn’t the only place where you can learn how to use a telescope — the camp’s unique atmosphere fosters collaboration and connection during the entire 3-week experience. Fellow participants and leaders are more than happy to help you! :)

Big, bright, and spotty — these images were taken by participants at IAYC 2024. Due to the solar maximum, sunspots were highly visible for the duration of camp, and we were left with some lovely photos of our star (check how the sunspots move as the Sun rotates!) :)

When it comes to application gender statistics, we see more non-male applicants than male, which is not unique to our program. This trend is generally explained by traditional learning environments being best suited to males, thus non-males tend to seek alternative learning environments.
