Today on Wonder, we visit the Indonesian island of Java to discover a mesmerizing phenomenon: the blue-fire volcano. During the day, pale plumes of gas billow from the crater and fissures in the rock. But it’s at night that this volcano really comes alive. As the sun sets, it prepares to wow onlookers with a show of colors. Indigo-blue flames dance and leap from its craters, casting shadows across the turquoise lake below. In this week’s episode, we’re traveling to the volcano’s edge to witness this vision in blue. It’s time to put on your headphones, close your eyes, and take five minutes to yourself—to breathe, learn, and wonder.
