The universe has a musical side. 🎶 Meet the Treble Clef, an unusual radio structure stretching more than 2 million light-years across space. Its shape is striking, but the science behind it is even more fascinating. Studying structures like this can reveal how galaxy clusters interact and evolve. In this composite, radio emission appears in red, X-rays in blue, and infrared data in white: go.nasa.gov/3WCV89U

One step closer to boots on the Moon! 🌙 To prepare for Moon Base, NASA needs to know what physical tasks crews can handle immediately after landing—and Artemis II provided some insight. Soon after splashdown, the crew suited up and tackled mission-critical tasks, demonstrating successful performance within hours of their return.

The data is out. So what happens next? Scientists, researchers, students, and curious minds around the world can dig in, ask new questions, and collaborate to deepen our understanding of the Moon. What we learn today can help inform future lunar missions as we explore the Moon and prepare to go farther.
