The AKARI Spacecraft made new observations of galaxy M101, revealing differing populations of stars spread across its spiral arms. Many young high-temperature stars populate the spiral arms, revealing the areas of star formation and warming the interstellar dust. This makes the galaxy shine at shorter infrared wavelengths. In contrast, the longer wavelengths show the "cold" dust. Normal stars, typically like our own Sun, warm this dust.
