Pinwheel galaxy boasts edgy star formation

[Rick]

New images from the Japanese infrared space telescope AKARI have revealed giant star-forming regions on the edge of the spiral galaxy M101. The findings suggest M101 is something of a special case, since star formation more usually happens in the denser central part of spiral galaxies.

The galaxy is roughly twice the size of our own Milky Way, and located roughly 27 million light years away in the Great Bear constellation.
