The NASA/ESA Hubble Space Telescope has made detailed observations of the dwarf galaxy NGC 2366. While it lacks the elegant spiral arms of many larger galaxies, NGC 2366 is home to a bright, star-forming nebula and is close enough for astronomers to discern its individual stars.

The chance discovery with ESA's INTEGRAL observatory, in 2004, of highly energetic X-rays emanating from a young neutron star with an extremely strong magnetic field, provided scientists with a challenge: to explain how these objects, also known as magnetars, produce such energetic non-thermal radiation. A new, comprehensive study of one...
