A new stellar object that is challenging our understanding of neutron stars has been discovered by Aussie and international astronomers. The researchers say that the object behaves a bit like a magnetar - a rare type of star with extremely strong magnetic fields that can produce powerful bursts of energy – but is unique because of how slowly it seems to be producing these bursts. All known magnetars release energy at intervals ranging from a few seconds to a few minutes, but the newly discovered object emits radio waves every 21 minutes, making it the longest period magnetar ever detected.
