These cosmic lighthouses emit periodic bursts of radiation from their magnetic poles, and now a team of researchers claim they have detected the largest burst ever recorded from a pulsar. A global collaboration of scientists used the H.E.S.S. Observatory in Namibia to observe a pulsar…

A Mysterious Object in Deep Space Has Blinked Every 22 Minutes for Over 30 Years
An intensely magnetic neutron star roughly 15,000 light-years from Earth is stumping astronomers with its ultra-long periods, unleashing radio waves into the cosmos every 22 minutes. Neutron stars with intense magnetic fields are called magnetars. Now, 22-minute periods may sound relatively frequent in Earthly time scales, but most magnetars have periods between a few seconds…
