O'Neill's map shows that indeed the magnetic-field lines do coincide with large sites of star formation on the surface of the Local Bubble, such as the Orion Molecular Cloud that is home to the ...

This correlates with the orientation of local magnetic field lines. Combined, this information builds a detailed map of the magnetic field in that arm of the galaxy. Credit: 2023 Doi et al.

Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields ... Two magnetic contrast maps. The cobalt rod is located in ...

exhibits a surprisingly ordered magnetic field, astronomers have discovered. The observations, detailed today in the journal Science, have resulted in the most detailed map yet of another galaxy's ...
