We Live In A Magnetic Universe – Galaxy Five Billion Light-Years Away Reveals
MessageToEagle.com – Astronomers observed the magnetic field of a galaxy five billion light-years away. The galaxy provides important insight into how magnetism in the universe formed and evolved.
With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a problem at the frontiers of cosmology — the nature and origin of the magnetic fields that play an important role in how galaxies develop over time.

With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a problem at the frontiers of cosmology — the nature and origin of the magnetic fields that play an important role in how galaxies develop over time.
“The results of our study support the idea that galaxy magnetic fields are generated by a rotating dynamo effect, similar to the process that produces the Sun’s magnetic field,” Mao said.
A chance combination of a gravitational lens and polarized waves coming from a distant quasar gave astronomers the tool needed to make a measurement important to understanding the origin of magnetic fields in galaxies.

“However, there are other processes that might be producing the magnetic fields. To determine which process is at work, we need to go still farther back in time — to more distant galaxies — and make similar measurements of their magnetic fields,” she added.
“This measurement provided the most stringent tests to date of how dynamos operate in galaxies,” said Ellen Zweibel from the University of Wisconsin-Madison.
