A distant galaxy has thrown up some unexpected surprises to astronomers, including superbubbles, giant loops and X-shaped magnetic field structures. Astronomers have been observing a spiral galaxy known as NGC 4217, which is 67 million lightyears away, in order to understand more about our Milky Way. Spiral galaxies can have sprawling magnetic fields, but why has always remained a bit of a mystery.

However, new research used radio observations to help unravel the enigma.

NGC 4217 has several "remarkable" structures which made it the ideal candidate to look at.

Most spiral galaxies contain a flat, rotating disk packed full of stars, gas and dust, but NGC 4217 threw up some unexpected surprises.

Radio observations revealed some of the strange structures, which include an X-shaped magnetic field and "superbubbles" of gas and dust.

The team revealed these structures and the odd magnetic field are caused by star formations and explosions sending the particles of the galaxy skewiff.

Dr Rainer Beck from the Max Planck Institute for Radio Astronomy in Bonn said: It is fascinating that we discover unexpected phenomena in every galaxy whenever we use radio polarisation measurements.

Here in NGC 4217, it is huge magnetic gas bubbles and a helix magnetic field that spirals upwards into the galaxys halo.

Dr Yelena Stein from Ruhr-Universitt Bochum, the Centre de Donnes astronomiques de Strasbourg and the Max Planck Institute for Radio Astronomy, added: Galaxy NGC 4217 is of particular interest to us.

This has never been observed before. We suspect that the structures are caused by star formation, because at these points matter is ejected outward.

Visualising the data was important to me. Because when you think about galaxies, magnetic fields is not the first thing that comes to mind, although they can be gigantic and display unique structures.

"The image is supposed to shift the magnetic fields more into focus.

However, the team concede more observations are needed to better understand the strange magnetic field, which extends as much as 22,500 lightyears beyond the galaxy's disk.

A statement from the University of New Mexico said: "A leading explanation, called the dynamo theory, suggests that magnetic fields are generated by the motion of plasma within the galaxy's disk.

"Ideas about the cause of the kinds of large vertical extensions seen in this image are more speculative, and astronomers hope that further observations and more analysis will answer some of the outstanding questions."
