An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy’s halo. The finding was reported in a paper published September 23 on the pre-print server arXiv.

Located some 61.6 million light years away, NGC 4217 is a nearby edge-on star-forming spiral galaxy. Previous observations of this galaxy have found that it contains dozens of absorbing dust structures with various morphologies. Moreover, a radio halo extending to about 16,000 light years from the galaxy’s star-forming disk has been identified.
Recently, a group of astronomers led by Volker Heesen of Hamburg University in Germany, has employed the Jansky Very Large Array (JVLA) and with LOw Frequency ARray (LOFAR), to take a closer look at NGC 4217 in radio band.
